StoreKit2 Coexistence Issues with Original StoreKit
Background: My app uses a third-party SDK for payments, and it uses Original StoreKit internally for IAP payments. Now I'm getting ready to migrate to StoreKit2, and during the transition, users may use either method to initiate payments, and there's no way to avoid the coexistence of StoreKit2 and Original StoreKit. Problem: When a user has an unfinished transaction, if the app is restarted, both StoreKit2 and Original StoreKit will receive a notification of the transaction: Original StoreKit's '-paymentQueue:updatedTransactions:' method StoreKit2's 'Transaction.updated' method resulting in duplicate calls to the shipping API. My current treatment is to only add '-paymentQueue:updatedTransactions:' to listen for unfinished transactions. Even if the user is using StoreKit2 to initiate the payment, if the transaction is not Finished, it will be fetched via this method after restarting the app to process this transaction. Is this approach feasible and are there any best practices for this scenario? To summarize: Is it feasible to fetch unfinished StoreKit2 transactions via Original StoreKit methods when StoreKit2 coexists with Original StoreKit? Is there a recommended way

App Review cannot complete auto-renewable subscription purchase (Guideline 2.1) although sandbox & TestFlight work
Hello, I’m experiencing repeated rejections related to Guideline 2.1 – App Completeness for an iOS app using auto-renewable subscriptions, and I’m struggling to understand what is missing, as the purchase flow works correctly in sandbox and TestFlight. App setup: iOS app built with React Native (Expo + react-native-iap) Auto-renewable subscriptions: • Monthly: €4.99 • Yearly: €39.99 Paid Apps Agreement accepted Subscriptions configured and active in App Store Connect Privacy Policy and Apple Standard EULA included: • Visible inside the app on the subscription screen • Added in App Store metadata What App Review reports: App Review states they are unable to buy the in-app purchase, resulting in a rejection under Guideline 2.1 (App Completeness). What works correctly: getSubscriptions() returns valid products in sandbox Subscription titles, prices, and durations are displayed in the app UI requestSubscription() is triggered when tapping the subscribe button Apple purchase sheet appears and completes successfully in: • Sandbox testing • TestFlight (external testers) What I’ve verified: No conditional logic blocks purchases in review builds Purchase button always calls requestSubscription purchaseUpdatedListener and purchaseErrorListener are correctly registered No hardcoded prices; prices come from StoreKit Same behavior on iPhone and iPad Question: Is there any known limitation or requirement in the App Review environment for auto-renewable subscriptions that differs from sandbox/TestFlight when using a custom subscription UI (not SubscriptionStoreView)? If App Review requires a specific implementation detail (StoreKit 2, SubscriptionStoreView, or something else), I would really appreciate clarification, as this is not explicitly stated in the rejection. Thank you for your help.

Advanced commerce API - dynamic subscriptions
Hello, We have been approved for the Advanced commerce API and we are trying to implement dynamically created subscriptions via the SubscriptionCreateRequest. We followed the Sending Advanced Commerce API requests from your app (https://developer.apple.com/documentation/storekit/sending-advanced-commerce-api-requests-from-your-app) documentation but we are not able to make it work correctly. We created a generic subscription in the Appstore connect, product ID: com.example.subscription Then in the app we load the subscription: try await Product.products(for: ["com.example.subscription"]) We do the JWS serialization on our backend and then we wrap the jwt and convert it to Data in the app as this: let request = """ { "signatureInfo": { "token": "\(result.signedPayload)" } } """ let advancedCommerceRequestData = Data(request.utf8) Lastly, we apply the purchase options on the generic product as this: try await product.purchase( options: [ Product.PurchaseOption.custom( key: "advancedCommerceData", value: advancedCommerceRequestData ) ] ) It doesn't show any error, but on the payment sheet it shows the data from the generic subscription and not the data that was in the SubscriptionCreateRequest. Here is an example of the generated jwt: eyJraWQiOiI4V0tNQjhLWTI0IiwidHlwIjoiSldUIiwiYWxnIjoiRVMyNTYifQ.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.kJ0f_q2A11Mn9OBmvX6SRmtW5P--volFTVcq_Gohs3N51ECfZqS3WHOxOZc7aojq_qiUHGFp_evmHP51f3LzSw

StoreKit 2: Product.purchase() returns StoreKitError (2) when canceling "Pending Downgrade" in Production ONLY
Environment OS: iOS 26.2 ~ 26.3 SDK: Xcode 16.4 (Target: iOS 17.6) Framework: StoreKit 2 Environment: Production (Cannot reproduce in Sandbox or Xcode Configuration) Issue Description We are encountering a critical purchase failure that occurs exclusively in the Production environment. When a user who has a "Pending Downgrade" (scheduled for the next renewal date) attempts to re-purchase their current higher-tier product to cancel the downgrade, StoreKit 2 returns an error. Steps to Reproduce User is currently on "Product A" (Higher Tier). User schedules a downgrade to "Product B" (Lower Tier). The status changes to "Pending Downgrade". User attempts to purchase "Product A" again via Product.purchase(). The system purchase sheet appears, and the user confirms the purchase. Immediately after authentication, a system alert from StoreKit appears saying: "Cannot process request at this time. Please try again later." (現在リクエストを一時的に処理できません。しばらくしてからもう一度お試しください。) After dismissing the alert, the app receives StoreKitError code 2 (unknown) with the localized message: "Request could not be completed" (リクエストを完了できません). Technical Observations Transaction.currentEntitlements: Does not change. App Store Server Notifications (V2): No notifications are sent to our server. Sandbox Behavior: Works perfectly. Re-purchasing Product A successfully cancels the downgrade and the subscription remains at the Higher Tier. AppStore.sync(): Running a manual sync does not resolve the pending state after the error. Question Since we cannot debug production-level logs, we are stuck. Is this a known regression in the StoreKit 2 commerce engine regarding state synchronization for downgrades? Has anyone found a workaround for this specific scenario? Any insights would be greatly appreciated.

