apple-app-site-association 403
Hi There, hopefully someone can help me here, we weren’t aware but our universal links stopped working sometime last year, as they are not used often on the apps, it wasn’t noticed. We checked all the elements and this is the situation: Our apple-app-site-association file is located at https://ourdomain.com.au/.well-known/apple-app-site-association And it is accessible and can be downloaded. We have Associated Domain services enabled for our app Bundle Id: au.com.identifier.app The Entitlements.plist in our app contains the list of associated domains - the second is the full url, the portal won't let me write it as such as it's not the real address. But links for the first two, …ourdomain.com.au domains don’t work Request https://ourdomain.com.au/.well-known/apple-app-site-association downloads the file and returns status code:403 While checking the availability with https://app-site-association.cdn-apple.com/a/v1/ourdomain.com.au we get the error: ourdomain.com.au: Failed to load resource: the server responded with a status of 404 (Not Found) Going directly to the hosted website: https://app-site-association.cdn-apple.com/a/v1/ourdomain-prod-ourdomainwebsite.azurewebsites.net Returns the json: { "activitycontinuation": { "apps": [ "99ABCD88XXX.au.com.identifier.app", "99ABCD88XXX.au.com.identifier.server.adhoc", "99ABCD88XXX.au.com.identifier.server.dev" ] }, "applinks": { "apps": [], "details": [ { "appID": "99ABCD88XXX.au.com.identifier.app", "paths": [ "/m/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.adhoc", "paths": [ "/mt/" ] }, { "appID": "99ABCD88XXX.au.com.identifier.server.dev", "paths": [ "/md/*" ] } ] } } It appears to be something in the redirect from the url but debugging shows nothing obvious. Has anyone experienced this before? Thanks

Question about including all project classes in ofClasses parameter when using NSKeyedUnarchiver.unarchivedObject(ofClasses:from:)
Hello, I have a question about data deserialization using NSKeyedUnarchiver in iOS SDK development. Current Situation: Previously, we were using the NSKeyedUnarchiver.unarchiveObject(with: Data) function We have changed to using the NSKeyedUnarchiver.unarchivedObject(ofClasses:from:) method to deserialize complex objects stored in UserDefaults We need to include all types in the ofClasses parameter, including Swift primitive types as well as various custom classes and structs within the project Questions: Implementation Approach: Is it correct pattern to include all classes defined in the project in the ofClasses array? Is this approach recommended? Runtime Stability: When using this approach, is there a possibility of runtime crashes? Are there any performance issues? Alternative Methods: If the current approach is not the correct pattern, what alternatives should we consider? Current Code Structure: All model classes conform to the NSSecureCoding protocol We use the requiringSecureCoding: true parameter We use a whitelist approach, explicitly listing only allowed classes I would like to know if this structure is appropriate, or if we should consider a different approach. Thank you.

Defining custom file types
On iOS:When one receives a file of type .pages by email, Mail displays a large Pages icon and tapping on it opens Pages. (A long-press brings up the more complicated Actions screen).When one receives a file of type .vcf by email, Mail displays a large Contacts icon and tapping on it opens Contacts. (A long-press brings up the more complicated Actions screen).I have my own custom file type, .ripf, and I want to have the same behaviour because that is what my users will expect. Accordingly, in my app's Info.plist I have a CFBundleDocumentTypes dictionary providing a one-element LSItemContentTypes array referring to the name 'com.universalis.ripcard', and a UTExportedTypeDeclarations dictionary associating the UTTypeIdentifier 'com.universalis.ripcard' with a public.filename-extension 'ripf' and a public.mime-type 'text/vnd.universalis.ripcard'. All the other entries in those two dictionaries are present and correct as far as I can tell. Both CFBundleDocumentTypes[0].CFBundleTypeIconFiles and UTExportedTypeDeclarations[0].UTTypeIconFiles contain a list of icon files for the file type.(That rather long paragraph is to avoid boring people by including the entire Info.plist!)Some things do work..ripf files received via AirDrop bring up a suitable "Open with..." message which mentions my app, and tapping the message opens the app..ripf files received as an email attachment display as an icon. But it is the app's icon and not the icon of the file type.BUTTapping on a received file's icon does not open the app, but only opens the generic Actions screen, offering Message, Mail, WhatsApp, Notes, and only then (after the user has scrolled sideways) "Copy to..." my app.Now, the whole apparatus of CFBundleDocumentTypes and UTExportedTypeDeclarations is obscure and under-documented, and indeed the main documenation for the latter has a big warning at the top saying that it is obsolete and not being updated. That doesn't matter so much. What I need to know is:(Less important): How do I get the right file icon?(More important): How do I get my app to open when the icon is tapped, as Pages and Contacts do? There must be a way – unless special cases for those two apps are wired into iOS itself.

