I'm seeing a timestamp display issue on Apple Watch Notification Center, and I'd like to confirm whether this is a known watchOS behavior or whether there's a setup mistake on our side. Symptom The same APNs notification displays the correct time on iPhone Notification Center and on the initial Apple Watch banner. After the Watch screen turns off and the user later opens Notification Center on Apple Watch, the same notification may show an incorrect relative timestamp such as "3 hours ago" or even "yesterday". The drift is per-notification and persists for that notification until it's dismissed. iPhone NC always shows the correct time. WhatsApp tested side-by-side on the same iPhone/Watch pair does not show this drift. Setup iOS 26.4.2 on iPhone 16 Pro watchOS 26.4 on Apple Watch Series 10 App with paired Apple Watch A UNNotificationServiceExtension that decrypts E2EE message previews and applies Communication Notification enrichment via INSendMessageIntent and content.updating(from:) Production APNs environment, TestFlight builds No beta software Isolation tests already performed Test mutable-content NSE invoked Drift on Watch NC Minimal APNs (alert + sound only) no no no drift NSE skips content.updating(from:), INInteraction.donate/delete (still calls them as no-op via diagnostic build) yes yes — modifies content drift NSE bypasses ALL Intents/Communication Notification APIs (no INPerson, no INSendMessageIntent, no avatar, no updating(from:)); just modifies title/body/sound/category and returns the mutable copy yes yes — modifies content drift Production-like APNs payload (thread-id, target-content-id, category, sound, badge, custom userInfo) but WITHOUT mutable-content no no no drift Eliminated as causes: content.updating(from:), INSendMessageIntent, INInteraction.donate, INInteraction.delete(with:), INPerson/INPersonHandle (not even constructed in test 3), avatar fetching, thread-id, target-content-id, category, sound, badge, custom userInfo, custom createdAt timestamp, stale Siri/Apple Intelligence history (cleared manually on iPhone and Watch). The pattern The only consistent variable distinguishing the no-drift cases from the drift cases is whether mutable-content: 1 is set on the APNs payload (i.e. whether the UNNotificationServiceExtension is invoked). Once invoked, the extension's behavior with respect to Communication Notifications does not seem to affect the outcome — the drift reproduces even when the NSE only modifies title/body/sound and returns. Questions Is there a known watchOS behavior where notifications processed by a UNNotificationServiceExtension use a different timestamp source on Apple Watch Notification Center after the Watch screen has been turned off and reopened, while the initial Watch banner and iPhone Notification Center show the correct delivery time? Are there specific UNMutableNotificationContent properties or APNs payload flags that should be preserved (or avoided) when returning content from an NSE to keep the Watch NC timestamp consistent with the delivery time? For E2EE messaging apps, is there a recommended pattern to decrypt and return content from an NSE that avoids this drift on watchOS? Happy to provide an anonymized snippet of NotificationService.swift and the APNs payload format if useful. Thanks.

Hello everyone, I'm trying to adopt the new Staged Migrations for Core Data and I keep running into an error that I haven't been able to resolve. The error messages are as follows: warning: Multiple NSEntityDescriptions claim the NSManagedObject subclass 'Movie' so +entity is unable to disambiguate. warning: 'Movie' (0x60000350d6b0) from NSManagedObjectModel (0x60000213a8a0) claims 'Movie'. error: +[Movie entity] Failed to find a unique match for an NSEntityDescription to a managed object subclass This happens for all of my entities when they are added/fetched. Movie is an abstract entity subclass, and it has the error error: +[Movie entity] Failed to find which is unique to the subclass entities, but this occurs for all entities. The NSPersistentContainer is loaded only once, and I set the following option after it's loaded: storeDescription.setOption( [stages], forKey: NSPersistentStoreStagedMigrationManagerOptionKey ) The warnings and errors only appear after I fetch or save to context. It happens regardless of whether the database was migrated or not. In my test project, using the generic NSManagedObject with NSEntityDescription.insertNewObject(forEntityName: "MyEntity", into: context) does not cause the issue. However, using the generic NSManagedObject is not a viable option for my app. Setting the module to "Current Project Module" doesn't change anything, except that it now prints "claims 'MyModule.Show'" in the warnings. I have verified that there are no other entities with the same name or renameIdentifier. Has anyone else encountered this issue, or can offer any suggestions on how to resolve it? Thanks in advance for any help!

