New features for APNs token authentication now available
Team-scoped keys introduce the ability to restrict your token authentication keys to either development or production environments. Topic-specific keys in addition to environment isolation allow you to associate each key with a specific Bundle ID streamlining key management. For detailed instructions on accessing these features, read our updated documentation on establishing a token-based connection to APNs.

Get Transaction History
https://developer.apple.com/documentation/appstoreserverapi/get-v2-history-_transactionid I would like to inquire about the detailed triggers for updating receipts in this API specification. Recently, I was using this API with sort=DESCENDING&revoked=false to retrieve the expiration date of the most recent receipt and determine the subscription status. However, for some reason, an old receipt with an earlier expiration date appeared as the first receipt, and I would like to know the reason for this. Can you provide information on what specific events or actions trigger the updating of receipts in this API? Also, regarding https://developer.apple.com/documentation/appstoreserverapi/status, will statuses 3 and 4 not be returned in the response unless the billing grace period is enabled in the App Store?

Apple Pay Merchant Token on Web
Hello. I have a few questions about the implementation of Apple Pay payments on websites. Could you help me From the documentation: Apple Pay issues an Apple Pay Merchant Token if the user’s payment network supports merchant-specific payment tokens. Otherwise, Apple Pay issues a device token for the payment request. How can we determine whether a token is a merchant token or a device token? Is it possible to determine this by any of the token fields? https://developer.apple.com/documentation/passkit/payment-token-format-reference Is it possible to understand this in other ways? Can I make recurring payments with the device token if it was issued instead of the merchant token? Is it necessary to include the tokenNotificationURL when generating a merchant token, or can we generate one without specifying it? What does the applicationExpirationDate field in the merchant token represent? Is this the date when the device token or merchant token expires and payments cannot be made with it?

PDFKit - beginFindString
I am creating an iOS app that needs to parse the text from a PDF document. I can read the entire PDF document's text using the string property, but if it's a large PDF document, this could cause delays for users. From the documentation, I came across the beginFindString function, which seems to asynchronously, with no return? https://developer.apple.com/documentation/pdfkit/pdfdocument/beginfindstring(_:withoptions:)) Unfortunately I cannot find examples on how to use this function or its intended purpose/functionality, so any guidance would be appreciated. My goal is to read the PDF document one line at a time, searching for newlines ('\n'), then parsing that line as needed. I'm hoping the beginFindString function will be useful.

Live Caller ID doesn't perform caching
I experimented a lot with Live Caller ID when it first appeared with iOS 18 Beta. Now I'm starting to pick it up again and have immediately noticed some detrimental differences between the behavior observed when it was in beta status to how it currently behaves with iOS 18.3. The main difference is caching - if a call is made and data from a live call id lookup displayed on the call screen, then if the call is made again immediately then that data is re-fetched from the server. And it takes a long time too, about 5 or 6 seconds before the data is displayed in the call screen (with the beta it took about 3 seconds). In the data set cache_expiry_minutes is set to 50, yet it's not being honored, there's no caching occurring at all. Yet this did used to occur several months ago when the feature was in beta. What's happened to caching, why is it no longer working when it used to? Another change is there used to be a notification displayed when a call was blocked, this no longer is displayed. Is this an intentional change or a bug?

Slow app launch time
Hello, We are experiencing slow launch time indicators in our performance monitoring tools(Crashlytics/DataDog/Xcode), and trying to understand what is the best approach to reduce it. Currently, cold launch takes ~900ms on iPhone 16 Pro , but ~2s on iPhone 11. Profiling app launch detected that most of the time is spend on loading the libraries. Our app is massive, we use a total of ~40 3rd parties libraries + 10 internal libraries. We enabled the "mergeable libraries" XCode new feature however the app launch is as written above. We also postponed some of the work in didFinishLaunch, which help a bit... But maybe we are trying to achieve the impossible? Could it be that large apps just can't reach the golden 500ms goal? Currently we are trying to create an "umbrella" library for all the third parties in order to force them to become part of the mergeable libraries. We would like to know if, are we on the right track?