URLComponents bug in 18.x
Prior to 18.x, this has worked for years. However, if a port is included, the behavior in 18.x is to return "///some/path". In all previous versions it correctly returns "/some/path". Is this a bug, or documented change we missed? func relativeURLString(for urlString: String) -> String? { guard var components = URLComponents(string: urlString) else { return nil } components.host = nil components.scheme = nil // WE FOUND IF YOU NIL THE PORT BEFORE HOST AND SCHEME, IT WORKS components.port = nil return components.string }

Translation framework error.
Hello everyone. I use Translation Framework in my application. During development everything was fine, Translation framework worked well, but after two or three days of using the production version (that was published in AppStore and available for others also!) - my application stopped working. Translation framework gives errors: Error sending 1 paragraphs Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Failed to translate input 0; returning error: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Received unbridged NSError to API, converting to .internalError: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Once again - it worked when I developed it, it was released on the AppStore, and suddenly it stopped working!

WeatherKit API inaccessible for some users
Hi All, I’m puzzled by this issue: my app uses WeatherKit to fetch hourly UV-index and temperature forecasts. The same build, running on the latest iOS, succeeds on most devices but consistently fails on a few. Strangely, the paired Apple Watch version retrieves the data without problems. Could WeatherKit be applying per-user throttling? Any insight would be greatly appreciated.

Non Optional AppIntent Param
After building my app with Xcode 16 beta 6 I'm getting this warning in my AppIntents. Encountered a non-optional type for parameter: computer. Conformance to the following AppIntent protocols requires all parameter types to be optional: AppIntents.WidgetConfigurationIntent, AppIntents.ControlConfigurationIntent The intent looks something like this struct WakeUp: AppIntent, WidgetConfigurationIntent, PredictableIntent { @Parameter(title: "intent.param.computer", requestValueDialog:"intent.param.request_dialog.computer") var computer: ComputerEntity init(computer: ComputerEntity) { self.computer = computer } init() { } public static var parameterSummary: some ParameterSummary { Summary("Wake Up \(\.$computer)") } static var predictionConfiguration: some IntentPredictionConfiguration { IntentPrediction(parameters: (\.$computer)) { computer in DisplayRepresentation( title: "Wake Up \(computer)" ) } } @MainActor func perform() async throws -> some IntentResult & ProvidesDialog { } } According to the docs though specifying optional is how we say if the value is required or not. https://developer.apple.com/documentation/appintents/adding-parameters-to-an-app-intent#Make-a-parameter-optional-or-required So is this warning accurate? If so, how do I specify that a parameter is required by the intent now?

ExtensionFoundation on iOS 26
Hi, I'm trying to add an extension to my app on iOS 26. I've followed the instructions on https://developer.apple.com/documentation/extensionfoundation/adding-support-for-app-extensions-to-your-app and made it as far as being able to launch the extension: let monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .localWebServerExtension) currentIdentity = monitor.identities.first if let currentIdentity = currentIdentity { let myConfig = AppExtensionProcess.Configuration(appExtensionIdentity: currentIdentity, onInterruption: { NSLog("extension was terminated") }) myProcess = try await AppExtensionProcess(configuration: myConfig) myConnection = try myProcess?.makeXPCConnection() } None of these calls throw, and when I examine myProcess from inside that code, it seems to be normal (there's a pid, for example). Yet the code inside my extension seems to not be executed: breakpoints are not triggered, NSLog() calls do not appear on the console. The onInterruption() callback is also not triggered, or at least it does not appear on the console either. I've probably missed something obvious, but what could it be?

