Platform: iOS 26 (23E254) Xcode: 26.0 Reproduces on: Debug builds AND TestFlight Summary: I'm using Apple-Hosted Managed Background Assets with on-demand download policy. The .aar archives download successfully (correct file size, status = downloaded), but the contents are never extracted into the asset pack namespace. AssetPackManager.shared.contents(at:) returns fileNotFound for all path variants, and url(for: FilePath(".")) returns a URL that exists but contains zero children. Root Cause from Sysdiagnose: The backgroundassets.user daemon logs reveal this error on every download attempt: A bundle record couldn't be looked up for the application identifier "AtlasDrift.SnapTrail": Error Domain=NSOSStatusErrorDomain Code=-10814 "(null)" UserInfo={_LSFile=LSBindingEvaluator.mm, _LSLine=1973, _LSFunction=runEvaluator} Error code -10814 is kLSApplicationNotFoundErr. The BA daemon downloads the .aar blob, then attempts to find the app bundle via LaunchServices to locate the extension for extraction — but the LS lookup fails.

Is the daemon's LaunchServices integration known to be broken in this seed? Is there anything about the bundle identifier format or provisioning profile setup that could cause the BA daemon's LS lookup to fail, even though the app installs and runs fine otherwise? Are there any additional Info.plist keys or entitlements beyond what's documented that might be required for the daemon to locate the app bundle? Any guidance would be appreciated. I've filed a Feedback report with the full sysdiagnose attached.

MapKit offers showsTraffic: Bool, which is great for displaying live traffic data on the map. However, MapPolyline sits above it, which makes it quite useless. Is this the expected behaviour?

I submitted a Family Controls Framework Entitlement request on April 16, 2026 for my iOS app (Team ID: U3BVGVPCEH). After 11 days, the request still shows "Submitted" with no status update or email communication. I submitted two additional requests on April 20 and April 23 thinking the first had failed (no confirmation email was ever received). All three show "Submitted": J5DLD62PNZ — April 16 VV8B272DHZ — April 20 D362NT677B — April 23 I also opened a Developer Support ticket on April 23 with no response yet. Can anyone help me a bit? I cannot distribute my app by Testflight and I need it for my PhD.

I'm trying to distribute one-time use offer codes for a non-consumable IAP, but every redemption attempt fails at the App Store with the error: Unable to Purchase This promotional offer is not available. My setup: the app is in Ready for Distribution state, the IAP is Non-Consumable and Approved, and the offer is a Free one-time use offer available in all 175 territories. I generated a batch of 500 production codes which are active and were created more than 24 hours ago. I've already ruled out the usual suspects: the app is installed from the public App Store (not TestFlight), the test Apple IDs have never purchased this IAP before, the storefront is included in the offer's territories, and the IAP works correctly when purchased at regular price. The error reproduces across multiple users, devices, and Apple IDs, and each failing code is still unredeemed. Has anyone successfully shipped non-consumable offer codes since the October 2025 rollout? Thanks!

Heyy, I'm building a music tracking app that logs a user's Apple Music plays to build a personal weekly chart. The core mechanic depends on accurately counting how many times a user plays each track. My current implementation uses MPMusicPlayerController.systemMusicPlayer with beginGeneratingPlaybackNotifications() and observes MPMusicPlayerControllerNowPlayingItemDidChange. This works well when the app is in the foreground or recently backgrounded, but notifications stop firing once iOS suspends the app. To get around this I've implemented: applicationDidBecomeActive - restarts the monitor and logs the currently playing track on every foreground Background fetch (performFetchWithCompletionHandler) - periodically wakes the app to log what's playing. This gives some coverage but misses plays that happen between background fetch intervals or when the user hasn't opened the app in a while. The result is an inaccurate play count which undermines the core feature. My questions: Is there a supported entitlement or capability that would allow an app to receive MPMusicPlayerController playback notifications while suspended? Is MusicKit or MediaPlayer the recommended framework for this use case, or is there a better API I'm not aware of? Are there any supported background modes that would keep playback notification delivery alive without requiring the app to be a full audio player? I've looked at MusicRecentlyPlayedRequest but it only returns the last 25 items with no play counts, so it can't tell me a track was played 10 times vs once. Any guidance on the right approach here would be really appreciated.

Hi, Overview: I get the following error when trying to save / read from SwiftData It happens when I try to save color to SwiftData (code below) Error 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release Questions How can I resolve the error? I am not directly using data, I am using just Float values, swift types. Why am I getting this error? Is there a way to add a breakpoint to stop at the exact type causing the error? (Symbolic breakpoint doesn't seem to help) Or is the below code ok and not responsible for the error? Code import SwiftUI nonisolated struct ColorRepresentation: Codable { let red: Float let green: Float let blue: Float let opacity: Float init(colorResolved: Color.Resolved) { red = colorResolved.red green = colorResolved.green blue = colorResolved.blue opacity = colorResolved.opacity } func color() throws -> Color { Color( red: Double(red), green: Double(green), blue: Double(blue), opacity: Double(opacity) ) } } extension ColorRepresentation: Equatable {}

Hello, with macOS' and iOS' recent updates (26.4.x), Handoff in my app appears to have become dysfunctional, as I receive the following message in the logs: getContinuationStreamsWithCompletionHandler(), inputStream=(null) outputStream=(null) error=Error Domain=NSPOSIXErrorDomain Code=94 "Bad message" UserInfo={NSLocalizedDescription=Could not set up internal streams} It ONLY works: From a Mac with 15.x to other Macs or iOS devices (on 26.4.x).