StoreKit 2: is there a way for an app to be informed in real time if an auto-renewable subscription is cancelled by the user?
Hello, In my iOS app, I have a customer center where the user can see some details about its current subscription. I display things like the billing period, the price, the introductory offer state, the renewal date if it's not cancelled or the expiration date if it's cancelled, etc. From this screen, the user can open the subscription management sheet. I want to detect if the user cancels the subscription from this sheet or from the App Store (when the app is running) so I can refresh the information displayed on my customer center. I checked the asynchronous sequences provided by StoreKit 2 like Transaction.updates or Product.SubscriptionInfo.Status.updates and tested with a Sandbox account on my physical device with the app debugged using Xcode. But I noticed these sequences don't emit when I cancel the subscription in Sandbox. Is this the expected behavior? Is there a way to observe in real time if a user cancels the subscription? I can still manually check when the sheet is dismissed but it's not ideal because I want to know even if the user cancel from outside of the app with the app running. Thank you, Axel

Issue with "Transaction.currentEntitlements": Some paid users cannot use the features of our subscription plan
Some paid users are unable to use the paid features unlocked by purchasing our subscription plan. It seems that this is due to StoreKit 2's Transaction.currentEntitlements not working the way we would expect it to work. Are you also encountering this issue? Do you have any idea to improve this situation? At launch, our app checks if the user is subscribed to the plan, using Transaction.currentEntitlements. As a result, the currentEntitlements array was empty. Our app then fetches the products from StoreKit 2 using Product.products(for:). As a result, the Product.SubscriptionInfo.RenewalState value of the corresponding Product (product.subscription.status.first.state) is subscribed, which confirms that the user has indeed purchased our plan, but seems to contradict the absence of the corresponding transaction in Transaction.currentEntitlements. Proactive in-app purchase restore and a restore purchase button calling the AppStore.sync() method are implemented, but using the button did not solve the issue.

Acknowledgment there is a subscription renewal problem?
New subscriptions have been failing to renew in the sandbox for 3 days. I am seeing multiple posts and comments from people that appear to be experiencing the same issue. But I haven't seen any feedback from Apple representatives. I really do not want to launch a new app without seeing functioning renewals in the sandbox. Is there somewhere else we are intended to seek assistance?

[macOS] AppTransaction questions (internet connection requirement)
Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? Thank you kindly, – Matthias

how to handle verification step for in-app purchase?
a UK-based user is having trouble completing an in-app purchase. after going through the typical purchase flow (tapping the button to trigger the in-app purchase sheet, completing Face ID) they see this verification sheet appear over my app and have to go to their banking app to approve the purchase. after approving the purchase from their banking app, they tap "Payment confirmed on Mobile App" to close the sheet, but then see an alert that suggests the result is .userCancelled. the purchase does not seem to have completed. the user reports not being charged (despite numerous attempts). plus, i have a "restore purchases" function on App init that would've restored a purchase if it existed. i have implemented what i think is a typical Storekit.purchase() method (again, the message the user sees is for the .userCancelled case): func purchase(productId: String) async -> (Bool, String?) { guard let product = subscriptionProducts.first(where: { $0.id == productId }) else { return (false, "Product not found") } do { let result = try await product.purchase() switch result { case .success(let verification): switch verification { case .verified(let transaction): await transaction.finish() hasSubscription = true return (true, nil) case .unverified: return (false, "Transaction verification failed") } case .userCancelled: return (false, "No worries, take your time. 😌") case .pending: return (false, "Purchase is pending") u/unknown default: return (false, "Error purchasing product. If this keeps happening, please contact [email].") } } catch { return (false, "Error purchasing product: \(error.localizedDescription)") } } has anyone dealt with this issue? i was seeing an unusually high number of .userCancelled purchase events from users outside the US, and i'm wondering if some of them were genuine purchase attempts that were blocked by this verification step. 😕

Resending notifications from Apple
Regarding App Store Server Notifications V2,we are currently using Notifications V2 in a production environment. It is set up so that if the server receives the notification successfully, it returns 200 after about 30 seconds, and if an error occurs, it returns 400 or 500. However, the notification is being resent multiple times from Apple's server, at 1 hour, 12 hours, and 24 hours. Is it necessary to return the notification using Apple's API?