Issue regarding universal links
Hello, we are experiencing an issue that is not systematic regarding universal links on our application. In some cases, after the application is installed, the universal links do not open the application but instead open in Safari. We have conducted tests on several devices and with the same link. In some cases, the links open the application after installation, and in other cases, they open in Safari. I should mention that in all test cases, we did not force the opening via the menu accessible through a long press on the link. We performed sysdiagnose in the different cases and we observed the same configuration for the universal links in the swcutil_show.txt file: User Approval: unspecified Site/Fmwk Approval: approved At this stage, I do not think the problem comes from our application or the configuration of the apple-app-site-association file. Is this a known issue? Is there anything we can do on our side to work around it ?

About 0xBAADCA11 error
I am developing "local push" VoIP application. I have a question about issues I found while testing this app. After repeating a test for 24 hours in which a incoming call followed by an immediate disconnect 0.1 seconds later, the iPhone of incommig call side encountered a 0xBAADCA11 error, causing iOS to force-close the app. (The incidence is low, occurring three times in 17280 times incoming call(24 hours.)) This problem found on iOS17.6.1 (iPhone11Pro). When the same test was performed on iOS18.2 (iPhoneSE3), the problem did not occur. Did iOS take something measures against the 0xBAADCA11 error between iOS17.6.1 and iOS18.2? If yes, I want to encourage customers to upgrade to the latest iOS version, please tell me about it? ※I have attached an ips files and sysdiagnose file of the 0xBAADCA11 error occurring. (please refer sysdiagnose also if you need.)

unifiedContacts identifier vs contactRelations identifier
The documentation specifies that when Contacts framework returns unified contacts that each fetched unified contact object (CNContact) has its own unique identifier that’s different from any individual contact’s identifier in the set of linked contacts and that when refetching a unified contact, that this identifier should be used. There is also an analogous identifier within the list of contactRelations, but each of these don't seem to corespondent to the unified contacts. For example, is a new contact (Sheryl Zakroff) is created in the simulator Contacts and their spouse is set to Hank Zakroff. However, the GUID created for the contactRelations identifier does not correlate to the original Hank Zakroff GUID and cannot be searched. Is this a bug or what is the indent of the contactRelations identifier? Here's a debug output of walking the unifiedContacts: Name: Hank Zakroff 2E73EE73-C03F-4D5F-B1E8-44E85A70F170 - Other : (555) 766-4823 - Other : (707) 555-1854 Name: David Taylor E94CD15C-7964-4A9B-8AC4-10D7CFB791FD - Other : 555-610-6679 Name: Sheryl Zakroff DE783BC8-7917-4138-93F6-3AF0FD4CE083 - Other : (707) 555-1854 - Spouse: <CNContactRelation: 0x60000000dd60: name=Hank M. Zakroff> - 534B467D-CA00-46D3-897C-16EEA782C9CF - Looking for ["534B467D-CA00-46D3-897C-16EEA782C9CF"] []

iOS Message Filter Extension - deferQueryRequestToNetwork(completion:) error
iOS Message Filter Extension - deferQueryRequestToNetwork(completion:) error I made a test app using the iOS App template and added a target using the Message Filter Extension template which invokes deferQueryRequestToNetwork(completion:) when receiving an SMS. The app and the extension have same "Associated Domains Capabilities" with "messagefilter" pointing to a server which receives query requests and returns proper responses. The extension has the "ILMessageFilterExtensionNetworkURL" key in Info.plist file which specifies the server URL. deferQueryRequestToNetwork(completion:) throws a com.apple.calls.messagefilter error which reads "Extension's containing app (appID ) unauthorized to defer requests to host "

