Message Filter Extension won't use Basic Auth
I am trying to set up a message filter extension that will use shared web credentials for basic auth when calling to its ILMessageFilterExtensionNetworkURL. I have associated domains set up for both "messagefilter:" and "webcredentials:" and the message filter IS correctly calling the ILMessageFilterExtensionNetworkURL with each message - so that part is working. As detailed here, I have set up Shared Web Credentials and my view controller is using SecAddSharedWebCredential() to save the creds to the correct domain. Using Authorization services, the creds are auto-filled into my app's login screen. When I go under Settings > Passwords, I see the creds are saved and they are the correct creds to the corrent website that matches ILMessageFilterExtensionNetworkURL. Regardless of all of this, the deferQueryRequestToNetwork() refuses to use the creds and implement Basic Auth in its URL call. It makes the call to the correct URL, it just won't use the Shared Web Creds for basic auth. Any help would be greatly appreciated.

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

macOS 15.1 MFMailComposeViewController.canSendMail() returns false always
In my Catalyst app I use func setupMailComposer() { // Check if the device can send email guard MFMailComposeViewController.canSendMail() else { print("Mail services are not available") showMailErrorAlert() return } // Create and configure the mail composer let mailComposeVC = MFMailComposeViewController() mailComposeVC.mailComposeDelegate = self // Set the email details mailComposeVC.setToRecipients(["example@example.com"]) mailComposeVC.setSubject("Subject for your email") mailComposeVC.setMessageBody("This is the body of the email.", isHTML: false) // Attach a file (optional) if let filePath = Bundle.main.path(forResource: "example", ofType: "pdf"), let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) { mailComposeVC.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "example.pdf") } // Present the mail composer self.present(mailComposeVC, animated: true, completion: nil) } Since I have updated to macOS 15.1 the canSendMail() function returns false although I have configured Apple Mail (like before in 15.0 where it worked flawlessly).

Add 'PDF Services' symlink in ~/Library directory in SwiftUI macOS Catalyst application
I am trying to port my sandboxed macOS app completely over to iOS using a Catalyst target. In my macOS app, I use 'SwiftySandboxFileAccess' package to add a symlink to '~/Library/PDF Services' so that the 'share to my app' menuItem shows up in the macOS Print Panel (in the PDF menu). It is critical for the function of my app to have this work on macOS. In the Catalyst target, I am having problems gaining access to '~/Library'. I have tried having the user select the folder, but the picker always returns 'canceled'. I have a test app that illustrates this. The test app tries to coax the user into selecting the library folder and then it is supposed to bookmark the location, but I am unable to get this far. As an aside, macOS should probably automatically add an entry to the Print Panel when the app includes PDF as a document type in XCode; it would save a lot of hassle and avoid having to go outside of the sandbox. However, I cannot wait for that. Hopefully someone can help. Download Test App from iCloud (If you have problems downloading the file, it might be because of some iCloud share setting that I am not aware of. Just tell me and I'll figure something out.)

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

Alarms scheduled using AlarmKit is not reliable
The alarms that I am scheduling using alarmKit is not reliable at all, especially in beta 8 (Used to have this issue in previous betas, But they were inconsistent). The alarm fires anywhere after 5 mins to 45 mins from the actual scheduled time. I'll share the relevant code block here in case if it is me who is doing something wrong. This code block doesn't throw any errors and I am also able to see the scheduled alarms when I query them. The issue is with alarms not firing on the specified time let alert = AlarmPresentation.Alert( title: "Wakey Wakey!", stopButton: .init(text: "stop", textColor: .red, systemImageName: "stop.fill") ) let presentation = AlarmPresentation(alert: alert) let attributes = AlarmAttributes<CountDownAttribute>( presentation: presentation, metadata: .init(), tintColor: .orange ) let schedule = Alarm.Schedule.fixed(alarmTime) let config = AlarmManager.AlarmConfiguration( schedule: schedule, attributes: attributes ) let id = UUID() do { let alarm = try await AlarmManager.shared.schedule(id: id, configuration: config) print("Alarm set successfully for \(alarmTime) - \(alarm)") } catch { print("Failed to schedule alarm: \(error)") }