Advanced Commerce (Sandbox) – Generic Product Still “Ready to Submit”
Hello, Our app is approved for the Advanced Commerce API and we are currently testing in the Sandbox environment only. We have created generic product identifiers and have already submitted them via the Advanced Commerce API Access form. However, the generic product status in App Store Connect is still “Ready to Submit.” For Sandbox testing, is this status expected, or do we need to submit an app build or the generic product for review before Advanced Commerce works correctly? Thank you.

IAP receipt validation fails with status code: 21002
I have implemented IAP. The purchases are successful. The refresh receipt is working fine, which then calls the requestDidFinish(_ request: SKRequest) delegate. I'm fetching the receipt url through 'Bundle.main.appStoreReceiptURL'. When I convert the receipt data in base64 string and send it to app store's sandbox api and try to validate the receipt, it fails giving status code : 21002.

RequestReviewAction never triggering rating dialog
Hello, We are having an issue with the RequestReview API and were hoping to get some help. We know that there is no guarantee that the in-app review modal will show and we know that there are 3 circumstances in which it will definitely not appear: if the user has turned off in-app review/ratings in their settings if the user has submitted a review for that app on that device within the last 365 days if the user has been asked for a review >3 times in the last 365 days When testing our implementation, every single one of our testers did not receive the rating modal despite the fact that we had all our testers turn on the app rating setting and that we have never asked for reviews from our app before. So that seems suspicious. While it is possible that something is up with our code (and I have provided some snippets below) we are also concerned that apple maybe is suppressing it for another reason. We really want to go live with our app review code but unfortunately we are not able to get confidence that it will ever appear for the user. Can you please help us understand why this isn't working. The code: We are using the SwiftUI approach to requesting review. Here are some relevant code snippets Important to note, we have a modal that appears when the user is in our list of active, targeted users. If they tap yes on this modal, it should show the in app rate the app system modal. If they tap no, we present them with an airship survey so that they can give feedback. Here is the code for the Yes button action: @Environment(\.requestReview) private var requestReview private var yesButton: some View { Button( action: { dismiss() requestReview() }, label: { Text(Lingua.General.appRateFirstButton) .regularParagraph() .frame(width: 180, height: 35) } ) .customButtonStyle( foregroundColor: .black, backgroundColor: Color(.powderBlue), radius: 36 ) } and this is the logic we use to determine whether we want to show them the modal in the first place. Obviously, a lot of this code leads to deeper areas in our logic and code but to give an idea... private func showAppRateModalIfNeeded() { if preferencesManager.appRateReviewShown == nil, accountManager.userAccount?.permissions.rateTheApp == true { let appReviewModalVC = UIHostingController(rootView: AppReviewModal()) appReviewModalVC.view.backgroundColor = .init(white: 0, alpha: 0.6) appReviewModalVC.modalPresentationStyle = .overFullScreen appReviewModalVC.modalTransitionStyle = .crossDissolve parentVC?.navigationController?.present(appReviewModalVC, animated: true) preferencesManager.appRateReviewShown = true } } When testing in debug, we do find that the modal appears and works as expected. However, on release builds nobody is able to trigger it. Why? Are we doing something wrong here or is Apple just suppressing it. We are thinking about implementing the button taking the user directly into the app store review but we'd prefer to do the lower-friction dialog in-app if we can get it work so the user doesn't get sent out of the app.

Unable to sign in to Sandbox Apple Account on Simulator
I am unable to sign in to a Sandbox Apple Account, where this issue occurs only via Simulator. Under Settings > Developer, I tap "Sign In" under Sandbox Apple Account. I enter my account credentials, and after bringing me back to the Developer page, the Sign In button briefly appears as disabled, before being re-enabled, without signing in to the account. (The account credentials are also recognized as correct, as I will receive an alert popup if incorrect.) See screenshots below: After signing in, Sign In button appears disabled... ... then is re-enabled without actually signing in to the account. I have now tried setting up multiple sandbox accounts via App Store Connect with various permutations (no confirmation of Apple Account email, confirming Apple Account email, logging in to iCloud and accepting terms of service), running different device simulators, running simulators on different Mac computers... none of which yield a different result. By contrast, I can sign in to the Sandbox Apple Account without issue on a physical device. The problem occurs only via Simulator.

