Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!

I’m working on a Flutter application that implements subscriptions using in-app purchases (IAP). I currently have two apps under the same developer account: One for staging One for production In App A (staging), I successfully created a monthly subscription with the product ID: rc_1299_monthly However, when I try to create a subscription with the same product ID (rc_1299_monthly) in App B (production), I encounter the following error: "The Product ID you entered is already being used by another subscription." My understanding was that product IDs are scoped per app, but this error suggests there may be account-level constraints. Has anyone encountered this before? Is it required to use unique product IDs across all apps under the same account, or is there a recommended approach for handling staging vs production setups? Any clarification or best practices would be appreciated.

We have been using the purchase date to identify the latest transaction_id for a given original_transaction_id. However, I’ve noticed several cases where an immediate upgrade does not result in a later purchase date—in some instances, it is actually earlier than the previous transaction. Given this inconsistency, would it be more reliable to sort by transaction_id in descending order instead?

Any plans to be able to allow to store Uric Acid (UA) and Ketones readings in Apple Health with HealthKit? There are now many blood test strips in the market that allow to read Glucose, UA and Ketones and currently only Glucose seems to be supported by HealthKit. Thank you

I have two different VersionedSchema accessed via two different and distinct in-memory ModelContainers. However, both schemas have a model named Item. LocalSchema.Item and RemoteSchema.Item have slightly different properties. If I create and save RemoteSchema.Item in one context then I cannot create and save LocalSchema.Item in a different context due to missing origin property. enum LocalSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { @Attribute(.unique) var title: String var created: Date var modified: Date init(title: String, created: Date, modified: Date) { self.title = title self.created = created self.modified = modified } } } enum RemoteSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { var title: String var created: Date var modified: Date var origin: String init(title: String, created: Date, modified: Date, origin: String) { self.title = title self.created = created self.modified = modified self.origin = origin } } } In the above example, saving RemoteSchema.Item will cause LocalSchema.Item to fail. The error message I see is *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSManagedObject 0xa120f3750> setValue:forUndefinedKey:]: the entity Item is not key value coding-compliant for the key "origin".' Test Code @Test func createLocalItemWithManualSave() async throws { let context = ModelContext(try localStore()) let item = LocalSchema.Item(title: "local", created: .now, modified: .now) context.insert(item) try context.save() } @Test func createRemoteItemWithManualSave() async throws { let context = ModelContext(try remoteStore()) let item = RemoteSchema.Item(title: "remote", created: .now, modified: .now, origin: "from space") context.insert(item) try context.save() } func localStore() throws -> ModelContainer { let schema = Schema(versionedSchema: LocalSchema.self) let config = ModelConfiguration("local", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } func remoteStore() throws -> ModelContainer { let schema = Schema(versionedSchema: RemoteSchema.self) let config = ModelConfiguration("remote", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } I have created FB22310365

I’m currently developing an iOS app that relies heavily on location details. I'm using MapKit and MKMapItem as my primary data source, which works perfectly for standard metadata. However, I’ve hit a roadblock: I want to display opening hours inline within my location details, but it seems Apple doesn't expose a public API or property for this in MKMapItem (even though the data is clearly visible in the native Apple Maps app). Since I'm building this as an indie developer/startup, the Google Places API is unfortunately too expensive for my current budget. ⁠Is there any legitimate, native way to get opening hours from Apple that I might have missed? ⁠If not, what are your best practices or recommended indie-friendly alternatives (e.g., Yelp Fusion API, OpenStreetMap, Foursquare)? Any tips on how to handle this elegantly and cost-efficiently would be highly appreciated! Thanks in advance.

I am using Significant Location Change (SLC) monitoring to relaunch my app after it has been terminated. I have implemented SLC in two separate apps installed on the same device, and I would like to understand how the system delivers SLC events in this scenario. Specifically: Will both apps receive the SLC event at the same time, or can there be differences in the timing of delivery? If there are differences, what factors influence when each app receives the event? What criteria or system conditions determine how and when SLC events are delivered to different apps on the same device? Any clarification on the event delivery behavior would be greatly appreciated.

Hi, I want to create a ControlWidget button that acts as a shortcut in the control center open a specific view within my app to show a badge. Problem: I can‘t get it to open my host app. I tried a custom myapp:// protocol - did not work, I tied AppIntent with the openAppWhenRun set to true - did not work and the strange thing is the debugger breakpoint in perform will only get triggered if this is set to false. OpenIntent did not work either even if I use a dummy swift app as host to try it out. What is the current supported way (iOS 18 and 26) to open your app when a static ControlWidget button is clicked, what could I have done wrong / am missing?