When I query, an existing database with over 10,000 records from an Objective C app (i.e. CKQueryOperation) I get only N x 100 records returned where N varies each time between 0 and about 10 (i.e. never more than 1000 records and always an even multiple of 100). When I do a “Query Records” on the CloudKit Dashboard I get a similar number of pages of records downloaded (i.e. 0-10). If I tap “Query Records” multiple times I will get more pages of records until the full 10,000 are downloaded. This had been working fine until recently, both from the app and the Dashboard. There are multiple Record Types in the database. Only one Record Type is erroring. The other Record Types continue to work both from the app and the Dashboard. In particular, the Users Record Type has many many records and they all download to many pages with a single tap of “Query Records”. I have posted this to the Feedback Assistant under FB22358865. Here is my code: NSPredicate *predicate =[NSPredicate predicateWithFormat:@"modificationDate>%@",dateLastSynched]; CKRecordType theRecordName=[NSString stringWithString:@"Notices”]; // I also try this for @“Links” and @“Messages” and @“EventMessages" CKQuery *query = [[CKQuery alloc] initWithRecordType:theRecordName predicate:predicate]; CKQueryOperation *theOperation=[[CKQueryOperation alloc] initWithQuery:query]; [self startAQueryOperation:(CKQueryOperation *)theOperation theName:(NSString *)recordName]; -(void)startAQueryOperation:(CKQueryOperation *)theOperation theName:(NSString *)recordName{ theOperation.recordFetchedBlock=^(CKRecord *theRecord){ NSLog(@"XXXjust downloaded a %@",recordName); }; theOperation.queryCompletionBlock=^(CKQueryCursor *theCursor, NSError *error){ if(error){ NSLog(@"XXXerror %@",error); } if(theCursor){ CKQueryOperation *anotherOperation=[[CKQueryOperation alloc] initWithCursor:theCursor]; [self startAQueryOperation:anotherOperation theName:recordName]; } }; CKDatabase *publicDatabase = [[CKContainer defaultContainer] publicCloudDatabase]; [publicDatabase addOperation:theOperation]; } When I run this code in the app I get no “XXXerror” from the NSLogs. I get the expected number of “XXXjust downloaded a” EventMessages (435) and Messages (594) and Links (15) but I get varying amounts, 100 or 400 or 500 “xxjust downloaded a” for the Notices when I should get 10,118 records. Thinking that 10,000 records is too much, if I alter “dateLastSynched” for Notices I still get only 100 or 200, not the expected number. Note that the number is always a multiple of 100. This seems to be consistent with the typical number of records I get on the CloudKit dashboard each time I tap “Query Records”.

Hello everyone, We are encountering a critical regression introduced in iOS 26.4 that results in permanent workout data loss for users. When invoking HKWorkoutBuilder.finishWorkout(completion:) while the iOS device is locked, the save operation fails completely. However, it fails silently: the completion handler executes but returns both a nil workout and a nil error. Expected Behavior: Before iOS 26.4 finishWorkout resulted in a workout id, and correctly stored the workout data in HealthKit. According to HealthKit data protection documentation, saving data when the device is locked should either succeed (writing to a temporary journal file to be merged upon unlock) or explicitly throw an error such as HKError.Code.errorDatabaseInaccessible. Actual Behavior: Because the framework returns nil for both the object and the error, the application has no way to detect that the save failed. We cannot implement a retry mechanism or queue the save, resulting in silent data loss. Steps to Reproduce: We have built a Minimal Reproducible Example (MRE) that reliably triggers this: Initialize an HKWorkoutBuilder and call beginCollection(withStart:) followed by endCollection(withEnd:). Wrap the finishWorkout call in a short 5-second asynchronous delay, protected by a UIBackgroundTask to prevent app suspension. Lock the physical device during this 5-second window. The finishWorkout completion handler will execute while the device is locked, returning workout == nil and error == nil. Existing Reports: We have filed this via Feedback Assistant (a month ago) and opened a TSI (a week ago), providing the MRE project and a sysdiagnose captured at the time of failure: Feedback ID: FB22396180 TSI Case-ID: 19755043 As we have not yet received a response or a suggested workaround through these official channels, we are reaching out to the community. Has anyone else encountered this silent failure with HKWorkoutBuilder recently? Any insights or escalation help would be greatly appreciated.

