IAP StoreKit2 Can Not Fectch Products
I am currently using StoreKit2 to set up the in-app purchase subscription flow, and I have already configured the subscription products in App Connect. I created a StoreKit Configuration file in Xcode and used it in the scheme. However, after completing the purchase, the transaction.jsonRepresentation data returns a transactionId of 0. After checking the documentation, I found that I need to disable the StoreKit Configuration and enable Sandbox Testing. But after disabling the StoreKit Configuration, I can't retrieve the real product data using Product.products(for: productIds). I can confirm that the ProductId I provided is real and matches the data configured in App Connect. Could you please help me identify the issue? Thank you

UE 5.4 Game Instantly Crash on iOS devices on Testflight
Hi, I'm working on a game for the past few years using first Unreal Engine 4, and now Unreal Engine 5.4.4. I'm experiencingan unusual crash on startup on some devices . The crash is so fast that I'm barely able to see the launching screen sometimes because the app closes itself before that. I got a EXC_CRASH (SIGABRT) so I know that it's a null pointer reference, but I can't quite wrap my head about the cause, I think that's something messed up in the packaging of the app, but here is where I'm blocked, I'm not that accustomed with apple devices. If someone has some advise to give, please, any help will be very valuable. Many thanks. Log : Crash Log on Ipad

Push notifications to api.push.apple.com sometimes fail
We have a case when we send 8 push notifications more or less simultaneously over 1 HTTP 2.0 connection. Using .NET Core 8 Sometimes some of them fail with a strange message: System.Net.Http.HttpRequestException: The response ended prematurely while waiting for the next frame from the server. (ResponseEnded) ---> System.Net.Http.HttpIOException: The response ended prematurely while waiting for the next frame from the server. (ResponseEnded) at System.Net.Http.Http2Connection.ThrowRequestAborted(Exception innerException) at System.Net.Http.Http2Connection.Http2Stream.TryEnsureHeaders() at System.Net.Http.Http2Connection.Http2Stream.ReadResponseHeadersAsync(CancellationToken cancellationToken) at System.Net.Http.Http2Connection.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken) --- End of inner exception stack trace --- at System.Net.Http.Http2Connection.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken) at System.Net.Http.HttpConnectionPool.SendWithVersionDetectionAndRetryAsync(HttpRequestMessage request, Boolean async, Boolean doRequestAuth, CancellationToken cancellationToken) at System.Net.Http.RedirectHandler.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken) at System.Net.Http.DecompressionHandler.SendAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken) at Microsoft.Extensions.Http.Logging.HttpClientLoggerHandler.SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) We noticed that failure is always accompanied with a huge delay (~500ms) comparing to success (~20ms). Also some of the burst messages are sent successfully (sometimes 2-4 of them) What can we do about it?

Message Filtering Extension
I have an app with Message Filtering Extension enabled and I have been experiencing unusual behaviour. When I send messages from local number to local number, the filtering is done correctly, but when I send messages from certain international number to my local number the messages are not filtered. I couldn't find any errors in Console. I see that the normalisation is correct, is there any specifications for SMS from certain countries? Or a reason why Message Filtering is not activated when a SMS is received?

When Using Callkit audio doesn't have permission to work
I am creating a voip app, I am trying to use call kit to answer calls, however audio doesn't seem to work when using callKit when looking at the systems logs I see no server connection when checking background audio state, won't allow background audio! background audio processAllowed = 0 for displayID com.apple.TelephonyUtilities no server connection when checking background audio state, won't allow background audio! background audio processAllowed = 0 for displayID {my app id} I have the plist entries for background ui modes for voip, audio, fetch and background notifications along with the backgrounds modes for Voip, Audio, AirPlay, and Picture in Picture, Background notifications. I am unsure what to do about this, like my reading of the error is I can't use audio cause I am not connected to a server, but like is it any server, Am I suppose to connect to the voip call before setting up audio, I am not sure how to do that.