Live Caller ID: Multiple userIdentifier values for same device - Expected behavior?
Hello! We're currently testing Live Caller ID implementation and noticed an issue with userIdentifier values in our database. Initially, we expected to have approximately 100 records (one per user), but the database grew to about 10,000 evaluationKey entries. Upon investigation, we discovered that the userIdentifier (extracted from "User-Identifier" header) for the same device remains constant throughout a day but changes after a few days. We store these evaluation keys using a composite key pattern "userIdentifier/configHash". All these entries have the same configHash but different userIdentifier values. This behavior leads to unnecessary database growth as new entries are created for the same users with different userIdentifier values. Could you please clarify: Is this the expected behavior for userIdentifier to change over time? If yes, is there a specific TTL (time-to-live) for userIdentifier? If this is not intended, could this be a potential iOS bug? This information would help us optimize our database storage and implement proper cleanup procedures. Thank you for your assistance!

CardSession.Error.maxSessionDurationReached not thrown on iOS 26
Hello, I have an app that emulates an NFC card using NFC HCE. Since yesterday I saw an increasing number of crashes on iOS 26 only, which wasn't there before. From what I can see, it seems the app crashes when the NFC presentment intent is shown and 60 seconds passed and user does nothing. The app just crashes after 60 seconds. On previous iOS versions, I know that CardSession.Error.maxSessionDurationReached was thrown after 60 seconds. Is something changed in iOS 26?

Pushkit/Callkit with unlocked SIM before first unlock
We have a problem in a scenario that SIM lock is disabled so after a phone reboots it has the Internet connection but it is still locked. When you call into the VOIP app the app is not being launched as the result (it seems reasonable because it wouldn't be able to access the keychain items etc...) but the OS still seem to enforce the rule that the app needs to report the new incoming call. When we then unlock the app we can see no more pushkit pushes are arriving (dropped on the floor in the console) but we get the three initial pushes that were send during the locked phase right after the app launch.

Is MetricKit automatically on all devices?
Hello Apple, I am trying to get information such as crash context whenever a user encounters a situation where the app is killed. I was wondering if the tool MetricKit is available to all users or is this a feature to those who has opted into it. I am aware that the whenever someone gets a new device or in settings, an option will appear that'll have users decide whether or not to have Apple receive data analytics during certain events on their device. Does this have any effect on whether some users may not have MetricKit? Overall, we are attempting to use MetricKit to better analyze performance of our app. It would be inefficient for us, if the population of users using MetricKit is only those who have opted into it. Thanks, dmaliro

Issue with RCS Message Filtering on iOS 18.2.1 and 18.3
Hi Apple Developers, I am currently working on a message filtering application and facing issues specifically with filtering RCS (Rich Communication Services) messages. To debug this, I created a sample app that consistently categorizes all incoming messages as "junk." However, the filtering behaviour is inconsistent and not functioning as expected. Here are the key issues observed during testing on iOS versions 18.2.1 and 18.3: Inconsistent Filtering Behavior: When a message is received from an unknown number, it sometimes gets moved to the Junk folder momentarily but is then immediately moved back to the main Messages inbox. In some cases, the message does not get moved to the Junk folder at all, despite the app returning the verdict as "junk." Duplicate Contact Tiles: The Messages app displays two separate conversation tiles for the same mobile number, which is unexpected behavior. I have attached both a sample app and a screen recording that clearly demonstrates the issue. The recording shows that the app categorizes messages as junk, yet they still end up in the main Messages inbox. For reference, my carrier partner is T-Mobile. Please let me know if you need any additional information to investigate this issue further. Looking forward to your insights and guidance. Best regards, Rijul Singhal

[iOS 26] [CallKit] [SDK 26] Application got crashed while App was Inactive
The crash log, an IPS file, indicates a crash occurred at a specific time, with the exception backtrace pointing to _terminateAppIfThereAreUnhandledVoIPPushes. However, cross-reference with the SysDiagnose logs, there is no corresponding process or activity for the application at the reported crash time. The app was not active, nor was it woken up by any event. IPS file and SysDiagnose logs have been attached in the Feedback. Feedback - FB20044587