Unable to enable eligibility for External Purchase Link APIs — seeking clarification
Hello, I am currently implementing External Purchase Link and External Purchase Custom Link and am encountering an issue where both ExternalPurchaseLink.canOpen and ExternalPurchaseCustomLink.isEligible always return false under all test conditions. I would like to confirm whether my setup is missing any required steps or whether this behavior is expected. Below are the details of my current environment and configuration: 🔧 1. Development Environment Xcode: 16.3, 16.4, 26.0 beta 4 Devices: iPhone running iOS 26.2 beta iPhone running iOS 16.7.12 macOS 15.5 (real device testing) Simulator iOS 18.0 Build Type: Local development build using a Developer Provisioning Profile Sandbox account signed in during testing 🔑 2. Entitlements (Developer site & Xcode) In Certificates → Identifiers → App ID, both capabilities are enabled: StoreKit External Purchase StoreKit External Purchase Link The .entitlements file in Xcode includes: com.apple.developer.storekit.external-purchase = YES com.apple.developer.storekit.external-purchase-link = YES The Provisioning Profile also contains both entitlements (confirmed via codesign -d --entitlements :-). 📄 3. Info.plist Configuration Both keys are configured with correct region codes according to documentation: SKExternalPurchase SKExternalPurchaseCustomLinkRegions 🌍 4. Test Storefront Device storefront verified as United States (US) or Portugal (PT) (US = target region for External Purchase Link, PT = EU region) But despite all the above configuration, both API calls consistently return false: ExternalPurchaseLink.canOpen // false ExternalPurchaseCustomLink.isEligible // false So I cannot proceed to testing the remaining flow (token retrieval, link opening, etc.) ------ Questions ------ ❓ Q1) Local Development Build Limitation Is it expected behavior that Developer-signed local builds always return canOpen = false / isEligible = false for External Purchase Link & Custom Link? Is there a technical or policy restriction that prevents eligibility in local dev builds? ❓ Q2) App Store Connect Configuration Requirement Are there mandatory App Store Connect settings (such as external purchase URLs, support URL, disclosures, or country configuration) that must be enabled before eligibility becomes true? Currently, no External Purchase Link or Custom Link menu is visible in my App Store Connect app settings. Is this menu only available after certain approvals or under specific conditions? ❓ Q3) TestFlight Requirement Do External Purchase Link and Custom Link only return eligibility = true on: TestFlight builds, or Distribution-signed builds? Or should eligibility also work on developer builds? Formal confirmation would be helpful. ❓ Q4) Developer Account Type Limitation We are using an Individual Developer Account (not Organization). Can Individual accounts fully request, test, and ship apps using: External Purchase Link External Purchase Custom Link Or are there limitations on account type? 🙏 Request We have completed all documented setup steps (Entitlements → Provisioning → Info.plist), but eligibility remains false, blocking feature validation. Please clarify which of the following is the cause: Local development builds do not support eligibility Missing App Store Connect configuration (not visible to us) Account type restriction Region rollout or entitlement approval requirement Any additional setup not documented publicly Thank you for your assistance.

SKTestSession.setSimulatedError() not working for .loadProducts API in iOS 26.2
Description SKTestSession.setSimulatedError() does not throw the configured error when testing StoreKit with the .loadProducts API in iOS 26.2. The simulated error is ignored, and products load successfully instead. Environment iOS: 26.2 (Simulator) Xcode: 26.2 beta 2 (Build 17C5038g) macOS: 15.6.1 Framework: StoreKitTest Testing Framework: Swift Testing base project: https://developer.apple.com/documentation/StoreKit/implementing-a-store-in-your-app-using-the-storekit-api Expected Behavior After calling session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts), the subsequent call to Product.products(for:) should throw StoreKitError.notAvailableInStorefront. Actual Behavior The error is not thrown. Products load successfully as if setSimulatedError() was never called. Steps to Reproduce Create an SKTestSession with a StoreKit configuration file Call session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts) Call Product.products(for:) with a valid product ID Observe that no error is thrown and the product loads successfully Sample Code import StoreKitTest import Testing struct SKDemoTests { let productID: String = "plus.standard" @Test func testSimulatedErrorForLoadProducts() async throws { let storeKitConfigURL = try Self.getStoreKitConfigurationURL() let session = try SKTestSession(contentsOf: storeKitConfigURL) try await session.setSimulatedError( .generic(.notAvailableInStorefront), forAPI: .loadProducts ) try await confirmation("StoreKitError throw") { throwStoreKitError in do { _ = try await Self.execute(productID: productID) } catch let error as StoreKitError { guard case StoreKitError.notAvailableInStorefront = error else { throw error } throwStoreKitError() } catch { Issue.record( "Expect StoreKitError. Error: \(error.localizedDescription)" ) } } #expect(session.allTransactions().isEmpty) } static func execute(productID: String) async throws { guard let product = try await Product.products(for: [productID]).first( where: { $0.id == productID }) else { throw NSError( domain: "SKDemoTests", code: 404, userInfo: [NSLocalizedDescriptionKey: "Product not found for ID: \(productID)"] ) } _ = product } static func getStoreKitConfigurationURL() throws -> URL { guard let bundle = Bundle(identifier: "your.bundle.identifier"), let url = bundle.url(forResource: "Products", withExtension: "storekit") else { fatalError("StoreKit configuration not found") } return url } } Test Result The test fails because the expected StoreKitError.notAvailableInStorefront is never thrown. Question Is this a known issue in iOS 26.2 / Xcode 26.2 beta 2, or is there a different approach required for simulating errors with SKTestSession in this version? Any guidance would be appreciated.