Resolving URL from bookmark data doesn't automatically mount SMB volume on iOS
On macOS, the Finder allows to connect to a server and store the login credentials. When creating a bookmark to a file on a server and resolving it again, the server is mounted automatically (unless I provide the option URL.BookmarkResolutionOptions.withoutMounting). I just tried connecting to my Mac from my iPad via SMB in the Files app and storing a bookmark to a file on the server, but disconnecting the server and trying to resolve the bookmark throws the error (I translated the English text from Italian): Error Domain=NSFileProviderErrorDomain Code=-2001 "No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"'" UserInfo={NSLocalizedDescription=No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"., NSUnderlyingError=0x302a1a340 {Error Domain=NSFileProviderErrorDomain Code=-2013 "(null) "}} Every time I disconnect and reconnect to the server, selecting the same file returns a different path. The first time I got /private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/WtFD3Ausername/path/to/file.txt The next time WtFD3A changed to EqHc2g and so on. Is it not possible to automatically mount a server when resolving a bookmark on iOS? The following code allows to reproduce the issue: struct ContentView: View { @State private var isPresentingFilePicker = false @AppStorage("bookmarkData") private var bookmarkData: Data? @State private var url: URL? @State private var stale = false @State private var error: Error? var body: some View { VStack { Button("Open") { isPresentingFilePicker = true } if let url = url { Text(url.path) } else if bookmarkData != nil { Text("couldn't resolve bookmark data") } else { Text("no bookmark data") } if stale { Text("bookmark is stale") } if let error = error { Text("\(error)") .foregroundStyle(.red) } } .padding() .fileImporter(isPresented: $isPresentingFilePicker, allowedContentTypes: [.data]) { result in do { let url = try result.get() if url.startAccessingSecurityScopedResource() { bookmarkData = try url.bookmarkData() } } catch { self.error = error } } .onChange(of: bookmarkData, initial: true) { _, bookmarkData in if let bookmarkData = bookmarkData { do { url = try URL(resolvingBookmarkData: bookmarkData, bookmarkDataIsStale: &stale) } catch { self.error = error } } } } }

UDP Broadcast/Multicast Reception Stops for Intervals
Our app receives real-time GPS and aircraft data from devices via UDP broadcast and/or multicast on a WiFi network created by the device. We have identified that the iPhone or iPad will just stop receiving UDP broadcast/multicast data for an interval of time. In general, it appears after roughly every 128KB of data is received. In the attached screenshot from Xcode instruments, you can see the data reception alternating on/off. We have verified with Wireshark that the data is still flowing during that entire time period. And by tracking bytes received the app ultimately receives about 55% of the bytes, which tracks with the Network graph. We have used different approaches to the network code, including GCDAsyncUdpSocket, BSD Sockets, and the Network framework. We've tried it on background threads and the main thread. Tested it on iPads and iPhones. All produce the same result. The data is just never reaching the app code. Any insight on what may be temporarily disabling data reception?

Communicating between app & ui test runner
I'd like to set up a communication mechanism between the Ui test runner and my iOS app. The purpose is to be able to collect some custom performance metrics in addition to standard ones like scrollingAndDecelerationMetric. Let's say we measure some specific intervals in our code using signposts, then serialize the result into a structured payload and report it back to the runner. So, are there any good options for that kind of IPC? The primary concern is running on Simulator. However, since it is not a regular UI test but more a performance UI test, and it is usually recommended to run those on a real device, with release optimizations/flags in place, I wonder if it is feasible to have it for device too.

Receiving 404 Error for APNs Server Notifications When Validating signedPayload
Hi everyone, I'm experiencing an issue with APNs server notifications where I receive a 404 error when trying to validate the signedPayload from Apple's notification. Below is a sanitized version of my code: class ServerNotificationAppleController extends Controller { // URL for StoreKit keys (Sandbox environment) private $storeKitKeysUrl = 'https://api.storekit-sandbox.itunes.apple.com/inApps/v1/keys'; public function handleNotification(Request $request) { \Log::info($request); $signedPayload = $request->input('signedPayload'); if (!$signedPayload) { return response()->json(['error' => 'signedPayload not provided'], 400); } // Step 1: Create your JWT token (token creation logic can be in a separate service) $jwtToken = $this->generateAppleJWT(); // Step 2: Send a request to the StoreKit keys endpoint $response = Http::withHeaders([ 'Authorization' => 'Bearer ' . $jwtToken, ])->get($this->storeKitKeysUrl); Log::info('Apple Keys Status:', ['status' => $response->status()]); Log::info('Apple Keys Body:', ['body' => $response->body()]); if ($response->status() !== 200) { return response()->json(['error' => "Apple public keys couldn't be retrieved"], 401); } $keysData = $response->json(); // Step 3: Validate the signedPayload $validatedPayload = $this->validateSignedPayload($signedPayload, $keysData); if (!$validatedPayload) { return response()->json(['error' => 'Invalid signedPayload'], 400); } // Process the validated data as needed Log::info("Apple Purchase Data:", (array)$validatedPayload); return response()->json(['message' => 'Notification processed successfully'], 200); } private function generateAppleJWT() { // API key details (replace placeholders with actual values) $keyId = config('services.apple.key_id'); // e.g., <YOUR_KEY_ID> $issuerId = config('services.apple.issuer_id'); // e.g., <YOUR_ISSUER_ID> $privateKey = file_get_contents(storage_path(config('services.apple.private_key'))); // Set current UTC time and expiration time (20 minutes later) $nowUtc = Carbon::now('UTC'); $expirationUtc = $nowUtc->copy()->addMinutes(20); // Create the payload with UTC timestamps $payload = [ 'iss' => $issuerId, 'iat' => $nowUtc->timestamp, 'exp' => $expirationUtc->timestamp, 'aud' => 'appstoreconnect-v1', 'bid' => 'com.example.app', // Replace with your Bundle ID if necessary ]; // Generate the JWT token return JWT::encode($payload, $privateKey, 'ES256', $keyId); } private function validateSignedPayload($signedPayload, $keysData) { try { $jwkKeys = JWK::parseKeySet($keysData); return JWT::decode($signedPayload, $jwkKeys, ['RS256']); } catch (\Exception $e) { Log::error("Apple Purchase Validation Error: " . $e->getMessage()); return null; } } } I’m particularly puzzled by the fact that I receive a 404 error when trying to retrieve the public keys from the StoreKit keys endpoint. Has anyone encountered this issue or can provide insight into what might be causing the error? Any help or suggestions would be greatly appreciated. Thanks!