When iterating over a CMSensorDataList (which conforms to NSFastEnumeration) returned by CoreMotion's CMSensorRecorder's accelerometerData(from:to:) method, we sometimes see the crash below, with the frame above pointing to the close brace of the for loop iterating over the list. 0 CoreMotion 0x000000019fcf01dc CLInternalGetPinnedLocationAuthorizationState + 423316 1 CoreMotion 0x000000019fcf036b CLInternalGetPinnedLocationAuthorizationState + 423715 2 CoreMotion 0x000000019fcf02cb CLInternalGetPinnedLocationAuthorizationState + 423555 3 CoreMotion 0x000000019fbb8553 CLMotionActivity::isStatic() const + 1751823 It has been incredibly difficult to reproduce. We managed to reproduce a similar crash stack twice in a separate app that misused accelerometerData(from:to:) by providing a from and to Date that were more than 12 hours apart and iterating over the returned data, but it only occurred twice in many hours of testing. We hope to know if this could be a bug in Core Motion or it is definitely in our SDK, or if there is any way to fail gracefully in this scenario.

I am implementing an Unwanted Communication Reporting Extension (IdentityLookupUI) to allow users to report spam messages to our backend. The extension works perfectly in terms of data collection and network reporting (using ILClassificationExtensionNetworkReportDestination). However, I’ve encountered an issue with the message lifecycle: whenever the user taps "Done" and I return a response, the system automatically moves the reported message to the Recently Deleted folder. I want to report the data but keep the message in its current folder (especially when the user classifies it as "Safe"). I have tried varying the ILClassificationAction, but it seems the system ignores the action in favor of "cleaning up" the thread. Example of my current implementation: override func classificationResponse(for request: ILClassificationRequest) -> ILClassificationResponse { // Even when returning .none or .reportNotJunk let action: ILClassificationAction = (self.type == "spam") ? .reportJunk : .none let response = ILClassificationResponse(action: action) response.userInfo = ["type": self.taggedType, "sender": self.sender] return response } My Questions: Is there a specific ILClassificationAction or userInfo key that tells iOS not to move the message? Is this movement a mandatory "post-report cleanup" behavior of the IdentityLookup framework that cannot be overridden? Does anyone know a workaround to report the communication while maintaining its original location in the Messages app?

The following issue has occurred: Push notifications are not being received on certain devices. What could be the possible causes? Push notifications are being sent from our own server, and we are receiving normal responses from APNs. Users have confirmed that notifications are enabled on their devices, and they report no network issues. This problem is occurring for multiple users.

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

According to the release notes for macOS Tahoe 26.4 beta, a warning dialog should appear when launching apps that require Rosetta 2, informing users that these apps will stop working in a future macOS release. However, on my MacBook Air M1 running Tahoe 26.4 Beta 4 (25E5233c), no such warning appears when launching Intel (x86_64) apps. Test case: VLC media player Downloaded from the official VLC website: https://www.videolan.org/vlc/ Selected the Intel 64-bit version (vlc-3.0.21-intel64.dmg) Copied VLC.app to /Applications Code signature verified: Identifier: org.videolan.vlc Format: Mach-O thin (x86_64) Team ID: 75GAHG3SZQ Timestamp: June 2024 Flags: hardened runtime Notarization: accepted (Notarized Developer ID) spctl --assess --verbose /Applications/VLC.app → accepted, source=Notarized Developer ID Launched VLC.app — no Rosetta deprecation warning appeared System log findings: The following entry was repeated many times in the system log: Sandbox: oahd-helper deny(1) file-read-data /usr/libexec/rosetta/oahd-helper This suggests that oahd-helper is being blocked by the Sandbox from reading its own binary, which may be preventing the warning dialog from appearing. My questions: Is this a known bug in Beta 4? Does the absence of a warning mean the app will continue to work in macOS 28 and beyond? Should I file a Feedback report for this? Any insights would be appreciated. Thank you.