Promotional offer purchase fails in Sandbox with ASDServerErrorDomain 3902 after payment sheet
Hello, I’m integrating promotional offers for auto-renewable subscriptions using StoreKit 2. The offer is displayed correctly, the Apple purchase sheet appears, and I can start the payment flow. The sheet shows the correct discounted price and the end date of the offer. However, after confirming the purchase, an alert appears saying “Unable to Purchase - Contact the developer for more information” When dismissing the alert, Xcode logs the following: Purchase did not return a transaction: Error Domain=ASDServerErrorDomain Code=3902 "No se ha podido realizar la compra" UserInfo={ NSLocalizedFailureReason=No se ha podido realizar la compra, client-environment-type=Sandbox, AMSServerErrorCode=3902, storefront-country-code=ESP } Test environment: App installed from Xcode on a real iPhone Logged in with a Sandbox Apple ID Using StoreKit 2 Promotional offer applied using: Product.PurchaseOption.promotionalOffer(_:compactJWS:) On the server side, I generate the promotional offer signature exactly as described in Apple’s documentation: https://developer.apple.com/documentation/storekit/generating-a-signature-for-promotional-offers The signature is generated using a Subscription Key Signed with ECDSA + SHA256 Uses the correct invisible separator (U+2063) The signature is validated locally using the derived public key and verifies correctly The sandbox user has had previous subscriptions, which is why this promotional offer is eligible and shown. Given that: The offer is displayed correctly The purchase sheet shows the discounted price and duration The signature validates locally The error occurs only after confirming the purchase My question is: Is this a known limitation or issue with promotional offers in the Sandbox environment? Should promotional offers be tested exclusively via TestFlight instead of Sandbox? Any clarification would be greatly appreciated. Thank you!

Advanced commerce API - dynamic subscriptions
Hello, We have been approved for the Advanced commerce API and we are trying to implement dynamically created subscriptions via the SubscriptionCreateRequest. We followed the Sending Advanced Commerce API requests from your app (https://developer.apple.com/documentation/storekit/sending-advanced-commerce-api-requests-from-your-app) documentation but we are not able to make it work correctly. We created a generic subscription in the Appstore connect, product ID: com.example.subscription Then in the app we load the subscription: try await Product.products(for: ["com.example.subscription"]) We do the JWS serialization on our backend and then we wrap the jwt and convert it to Data in the app as this: let request = """ { "signatureInfo": { "token": "\(result.signedPayload)" } } """ let advancedCommerceRequestData = Data(request.utf8) Lastly, we apply the purchase options on the generic product as this: try await product.purchase( options: [ Product.PurchaseOption.custom( key: "advancedCommerceData", value: advancedCommerceRequestData ) ] ) It doesn't show any error, but on the payment sheet it shows the data from the generic subscription and not the data that was in the SubscriptionCreateRequest. Here is an example of the generated jwt: eyJraWQiOiI4V0tNQjhLWTI0IiwidHlwIjoiSldUIiwiYWxnIjoiRVMyNTYifQ.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.kJ0f_q2A11Mn9OBmvX6SRmtW5P--volFTVcq_Gohs3N51ECfZqS3WHOxOZc7aojq_qiUHGFp_evmHP51f3LzSw

StoreKit 2: Product.purchase() returns StoreKitError (2) when canceling "Pending Downgrade" in Production ONLY
Environment OS: iOS 26.2 ~ 26.3 SDK: Xcode 16.4 (Target: iOS 17.6) Framework: StoreKit 2 Environment: Production (Cannot reproduce in Sandbox or Xcode Configuration) Issue Description We are encountering a critical purchase failure that occurs exclusively in the Production environment. When a user who has a "Pending Downgrade" (scheduled for the next renewal date) attempts to re-purchase their current higher-tier product to cancel the downgrade, StoreKit 2 returns an error. Steps to Reproduce User is currently on "Product A" (Higher Tier). User schedules a downgrade to "Product B" (Lower Tier). The status changes to "Pending Downgrade". User attempts to purchase "Product A" again via Product.purchase(). The system purchase sheet appears, and the user confirms the purchase. Immediately after authentication, a system alert from StoreKit appears saying: "Cannot process request at this time. Please try again later." (現在リクエストを一時的に処理できません。しばらくしてからもう一度お試しください。) After dismissing the alert, the app receives StoreKitError code 2 (unknown) with the localized message: "Request could not be completed" (リクエストを完了できません). Technical Observations Transaction.currentEntitlements: Does not change. App Store Server Notifications (V2): No notifications are sent to our server. Sandbox Behavior: Works perfectly. Re-purchasing Product A successfully cancels the downgrade and the subscription remains at the Higher Tier. AppStore.sync(): Running a manual sync does not resolve the pending state after the error. Question Since we cannot debug production-level logs, we are stuck. Is this a known regression in the StoreKit 2 commerce engine regarding state synchronization for downgrades? Has anyone found a workaround for this specific scenario? Any insights would be greatly appreciated.