Hello there, I am wanting to create a custom FSKit extension, and am trying to get the sample passthrough project running: https://developer.apple.com/documentation/fskit/building-a-passthrough-file-system I have just followed the basic instructions from the tutorial above, so have: Selected my team for the signing certificate (required for FSKit module). Built and run. Enabled "Passthrough file system" under "File System Extensions". Made a test directory to mount to: mkdir ~/test But when I run the mount command, I get the following error: mount -t passthrough ~/Documents ~/test mount: Loading resource: The operation couldn’t be completed. (com.apple.extensionKit.errorDomain error 2.) mount: exec /Library/Filesystems/passthrough.fs/Contents/Resources/mount_passthrough for /Users/xxxxxxxx/test: No such file or directory mount: /Users/xxxxxxxx/test failed with 72 The contents of /Library/Filesystems/ is empty, so I don't know if allowing the extension is meant to add something to this directory or not. Any help would be much appreciated!

According to documentation, the URLSession background tasks continue even when the app is suspended. What is the lifespan of the URLSessionDownloadDelegate object when app is suspended or terminated? Will it get re-created and re-initialize properties when the app re-launches, or will it somehow restore the existing property values? Also, urlSessionDidFinishEvents not getting called, and what do we need to do there with the backgroundCompletionHandler? Any insights are much appreciated. We are getting ready to launch and this is a roadblock. (visionOS26.4) Thank you. @Observable class DownloadManager: NSObject, URLSessionDownloadDelegate { ... let config = URLSessionConfiguration.background(withIdentifier: "TestDL") config.sessionSendsLaunchEvents = true var urlSession = URLSession(configuration: config, delegate: self, delegateQueue: nil) func downloadFiles(... { // initiate multiple file downloads concurrently for url in urlList { let task = urlSession.downloadTask(with: url) task.resume() } } func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) { ... func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didWriteData bytesWritten: Int64, totalBytesWritten: Int64, totalBytesExpectedToWrite: Int64) { ... func urlSession(_: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) { ... // Not getting called ?? // Is this only called when app is suspended/terminated? func urlSessionDidFinishEvents(forBackgroundURLSession session: URLSession) { print("didFinishEvents") Task { @MainActor in //urlSession?.finishTasksAndInvalidate() //urlSession = nil // not sure what to do here: if let appDelegate = UIApplication.shared.delegate as? AppDelegate, let completionHandler = appDelegate.backgroundCompletionHandler { completionHandler() appDelegate.backgroundCompletionHandler = nil } } }

I'm a first time developer, relying heavily on Claude Agent. In my app, I'm using CloudKit to sync data between devices, but after a migration something got corrupted and syncing is no longer working. I'm using SwiftData with NSPersistentCloudKitContainer. I'm using Xcode 26.4.1 on a Mac mini. I'm testing my app on the same Mac mini, running Tahoe 26.4.1 as well as an iPad 12.9 running iPadOS 26.3.1 and an iPhone running iOS 18.7.8. Sync stopped after a cachedTotal property was added to a SwiftData model, which triggered a backfill migration that wrote to all records simultaneously across multiple devices. This was followed by an iCloud sign-out/sign-in on the Mac. Here’s a summary of everything I’ve tried already: Reset All Data on all devices multiple times Deleted and reinstalled the app on all devices Deleted the CloudKit zone twice Force-deleted local SQLite store files to clear change tokens Zone and subscription both appear correct in the dashboard Change token updates when data is written (confirming uploads work) No data propagates to other devices in any direction Uploads appear to succeed (change token changes) but imports never fire on any device. In other words, writes work, reads don’t. Is there a way to fully reset the CloudKit container's production private database for a TestFlight app, or is there a way to diagnose why imports are not firing despite a valid zone and subscription?

Hi, I have installed ubuntu in a virtual machine using attached iso and everything works fine. After installing ubuntu it boots from the hard disk always. If i ever wanted to force the vm to boot from ISO how can i do it? Thanks & Regards

Hello, I’m planning to use MapKit JS for a production web/mobile application and I’m trying to better understand the quota limits and pricing model. From the documentation, I understand that MapKit JS provides a free daily limit of: 250,000 map views 25,000 service calls per Apple Developer Program membership. However, I’m not clear about what exactly happens if these limits are exceeded. My questions: If my application exceeds 250,000 map views or 25,000 service calls in a day, what happens? Will the API simply start returning errors (for example HTTP 429), or will Apple automatically charge for additional usage? Is there an official pricing model for usage above the free quota, or do we need to contact Apple to request higher limits? Are these limits strict daily hard limits that should never be exceeded in production? I’m trying to design the architecture of my application and would like to understand whether we must strictly stay below these limits or whether scaling beyond them is possible. Thank you.