About the problem that DeviceActivityMonitorExtension does not work
I am developing an app that can help users disable selected apps at a specified time, so that users can get away from their phones and enjoy real life. Here is my data structure: extension ActivityModel { @NSManaged public var id: UUID @NSManaged public var name: String @NSManaged public var weeks: Data @NSManaged public var weekDates: Data @NSManaged public var appTokens: Data } Among them, weeks is of [Bool] type, indicating which weeks from Sunday to Saturday are effective; weekDates is of [[Date,Date]] type, indicating the effective time period; appTokens is of Set type, indicating the selected apps。 At the beginning, I will open a main monitor: let deviceActivityCenter = DeviceActivityCenter() do{ try deviceActivityCenter.startMonitoring( DeviceActivityName(activityModel.id), during: DeviceActivitySchedule( intervalStart: DateComponents(hour: 0,minute: 0,second: 0), intervalEnd: DateComponents(hour: 23,minute: 59,second: 59), repeats: true ) ) }catch { return false } Since the time range may be different every day, I will start the sub-monitoring of the day every time the main monitoring starts: override func intervalDidStart(for activity: DeviceActivityName) { super.intervalDidStart(for: activity) if activity.rawValue.hasPrefix("Sub-") { ActivityModelManager.disableApps( Tools.getUUIDFromString(activity.rawValue) ) return } let weekIndex = Calendar.current.component(.weekday, from: .now) let weeks = ActivityModelManager.getWeeks(activity.rawValue) if weeks[weekIndex] { let weekDates = ActivityModelManager.getWeekDates(activity.rawValue) let deviceActivityCenter = DeviceActivityCenter() do{ try deviceActivityCenter.startMonitoring( DeviceActivityName("Sub-" + activityModel.id), during: DeviceActivitySchedule( intervalStart: getHourAndMinute(weekDates[weekIndex][0]), intervalEnd: getHourAndMinute(weekDates[weekIndex][1]), repeats: false ) ) }catch { return } }esle { return } } I will judge whether it is main monitoring or sub monitoring based on the different activity names. When the sub-monitor starts, I will get the bound application and then disable it: static func disableApps(_ id : UUID){ let appTokens = ActivityModelManager.getLimitAppById(id) let name = ManagedSettingsStore.Name(id.uuidString) let store = ManagedSettingsStore(named: name) store.shield.applications = appTokens return } When the child monitoring is finished, I resume the application: static func enableApps(_ id : UUID){ let name = ManagedSettingsStore.Name(id.uuidString) let store = ManagedSettingsStore(named: name) store.shield.applications = [] } The above is my code logic. When using DeviceActivityMonitorExtension, I found the following problems: intervalDidStart may be called multiple times, resulting in several sub-monitors being started. After a period of time, the monitoring is turned off. The static methods enableApps and disableApps are sometimes not called

WeatherKit - missing ForecastHourly field documentation
where can we find documentation on the following fields included in payloads? They're not listed alongside the other fields in the documentation linked below: https://developer.apple.com/documentation/weatherkitrestapi/hourweatherconditions precipitationIntensity snowfallAmount Or if we can get the data type, unit used, and description here that would be great

full disk access granted, but app fails to load file from user folder
i recently upgraded to sequoia, and now, more often than not, when running in the debugger, opening my database causes a hang: When i run outside the debugger, it opens just fine. I suspect it has to do with "full disk access"? but i've given my app full disk access. i've also set Qt and Xcode to have "Allow apps to use developer tools" permissions. as a test i also added my app into that permission group, all to no avail. the path to the DB being opened is in my user's Music folder, and having full disk access gives permission for everything, including things in that folder. confused!

Filtering MMS Messages with Multimedia Content (Images, Videos, etc.)
Hi Apple Developer, I’m working on a message-filtering application and reviewing Apple's documentation on message filtering. The documentation clearly states that MMS messages can be filtered. (https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) When we refer to MMS, it includes images, short videos, and other supported multimedia formats. However, the ILMessageFilterQueryRequest only provides the message body as a String, meaning we can access text and links but not images or other media files. Could you please confirm whether Apple allows third-party applications to access multimedia content sent from unknown numbers? Looking forward to your quick response. Thanks, Rijul Singhal