Using Storekit development, unsubscribe and resubscribe callback problem
The app subscription function uses StoreKit. After canceling the subscription, I try to subscribe again and get the following error. I remember it was working fine before iOS 18 was released. { NSLocalizedDescription = "\U53d1\U751f\U672a\U77e5\U9519\U8bef"; NSUnderlyingError = "Error Domain=ASDErrorDomain Code=825 "(null)""; } Hope you can help me solve this problem as soon as possible. Thanks

Generating ephemeralPublicKey for in-app provisioning
I am developing an app to add Discover cards to Apple Wallet. Unlike Visa, MasterCard, etc., Discover does not have APIs that return activationData, encryptedPassData and ephemeralPublicKey for a given card, so I have created a backend server to handle this. In my server, I am unsure how to generate the ephemeralPublicKey. Do I need to use the merchant certificate? If so, how do I use it to generate the ephemeralPublicKey? I would appreciate it if someone could provide me with a step-by-step guide on how to generate ephemeralPublicKey for provisioning a card.

WeatherKit Swift API -metadata reportedTime
Hi there, I am using WeatherKit to display weather forecast information in an app. I would like to include some information about when the weather forecast was issued for my users to see. This information is included in the response Metadata as documented in the WeatherKit REST API docs: https://developer.apple.com/documentation/weatherkitrestapi/metadata Specifically there is a “reportedTime” property which I would like to use here. However I am consuming WeatherKit via the Swift API, I don’t see this property available via the Swift APIs. How can I access the reportedTime property via the WeatherKit Swift APIs? Or is it not exposed via the Swift APIs?

What are the criteria for CLVisit in CoreLocation?
There is no official documentation specifying the exact criteria for determining a CLVisit. For example, if a user starts at a target location, will the following method be called? func locationManager(_ manager: CLLocationManager, didVisit visit: CLVisit) This did not work during my testing. It was only successfully triggered when starting from a distant location and arriving at the target point. It would be helpful to know the exact conditions, such as how long a user must stay at a location for it to be considered a visit. Are there any specific thresholds (e.g., minimum duration, distance moved) that determine when this method is triggered?

How to Archive iMessages via API with User Authorization Workflow?
I’m working on a solution to archive iMessages by using an API or similar mechanism. Here’s the desired workflow: The user provides their phone number to initiate the archiving process. They receive a text message with a URL link. Clicking on the link authorizes the archiving of their iMessages. Once authorized, their text messages are archived. So far, I’ve researched third-party services and APIs but haven’t found any that offer this capability directly for iMessages. Questions: Are there any APIs or frameworks (Apple or third-party) that support accessing and archiving iMessages programmatically?

repeat subscription
After the user initiates the subscription payment, the SDK returns an error type: user cancels. When the user initiates the payment again, Apple will deduct the payment twice and successfully deduct the previously cancelled SKU. This is a recent occurrence with a large amount of data, and the app has not been upgraded in any way. We need to seek help. Thank you

Location Push Service Extension in Limbo
Hi everyone, I submitted a request for the Location Push Service Extension entitlement back in November. I received an acknowledgment email from Apple confirming they had received my request, but I never heard back. Assuming the November request might have been lost in the shuffle, I submitted another request in January. It's been a week since then, and I still haven’t received any response. To follow up, I contacted Apple Support with my case number. Unfortunately, it seems they didn’t review the case properly, as the support assistant just sent me generic links about what to do when an app is rejected—which doesn’t apply here. Has anyone else experienced similar delays with this entitlement? Could there be specific reasons for such delays? Any tips on how to escalate this or get it addressed effectively would be greatly appreciated. Thank you in advance for your help!