Hello, I have a question similar to this post regarding MapKit JS quota limits. I understand that we can request rate limit increases, but it is not a guaranteed increase. My app is rapidly growing. What if Apple decides to not award the limit increase? Then, the directions service of my app will stop working, which would be catastrophic for my company. I need to know if the rate limit increases are guaranteed. I need to decide early on whether to use MapKit JS or another service on, because the more time that passes, the more entangled my code will get with MapKit JS. Can we get some more information on this?

I want to use Apple maps on a site instead of Google maps. Do i need to enroll as a Apple Developer to get access to the MapKit JS? (100 dollars/year)

I would like to report a persistent Apple Maps data issue affecting the Spanish (Spain) version of Apple Maps, especially in the Balearic Islands. Apple Maps is displaying several official place names incorrectly, including municipalities, towns, neighbourhoods and local geographic names. In some cases, Apple Maps also shows duplicated or non-existent neighbourhoods, or classifies neighbourhoods incorrectly as towns/cities. The problem is not isolated to one place. It affects several areas of the Balearic Islands, particularly Mallorca and Menorca. Some examples include incorrect or outdated forms such as Mahon / Mahón instead of Maó, Ciudadela instead of Ciutadella de Menorca, and other place names that do not match the official names used by Spanish geographic authorities. These names should follow official geographic sources such as the Instituto Geográfico Nacional (IGN) and the official cartographic data of the Balearic Islands. The issue appears specifically in the Spanish (Spain) version of Apple Maps. I have tried to report these errors many times using the built-in “Report an Issue” function in Apple Maps, including official references and screenshots. However, the reports are repeatedly rejected with the same generic response: “The specific change could not be made.” This reporting function does not seem to work properly for different types of map data. It fails not only for official city and town names, but also for neighbourhoods, duplicated or non-existent areas, and POIs. Even when the correction is supported by official geographic sources or clear local evidence, the reports are rejected without a useful explanation or a real review process.

I have a custom-developed USB NCM device for a networking use case. My device is successfully enumerated by macOS at the USB layer, and it issues a USB SET_INTERFACE(altsetting = 1) to enable the NCM layer, but sometimes (about 50% of the time), the Mac then issues a USB SET_INTERFACE(altsetting = 0), which disables the interface. It never issues a SET_INTERFACE(altsetting = 1) command to re-enable it. In Network settings, the device just stays in the "Disconnected" state forever. For context, the NCM specification says that all NCM devices must have two "alternate settings" at the USB interface level. Altsetting 0 is the default "disabled" startup state where no data endpoints are enabled, and altsetting 1 is the "enabled" state where data IN/OUT endpoints are enabled and packets can be transferred. The NCM spec also says that SET_INTERFACE(altsetting=0) can be used by the host to 'reset' the NCM layer of the device back to known settings. I suspect this is what the Mac is trying to do, though it only does it 50% of the time. The remainder of the time, the device stays in altsetting 1 and traffic works just fine. My question is, how can I get to the bottom of why the Mac is sometimes sending the SET_INTERFACE(altsetting=0) command or, if this behavior is usual, why is it not then re-enabling using SET_INTERFACE(altsetting=1) ? "log stream --info --debug" shows no information on this, and the NCM driver is a closed-source kernel extension so I have no visibility of what it's doing and why. I've sniffed the USB bus using a packet analyzer and can't see anything odd there (no timing issues or dropped packets etc). Any tips would be appreciated. I'm on Tahoe 26.4.1. I really don't want to develop a custom driver for this device and would prefer to operate with the native NCM driver.