StoreKit 2: is there a way for an app to be informed in real time if an auto-renewable subscription is cancelled by the user?
Hello, In my iOS app, I have a customer center where the user can see some details about its current subscription. I display things like the billing period, the price, the introductory offer state, the renewal date if it's not cancelled or the expiration date if it's cancelled, etc. From this screen, the user can open the subscription management sheet. I want to detect if the user cancels the subscription from this sheet or from the App Store (when the app is running) so I can refresh the information displayed on my customer center. I checked the asynchronous sequences provided by StoreKit 2 like Transaction.updates or Product.SubscriptionInfo.Status.updates and tested with a Sandbox account on my physical device with the app debugged using Xcode. But I noticed these sequences don't emit when I cancel the subscription in Sandbox. Is this the expected behavior? Is there a way to observe in real time if a user cancels the subscription? I can still manually check when the sheet is dismissed but it's not ideal because I want to know even if the user cancel from outside of the app with the app running. Thank you, Axel

Issue with "Transaction.currentEntitlements": Some paid users cannot use the features of our subscription plan
Some paid users are unable to use the paid features unlocked by purchasing our subscription plan. It seems that this is due to StoreKit 2's Transaction.currentEntitlements not working the way we would expect it to work. Are you also encountering this issue? Do you have any idea to improve this situation? At launch, our app checks if the user is subscribed to the plan, using Transaction.currentEntitlements. As a result, the currentEntitlements array was empty. Our app then fetches the products from StoreKit 2 using Product.products(for:). As a result, the Product.SubscriptionInfo.RenewalState value of the corresponding Product (product.subscription.status.first.state) is subscribed, which confirms that the user has indeed purchased our plan, but seems to contradict the absence of the corresponding transaction in Transaction.currentEntitlements. Proactive in-app purchase restore and a restore purchase button calling the AppStore.sync() method are implemented, but using the button did not solve the issue.

Acknowledgment there is a subscription renewal problem?
New subscriptions have been failing to renew in the sandbox for 3 days. I am seeing multiple posts and comments from people that appear to be experiencing the same issue. But I haven't seen any feedback from Apple representatives. I really do not want to launch a new app without seeing functioning renewals in the sandbox. Is there somewhere else we are intended to seek assistance?

[macOS] AppTransaction questions (internet connection requirement)
Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? Thank you kindly, – Matthias

how to handle verification step for in-app purchase?
a UK-based user is having trouble completing an in-app purchase. after going through the typical purchase flow (tapping the button to trigger the in-app purchase sheet, completing Face ID) they see this verification sheet appear over my app and have to go to their banking app to approve the purchase. after approving the purchase from their banking app, they tap "Payment confirmed on Mobile App" to close the sheet, but then see an alert that suggests the result is .userCancelled. the purchase does not seem to have completed. the user reports not being charged (despite numerous attempts). plus, i have a "restore purchases" function on App init that would've restored a purchase if it existed. i have implemented what i think is a typical Storekit.purchase() method (again, the message the user sees is for the .userCancelled case): func purchase(productId: String) async -> (Bool, String?) { guard let product = subscriptionProducts.first(where: { $0.id == productId }) else { return (false, "Product not found") } do { let result = try await product.purchase() switch result { case .success(let verification): switch verification { case .verified(let transaction): await transaction.finish() hasSubscription = true return (true, nil) case .unverified: return (false, "Transaction verification failed") } case .userCancelled: return (false, "No worries, take your time. 😌") case .pending: return (false, "Purchase is pending") u/unknown default: return (false, "Error purchasing product. If this keeps happening, please contact [email].") } } catch { return (false, "Error purchasing product: \(error.localizedDescription)") } } has anyone dealt with this issue? i was seeing an unusually high number of .userCancelled purchase events from users outside the US, and i'm wondering if some of them were genuine purchase attempts that were blocked by this verification step. 😕

Resending notifications from Apple
Regarding App Store Server Notifications V2,we are currently using Notifications V2 in a production environment. It is set up so that if the server receives the notification successfully, it returns 200 after about 30 seconds, and if an error occurs, it returns 400 or 500. However, the notification is being resent multiple times from Apple's server, at 1 hour, 12 hours, and 24 hours. Is it necessary to return the notification using Apple's API?

Advanced Commerce (Sandbox) – Generic Product Still “Ready to Submit”
Hello, Our app is approved for the Advanced Commerce API and we are currently testing in the Sandbox environment only. We have created generic product identifiers and have already submitted them via the Advanced Commerce API Access form. However, the generic product status in App Store Connect is still “Ready to Submit.” For Sandbox testing, is this status expected, or do we need to submit an app build or the generic product for review before Advanced Commerce works correctly? Thank you.

IAP receipt validation fails with status code: 21002
I have implemented IAP. The purchases are successful. The refresh receipt is working fine, which then calls the requestDidFinish(_ request: SKRequest) delegate. I'm fetching the receipt url through 'Bundle.main.appStoreReceiptURL'. When I convert the receipt data in base64 string and send it to app store's sandbox api and try to validate the receipt, it fails giving status code : 21002.