Critical SKAdNetwork Attribution
Subject/Title: Critical SKAdNetwork Attribution Failures (Bug Type: 237, Failure Type: 1201 in ASDErrorDomain) Issue Summary We are encountering repeated SKAdNetwork attribution failures (failureType: 1201 in ASDErrorDomain) for ad impression events processed through the ad network mj797d8u6f.skadnetwork. These failures are causing significant revenue losses, as ad impressions are not being properly attributed to installs. The issue occurs across multiple campaigns and involves both SKAdNetwork API 3.0 and 4.0, suggesting a systemic problem with attribution validation or network communication. This problem is critical as it disrupts advertisers’ ability to track conversions, optimize campaigns, and allocate budgets effectively. Technical Details Key Logs: Below are anonymized samples of the failed SKAdNetwork events: Log Sample 1 (Failure): { "bug_type": "237", "timestamp": "2025-01-07 22:49:15.00 -0500", "os_version": "iPhone OS 18.2.1 (22C161)", "roots_installed": 0, "incident_id": "78523BD9-1F58-4738-B526-8A8A63203214" } { "advertisementStoryId": "3D2E7EBB-1A57-4DF8-9375-2C465F423038", "apiVersion": "3.0", "eventType": "adImpression", "resultType": "finalized", "anonymous": true, "failureType": 1201, "failureDomain": "ASDErrorDomain", "clientEventId": "0F456623-584F-4913-BBD3-C3FD1219D104", "os": "iOS", "topic": "xp_amp_skad_perf", "adType": "app", "adNetworkId": "mj797d8u6f.skadnetwork", "eventTime": 1736305200000, "osBuildNumber": "22C161", "hardwareFamily": "iPhone", "api": "SKAdNetwork" } Log Sample 2 (Failure): { "bug_type": "237", "timestamp": "2025-01-07 22:49:15.00 -0500", "os_version": "iPhone OS 18.2.1 (22C161)", "roots_installed": 0, "incident_id": "0CBF612D-F0D9-449E-A34E-DE2DB92BEC0D" } { "advertisementStoryId": "946E568C-D2C1-478F-BFF3-4996C48F9B39", "apiVersion": "3.0", "eventType": "adImpression", "resultType": "finalized", "anonymous": true, "failureType": 1201, "failureDomain": "ASDErrorDomain", "clientEventId": "1A3D48FB-4452-4FD8-BB25-1195470A53DC", "os": "iOS", "topic": "xp_amp_skad_perf", "adType": "app", "adNetworkId": "mj797d8u6f.skadnetwork", "eventTime": 1736298000000, "osBuildNumber": "22C161", "hardwareFamily": "iPhone", "api": "SKAdNetwork" } Log Sample 3 (Success Example for Comparison): { "bug_type": "237", "timestamp": "2025-01-07 22:49:15.00 -0500", "os_version": "iPhone OS 18.2.1 (22C161)", "roots_installed": 0, "incident_id": "BFEAC86B-8195-4DB0-96FF-2028107256AD" } { "advertisementStoryId": "946E568C-D2C1-478F-BFF3-4996C48F9B39", "apiVersion": "3.0", "eventType": "adImpression", "resultType": "finalized", "anonymous": true, "clientEventId": "F6265488-E0FB-448A-A406-3F7254BCA9D7", "os": "iOS", "topic": "xp_amp_skad_perf", "adType": "app", "adNetworkId": "mj797d8u6f.skadnetwork", "eventTime": 1736294400000, "osBuildNumber": "22C161", "hardwareFamily": "iPhone", "api": "SKAdNetwork" } Failure Details: Failure Type: 1201 Failure Domain: ASDErrorDomain Ad Network ID: mj797d8u6f.skadnetwork API Versions Affected: 3.0, 4.0 Timeframe of Failures: All logs occur within 2025-01-07 22:00:00 UTC to 23:00:00 UTC. Environment: OS Version: iOS 18.2.1 (Build 22C161). Device Type: iPhone (hardwareFamily: iPhone). App Configuration: Includes the ad network ID in the Info.plist under SKAdNetworkItems. Impact Details Financial Loss: Based on failure rates, we estimate $20–$65/day per advertiser for small campaigns and $75–$375/day per advertiser for larger campaigns. If 100 advertisers are affected, daily losses range from $2,000–$37,500. Over a week, losses could exceed $70,000 to $262,500 or more. Operational Impact: Advertisers cannot track installs or optimize campaigns, leading to inefficient ad spending and potential budget reallocation to other networks. Damaged trust between advertisers and the ad network. Reputation Risk: Continued failures harm the credibility of the SKAdNetwork framework, critical in a post-ATT (App Tracking Transparency) ecosystem. Steps to Reproduce Serve an ad impression through the ad network mj797d8u6f.skadnetwork. Monitor SKAdNetwork attribution for that impression. Observe repeated failures (failureType: 1201) despite the resultType: finalized status. Recommendations for Investigation Attribution Timeout: Verify if these failures stem from delayed responses or missed attribution windows. Ad Network Configuration: Confirm the ad network’s integration complies with SKAdNetwork API 3.0 and 4.0 requirements. Infrastructure Review: Investigate potential bottlenecks or failures in Apple’s attribution servers (ASDErrorDomain) or communication delays.

Document based SwiftData apps do not autosave
Document based SwiftData apps do not autosave changes to the ModelContext at all. This issue has been around since the first release of this SwiftData feature. In fact, the Apple WWDC sample project (https://developer.apple.com/documentation/swiftui/building-a-document-based-app-using-swiftdata) does not persist any data in its current state, unless one inserts modelContext.save() calls after every data change. I have reported this under the feedback ID FB16503154, as it seemed to me that there is no feedback report about the fundamental issue yet. Other posts related to this problem: https://forums.developer.apple.com/forums/thread/757172 https://forums.developer.apple.com/forums/thread/768906 https://developer.apple.com/forums/thread/764189