Hi I’m working on an app Called Wiux ( already on Android ) but one of my clients has a company with all iPhones so I need to develop the app for iOS, but I’m facing A huge wall, it’s an proactive wifi user experience monitor for distributed networks and the idea is that the app its sending every minute info about connectivity RSSI, which network , if is 2,4ghz or 5ghz channel used and device usage cpu ram etc but I find that is no getRSSI ( and I really need that data ) but some aps like iWifi or WiFi probe has that data and it works I check the reads with a phisical probe and my app on android and values match. i think maybe with NEHotspotHelper I could get the data but I don’t know how to ask to use it or if exist a dependency for quality monitoring that allows me to access that thow o info. ( And probably in the near future I face the same problem with LTE ( that I’m also monitoring with the app on Android and I think is going to be a problem on iOS )

Original discussion pre iOS 26 Our app uses Auth0 with HTTPS callback, we've found the issue where AASA file is not ready immediately when app is initially launched, which is the exact issue from the above link. The issue seems mostly fixed on later versions on iOS 18, however, we are seeing some indications of a regression on iOS 26. Here's some measurement over the last week. | Platform | iOS 18 | iOS 26 | |---------------|----------|--------| | Adoption rate | 55% | 45% | | Issue seen | 1 | 5 | | Recover? | Yes | No | This only 1 iOS 18 instance was able to recover after 1 second after the first try, however, all iOS 26 instances were not able to recover in couple tens of seconds and less than 1 minute, the user eventually gave up. Is there a way to force app to update AASA file? Are there some iOS setting (like using a VPN) that could potentially downgrade the AASA fetch?

Hi everyone, we’ve been waiting since May 30 for our Tap to Pay on iPhone entitlement to be enabled for distribution, but it’s still only active for development (Case‑ID: 14485444). We submitted: A new video recorded from an external device showing the full checkout flow Updated merchant education using the ProximityReaderDiscovery.Topic.payment(.howToTap) API, as suggested by Apple The team initially said the education was compliant, then said it wasn’t. We fixed everything, sent the updated materials, and haven’t heard back in days. We can’t even upload the app to TestFlight because of this error: Profile doesn't include the com.apple.developer.proximity-reader.payment.acceptance entitlement It’s now been almost a month and a half, and this delay is becoming critical. It’s blocking both internal testing and our production release. We’d really appreciate clarity on: Do we need to submit another request via the form? Or is it enough to reply to the existing email thread? Also, are there any direct contacts or escalation paths we can use? Any help or guidance appreciated

https://developer.apple.com/documentation/widgetkit/keeping-a-widget-up-to-date lists a number of exception including "The widget’s containing app has an active audio or navigation session." https://developer.apple.com/videos/play/wwdc2021/10048/ mentions: "However, there are a few situational exceptions that will make these reloads occur both immediately and budget-free. These are when your container app is foreground to the user or when your app is participating in a user session, like Navigation or Now Playing audio." Does an active workout session in a watchOS app count as "your app is participating in a user session", so calls to WidgetCenter.shared.reloadTimelines(ofKind:) are budget-free?

I configured my app to show a Live Activity when an alarm rings using AlarmKit. However, if I dismiss the Live Activity by tapping somewhere other than the X button, and then long-press the Dynamic Island, a new Live Activity appears that is long but contains no information. Currently, the only way I can remove this empty Live Activity is to press the X button while the alarm is in the snooze state. Pressing the X button on the initial alarm does not remove it. Is there any way to prevent this behavior or properly handle / clean up this empty Live Activity?

We are developing a watchOS application that records long audio sessions and uploads them to our backend in chunks (~5 MB each) using pre-signed URLs and URLSession background upload. Current behavior: While audio recording is active, uploads continue successfully even when the app is in the background. Once the recording stops, if multiple chunks (e.g., 10+) are still pending, the remaining uploads do not proceed in the background and appear to be suspended. We attempted to use WKExtendedRuntimeSession (mindfulness type) to allow sufficient time to enqueue background upload tasks, but the session is invalidated when the app goes to the background (e.g., wrist down or app inactive), which prevents reliable scheduling of uploads. Additionally, we added the entitlement: com.apple.developer.extended-runtime-session (mindfulness) in the Watch app entitlements file, but Xcode automatic signing fails with: “Provisioning profile does not include the com.apple.developer.extended-runtime-session entitlement.” It appears that the provisioning profile is not being updated to include this entitlement. Our questions: Is WKExtendedRuntimeSession (mindfulness) expected to support scheduling background URLSession uploads after the app goes to background? How should we reliably complete pending background uploads on watchOS after a long recording session ends? Is there any additional entitlement or recommended approach for this use case? Why is the extended runtime entitlement not being applied to the provisioning profile despite being added in the entitlements file? We are aiming to follow Apple-recommended practices for long-running tasks and background uploads on watchOS. Any guidance would be greatly appreciated.