RequestReviewAction never triggering rating dialog
Hello, We are having an issue with the RequestReview API and were hoping to get some help. We know that there is no guarantee that the in-app review modal will show and we know that there are 3 circumstances in which it will definitely not appear: if the user has turned off in-app review/ratings in their settings if the user has submitted a review for that app on that device within the last 365 days if the user has been asked for a review >3 times in the last 365 days When testing our implementation, every single one of our testers did not receive the rating modal despite the fact that we had all our testers turn on the app rating setting and that we have never asked for reviews from our app before. So that seems suspicious. While it is possible that something is up with our code (and I have provided some snippets below) we are also concerned that apple maybe is suppressing it for another reason. We really want to go live with our app review code but unfortunately we are not able to get confidence that it will ever appear for the user. Can you please help us understand why this isn't working. The code: We are using the SwiftUI approach to requesting review. Here are some relevant code snippets Important to note, we have a modal that appears when the user is in our list of active, targeted users. If they tap yes on this modal, it should show the in app rate the app system modal. If they tap no, we present them with an airship survey so that they can give feedback. Here is the code for the Yes button action: @Environment(\.requestReview) private var requestReview private var yesButton: some View { Button( action: { dismiss() requestReview() }, label: { Text(Lingua.General.appRateFirstButton) .regularParagraph() .frame(width: 180, height: 35) } ) .customButtonStyle( foregroundColor: .black, backgroundColor: Color(.powderBlue), radius: 36 ) } and this is the logic we use to determine whether we want to show them the modal in the first place. Obviously, a lot of this code leads to deeper areas in our logic and code but to give an idea... private func showAppRateModalIfNeeded() { if preferencesManager.appRateReviewShown == nil, accountManager.userAccount?.permissions.rateTheApp == true { let appReviewModalVC = UIHostingController(rootView: AppReviewModal()) appReviewModalVC.view.backgroundColor = .init(white: 0, alpha: 0.6) appReviewModalVC.modalPresentationStyle = .overFullScreen appReviewModalVC.modalTransitionStyle = .crossDissolve parentVC?.navigationController?.present(appReviewModalVC, animated: true) preferencesManager.appRateReviewShown = true } } When testing in debug, we do find that the modal appears and works as expected. However, on release builds nobody is able to trigger it. Why? Are we doing something wrong here or is Apple just suppressing it. We are thinking about implementing the button taking the user directly into the app store review but we'd prefer to do the lower-friction dialog in-app if we can get it work so the user doesn't get sent out of the app.

Unable to sign in to Sandbox Apple Account on Simulator
I am unable to sign in to a Sandbox Apple Account, where this issue occurs only via Simulator. Under Settings > Developer, I tap "Sign In" under Sandbox Apple Account. I enter my account credentials, and after bringing me back to the Developer page, the Sign In button briefly appears as disabled, before being re-enabled, without signing in to the account. (The account credentials are also recognized as correct, as I will receive an alert popup if incorrect.) See screenshots below: After signing in, Sign In button appears disabled... ... then is re-enabled without actually signing in to the account. I have now tried setting up multiple sandbox accounts via App Store Connect with various permutations (no confirmation of Apple Account email, confirming Apple Account email, logging in to iCloud and accepting terms of service), running different device simulators, running simulators on different Mac computers... none of which yield a different result. By contrast, I can sign in to the Sandbox Apple Account without issue on a physical device. The problem occurs only via Simulator.

Unable to enable eligibility for External Purchase Link APIs — seeking clarification
Hello, I am currently implementing External Purchase Link and External Purchase Custom Link and am encountering an issue where both ExternalPurchaseLink.canOpen and ExternalPurchaseCustomLink.isEligible always return false under all test conditions. I would like to confirm whether my setup is missing any required steps or whether this behavior is expected. Below are the details of my current environment and configuration: 🔧 1. Development Environment Xcode: 16.3, 16.4, 26.0 beta 4 Devices: iPhone running iOS 26.2 beta iPhone running iOS 16.7.12 macOS 15.5 (real device testing) Simulator iOS 18.0 Build Type: Local development build using a Developer Provisioning Profile Sandbox account signed in during testing 🔑 2. Entitlements (Developer site & Xcode) In Certificates → Identifiers → App ID, both capabilities are enabled: StoreKit External Purchase StoreKit External Purchase Link The .entitlements file in Xcode includes: com.apple.developer.storekit.external-purchase = YES com.apple.developer.storekit.external-purchase-link = YES The Provisioning Profile also contains both entitlements (confirmed via codesign -d --entitlements :-). 📄 3. Info.plist Configuration Both keys are configured with correct region codes according to documentation: SKExternalPurchase SKExternalPurchaseCustomLinkRegions 🌍 4. Test Storefront Device storefront verified as United States (US) or Portugal (PT) (US = target region for External Purchase Link, PT = EU region) But despite all the above configuration, both API calls consistently return false: ExternalPurchaseLink.canOpen // false ExternalPurchaseCustomLink.isEligible // false So I cannot proceed to testing the remaining flow (token retrieval, link opening, etc.) ------ Questions ------ ❓ Q1) Local Development Build Limitation Is it expected behavior that Developer-signed local builds always return canOpen = false / isEligible = false for External Purchase Link & Custom Link? Is there a technical or policy restriction that prevents eligibility in local dev builds? ❓ Q2) App Store Connect Configuration Requirement Are there mandatory App Store Connect settings (such as external purchase URLs, support URL, disclosures, or country configuration) that must be enabled before eligibility becomes true? Currently, no External Purchase Link or Custom Link menu is visible in my App Store Connect app settings. Is this menu only available after certain approvals or under specific conditions? ❓ Q3) TestFlight Requirement Do External Purchase Link and Custom Link only return eligibility = true on: TestFlight builds, or Distribution-signed builds? Or should eligibility also work on developer builds? Formal confirmation would be helpful. ❓ Q4) Developer Account Type Limitation We are using an Individual Developer Account (not Organization). Can Individual accounts fully request, test, and ship apps using: External Purchase Link External Purchase Custom Link Or are there limitations on account type? 🙏 Request We have completed all documented setup steps (Entitlements → Provisioning → Info.plist), but eligibility remains false, blocking feature validation. Please clarify which of the following is the cause: Local development builds do not support eligibility Missing App Store Connect configuration (not visible to us) Account type restriction Region rollout or entitlement approval requirement Any additional setup not documented publicly Thank you for your assistance.