Hi all, I'm building a coaching app for runners on top of WorkoutKit and would like to confirm a missing API — or learn that I overlooked something. The gap IntervalStep transitions deliver a haptic at T0 of the next step. The available alerts (HeartRateRangeAlert, SpeedRangeAlert, PaceRangeAlert, PowerRangeAlert, CadenceRangeAlert) are reactive — they activate when the measured value leaves the target range, not ahead of a planned step. There is no API for a "pre-roll" haptic at, say, T-15s before a high- effort step. On watchOS today, the only signal arrives exactly at step start. What I checked The WorkoutAlert protocol and concrete types — all metric-driven, no scheduling primitive. IntervalStep initializer — (.work, step: WorkoutStep). No leadTime, warning, countdown, or prepareDuration parameter. CustomWorkout — no per-step pre-roll knob. WorkoutScheduler and the rest of the surface in iOS/watchOS 26.4 SDK. If I missed something obvious, please point me at it. Filed with Apple Feedback ID: FB22708659 Has anyone here found a cleaner workaround, or seen any signal from the WorkoutKit team about pre-roll cues being on the roadmap? Thanks!

I am trying to use BLE in Flutter. I have the following three questions regarding BLE connections: At what point in iOS is the ATT MTU negotiation considered complete after a BLE connection is established? Is there an official callback or state that indicates the completion of the negotiation? Is the value used by iOS during ATT MTU negotiation fixed? If it is fixed, please tell me that value; if it varies, please tell me the conditions under which it varies. If anyone knows the answer, please let me know.

We are observing a regression in iOS 26.4 related to AppIntents, specifically AppEntity + EntityQuery. When using a single AppIntent with a parameter backed by AppEntity and EntityQuery, the query correctly returns multiple entities (e.g. ~50 items). However, in the Shortcuts app UI, only a single item is displayed. This behavior differs from iOS 26.3 and earlier, where all returned entities are correctly displayed in the selection list. This issue significantly impacts dynamic configuration use cases where AppEntity is used to represent server-driven or runtime-generated options.(The screenshots below illustrate the difference in shortcut presentation between iOS 26.4 and earlier versions.)

Both Photos and Lightroom are able to detect when a card reader has been plugged into an iPhone or iPad and a card exists with the correct DCIM format (from a digital camera). I have been unable to find the API that allows an application to do this (except using the standard file import function and making the user navigate to the card). ChatGPT tells me that Photos and Lightroom use a private API that is not made available to normal developers. Does anyone know if this is true - or if not then how to detect that a card is present using Swift?

In the last few weeks 5 users have reported my workout watch app being unable to read health data despite the permissions being enabled in the iPhone Settings app. This has been a common complaint over the years and is usually fixed by disabling the permissions; rebooting both devices; and then enabling them again. This usually nudges iOS into sending the permissions to watchOS. However that procedure doesn't work for these users, all of whom are using watchOS 10.6.2. They are using various versions of iOS 18 or 26 so it seems to be a problem with that version of watchOS, which users are usually limited to because their hardware won't support anything more up to date. It seems that unpairing and re-pairing the watch can fix the problem but not always. I looked around and it seems that other apps are having the same problem: https://www.reddit.com/r/runna/comments/1rhhs2n/runna_wont_start_an_outdoor_run_on_apple_watch/ Does anyone know a way to fix this? My current advice is to repeatedly unpair / re-pair until it works, which isn't really practical! Thanks in advance.

Hi all, I've been observing what appears to be a timing mismatch in how Apple handles Korea trial-to-paid consent, and I wanted to see if other developers are seeing the same thing. Per Korean regulations effective Feb 14, 2025, Apple must obtain explicit user consent before converting a free trial to a paid subscription. Apple handles this via email, push notifications, and an in-app consent option accessible from Settings > Subscriptions. For a 7-day trial in the Republic of Korea storefront, I'm observing: Consent push notifications (Agree to continue your subscription without interruption) start arriving ~1 day after trial redemption, at roughly hourly frequency. However, when the user taps the push and navigates to Settings > Subscriptions, there is no consent option available. The only visible action is "Cancel Free Trial". The consent option only becomes available around day 4 of the trial (i.e., 3 days before renewal, matching Apple's documented messaging cadence [1]). For the first ~3 days, users receive hourly push notifications they cannot act on. The only way to stop them is to cancel the subscription entirely. This is happening across multiple apps in the Korean App Store, so it appears to be a platform-level behavior rather than an app-specific issue. Is anyone else observing this behavior? Any insight from Apple engineers or other developers would be greatly appreciated.

I'm facing a persistent location error on real iOS device: Error Domain=kCLErrorDomain Code=1 The operation couldn’t be completed. (kCLErrorDomain error 1.)