Now, is it my app, or the OS? Thank you kindly, – Matthias

Hi, Quick question on AlarmKit (iOS 26): is there any way to disable the vibration/haptics that play alongside the alarm sound? I'm building a gentle wake-up alarm and I'd like sound-only behavior. From what I can see, AlertConfiguration.AlertSound only lets me customize the audio (.default or .named(_:)). There doesn't seem to be a haptic-related property on AlertConfiguration or anywhere else in the alarm configuration chain. Is this a current limitation, or am I missing something? If it's a limitation, I'll file a Feedback Assistant request and post the FB number here. Thanks!

When use Q-encoded to handle non-ASCII characters, if raw characters start with non-ASCII, we will get encoded like '=?UTF-8?Q?=XX=XX?='. IOS(>26) Mail App may think the first '?=' end of the '=?UTF-8?Q?=' is then end flag, so show incorrectly.

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.

Hi, We are seeing a reproducible issue when presenting SKStoreProductViewController in our production app context. For a quick summary, presenting and dismissing SKStoreProductViewController on iOS 15/16 can leave our app in a visually corrupted state (black/empty/orphaned-looking UI). On iOS 18/26 (presumably every iOS version in between), the same flow works correctly. What we verified dealloc is not called for our affected view controllers. During StoreKit lifecycle, VC hierarchy is logically valid: window.rootViewController remains stable. presented chain remains expected. SKStoreProductViewController becomes top-presented and dismisses normally as logged in the delegate. In the xcode view hieararchy, only the UITransitionView and UIDropShadowView are present. Our app content VCs are no longer attached to the visible hierarchy. This is the code we used: SKStoreProductViewController *storeVC = [SKStoreProductViewController new]; storeVC.delegate = self; [storeVC loadProductWithParameters:@{ SKStoreProductParameterITunesItemIdentifier: @(APP_ID) } completionBlock:^(BOOL result, NSError *error) { if (result) { [presenter presentViewController:storeVC animated:YES completion:nil]; } }]; -- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController { [viewController dismissViewControllerAnimated:YES completion:nil]; } We also observed that presenting SKStoreProductViewController appears to trigger memory-intensive behavior in this runtime context. Shortly after presentation, UIApplicationDidReceiveMemoryWarningNotification is frequently emitted on affected OS versions. However, even when this happens, our VC ownership remains intact (dealloc not called, root/presented chain still valid), while the visible UI and View Hiearchy is left with just the UIWindowScene. Moreover, to verify and confirm that this is an OS issue and not a hardware issue. We also tried using 2 iPhone 12 devices, one running on iOS 16 and one on iOS 18. The iOS 18 one works flawlessly but the iOS 16 device produces the same behaviour Is this a known StoreKit/UIKit issue on iOS 15/16/17? Any recommended mitigation or perhaps alternatives to using SKStoreProductViewController on these OS versions? Thanks.

I’m using SwiftData with CloudKit and running into an issue during initial sync on a fresh device. I’m importing a small set of records, some records has images as CKAsset (with about 5 images ~3MB). Records indexes are the default ones for the Dev env. The problem is that the import process never seems to complete. However, if I delete those records that contains the assets from the iCloud Dashboard, the import finishes successfully. Has anyone experienced something similar? What approach would you recommend to handle this without implementing a custom sync layer on top of CloudKit? I am logging remote changes events (NSPersistentStoreRemoteChange): CloudKit import in progress...|2026-04-25 22:18:10| Then I see: Background Task 49 ("CoreData: CloudKit Import"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this. And then the import never ends. Thanks!

Our business interface requests require disabling HTTP(s) proxies.

Hello everyone, my app A now supports iOS Widget C under the same Xcode project. Now I have another app B under this project, and I hope it can also support this Widget C. What should be done? How should the app group be configured? I have found some solutions: for example, add this key under the info.plist corresponding to app B: NSExtension NSExtensionPointIdentifier com.apple.widgetkit-extension NSExtensionPrincipalClass $(PRODUCT_MODULE_NAME).WidgetEntryView However, when I configured it and started running, not only could I not see the support Widget C, but the screen also went black. Thank you all.

Is there any information available on how developers can implement the "Firmware Update Readiness" and/or "Firmware Update Status" characteristics in HomeKit? Many consumer devices support this (showing an "update available" icon), however, there appears to be nothing in the documentation about this characteristic, and it is not listed as an option in the HomeKit Accessory Simulator. Thanks in advance!

Hi there, I’m curious to understand how the system determines which language to use for an app. The system is currently set to en-IN (English - India). My app supports the following languages: en (the default development language) en-GB (United Kingdom) en-IE (Ireland) en-US (United States) When I run the app, the Bundle.main.preferredLanguages returns [„en-GB“, „en“], which causes the app to be set to en-GB. However, when the app doesn’t support the preferred system language, I would expect it to default to the en language. Surprisingly, this is not the case. This behavior is precisely described in Technical Note TN2418. Unfortunately, there’s no explanation provided. Is this behavior related to the CLDR Linguistic Distance? I also attempted to replace the default development language en with en-001 (English - world), but it had no effect.

Hello, I submitted a request for Family Controls (Distribution) approval, and it has now been over 4 days without any update on the status. I understand that review times can vary, but I wanted to check if this delay is expected or if there’s anything I might need to do on my end to help move the process forward. Could anyone from the Apple team or the community provide insight into: Typical processing times for Family Controls distribution requests Whether delays beyond a few days are common Any steps I should take to follow up or expedite the review For reference: Status: Submitted Submission time: April 21, 2026 Any guidance would be greatly appreciated. Thank you!