SKTestSession.setSimulatedError() not working for .loadProducts API in iOS 26.2
Description SKTestSession.setSimulatedError() does not throw the configured error when testing StoreKit with the .loadProducts API in iOS 26.2. The simulated error is ignored, and products load successfully instead. Environment iOS: 26.2 (Simulator) Xcode: 26.2 beta 2 (Build 17C5038g) macOS: 15.6.1 Framework: StoreKitTest Testing Framework: Swift Testing base project: https://developer.apple.com/documentation/StoreKit/implementing-a-store-in-your-app-using-the-storekit-api Expected Behavior After calling session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts), the subsequent call to Product.products(for:) should throw StoreKitError.notAvailableInStorefront. Actual Behavior The error is not thrown. Products load successfully as if setSimulatedError() was never called. Steps to Reproduce Create an SKTestSession with a StoreKit configuration file Call session.setSimulatedError(.generic(.notAvailableInStorefront), forAPI: .loadProducts) Call Product.products(for:) with a valid product ID Observe that no error is thrown and the product loads successfully Sample Code import StoreKitTest import Testing struct SKDemoTests { let productID: String = "plus.standard" @Test func testSimulatedErrorForLoadProducts() async throws { let storeKitConfigURL = try Self.getStoreKitConfigurationURL() let session = try SKTestSession(contentsOf: storeKitConfigURL) try await session.setSimulatedError( .generic(.notAvailableInStorefront), forAPI: .loadProducts ) try await confirmation("StoreKitError throw") { throwStoreKitError in do { _ = try await Self.execute(productID: productID) } catch let error as StoreKitError { guard case StoreKitError.notAvailableInStorefront = error else { throw error } throwStoreKitError() } catch { Issue.record( "Expect StoreKitError. Error: \(error.localizedDescription)" ) } } #expect(session.allTransactions().isEmpty) } static func execute(productID: String) async throws { guard let product = try await Product.products(for: [productID]).first( where: { $0.id == productID }) else { throw NSError( domain: "SKDemoTests", code: 404, userInfo: [NSLocalizedDescriptionKey: "Product not found for ID: \(productID)"] ) } _ = product } static func getStoreKitConfigurationURL() throws -> URL { guard let bundle = Bundle(identifier: "your.bundle.identifier"), let url = bundle.url(forResource: "Products", withExtension: "storekit") else { fatalError("StoreKit configuration not found") } return url } } Test Result The test fails because the expected StoreKitError.notAvailableInStorefront is never thrown. Question Is this a known issue in iOS 26.2 / Xcode 26.2 beta 2, or is there a different approach required for simulating errors with SKTestSession in this version? Any guidance would be appreciated.

Promotional offer purchase fails in Sandbox with ASDServerErrorDomain 3902 after payment sheet
Hello, I’m integrating promotional offers for auto-renewable subscriptions using StoreKit 2. The offer is displayed correctly, the Apple purchase sheet appears, and I can start the payment flow. The sheet shows the correct discounted price and the end date of the offer. However, after confirming the purchase, an alert appears saying “Unable to Purchase - Contact the developer for more information” When dismissing the alert, Xcode logs the following: Purchase did not return a transaction: Error Domain=ASDServerErrorDomain Code=3902 "No se ha podido realizar la compra" UserInfo={ NSLocalizedFailureReason=No se ha podido realizar la compra, client-environment-type=Sandbox, AMSServerErrorCode=3902, storefront-country-code=ESP } Test environment: App installed from Xcode on a real iPhone Logged in with a Sandbox Apple ID Using StoreKit 2 Promotional offer applied using: Product.PurchaseOption.promotionalOffer(_:compactJWS:) On the server side, I generate the promotional offer signature exactly as described in Apple’s documentation: https://developer.apple.com/documentation/storekit/generating-a-signature-for-promotional-offers The signature is generated using a Subscription Key Signed with ECDSA + SHA256 Uses the correct invisible separator (U+2063) The signature is validated locally using the derived public key and verifies correctly The sandbox user has had previous subscriptions, which is why this promotional offer is eligible and shown. Given that: The offer is displayed correctly The purchase sheet shows the discounted price and duration The signature validates locally The error occurs only after confirming the purchase My question is: Is this a known limitation or issue with promotional offers in the Sandbox environment? Should promotional offers be tested exclusively via TestFlight instead of Sandbox? Any clarification would be greatly appreciated. Thank you!

App extension write data The main target reads data.
I have an iOS app with a main target and an app extension. I want the app extension to write data to the SwiftData in App Groups, while the main target reads the data. However, currently, the app extension only has permission to read data, not to write it.Is the issue due to my incorrect configuration or an Apple-imposed restriction?