FRONTBOARD crash App killed while running in the background.
PLATFORM AND VERSION iOS Development environment: Xcode 16.2, macOS 15.5 Run-time configuration: iOS 18 DESCRIPTION OF PROBLEM Our app (a VoIP and messaging app) has been experiencing a crash when running in the background for long periods of time (a couple of days) while receiving calls, and message notifications. If the app is not receiving notifications, we don't get any crashes while it runs in the background. It is worth mentioning that we have several pushes that are background pushes and they could happen depending on the outcome of an incoming call. We have the two pushes: incoming call bye: let the app know that the calling end hanged up the call. incoming call answered: lets the app know that another device (with the same shared number) answered the call (web app, Android). Those pushes are delivered within 30 seconds after the call starts. I assume that since the app was awakened by a VoIP push, those background notification won't count towards the iOS restriction of not getting too many background pushes: "The number of background notifications allowed by the system depends on current conditions, but don’t try to send more than two or three per hour." Let me know if the above assumption is not accurate. I don't see details in the crash report (such as a "Termination Description") that could guide me to address the issue. So I would appreciate if you can give me some insight on what could be causing this. Here is part of the crash report: Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: FRONTBOARD 0xbaadca11 <RBSTerminateContext| domain:10 code:0xBAADCA11 explanation: reportType:CrashLog maxTerminationResistance:Interactive> Triggered by Thread: 0 Thread 0 name: Thread 0 Crashed: 0 libsystem_kernel.dylib 0x00000001dda93ce4 mach_msg2_trap + 8 1 libsystem_kernel.dylib 0x00000001dda9739c mach_msg2_internal + 76 (mach_msg.c:201) 2 libsystem_kernel.dylib 0x00000001dda972b8 mach_msg_overwrite + 428 (mach_msg.c:0) 3 libsystem_kernel.dylib 0x00000001dda97100 mach_msg + 24 (mach_msg.c:323) 4 CoreFoundation 0x000000018c886900 __CFRunLoopServiceMachPort + 160 (CFRunLoop.c:2637) 5 CoreFoundation 0x000000018c8851f0 __CFRunLoopRun + 1208 (CFRunLoop.c:3021) 6 CoreFoundation 0x000000018c886c3c CFRunLoopRunSpecific + 572 (CFRunLoop.c:3434) 7 GraphicsServices 0x00000001d9a65454 GSEventRunModal + 168 (GSEvent.c:2196) 8 UIKitCore 0x000000018f299274 -[UIApplication run] + 816 (UIApplication.m:3845) 9 UIKitCore 0x000000018f264a28 UIApplicationMain + 336 (UIApplication.m:5540) 10 SwiftUI 0x00000001913a97a4 closure #1 in KitRendererCommon(:) + 168 (UIKitApp.swift:68) 11 SwiftUI 0x00000001910af01c runApp(_:) + 112 (UIKitApp.swift:16) 12 SwiftUI 0x00000001910aeed0 static App.main() + 180 (App.swift:136) 13 TheApp Business 0x0000000100686028 static TheApp_BusinessApp.$main() + 52 (TheApp_Business.swift:0) 14 TheApp Business 0x0000000100686028 main + 64 15 dyld 0x00000001b375bf08 start + 6040 (dyldMain.cpp:1450) STEPS TO REPRODUCE Open the app. Leave the app running in the background while it is receiving notifications (VoIP or messages).

Problem NumberFormatter with Locale
We have identified an issue when using NumberFormatter with the locale set to it_IT. Specifically, when formatting numbers with exactly four integer digits, the grouping separator is not applied: for example, the number is displayed as 4000,00 instead of the expected 4.000,00. This behavior occurs only with four-digit integers; for instance, 40.000,00 is formatted correctly. The issue appears to affect only iOS 18.4 and later versions.

App Crashing iOS26
I have four apps currently deployed on the App Store. One of these apps crashes on launch when running on iOS 26, but functions as expected on iOS 18 and earlier versions. I am seeking to understand what changes in iOS 26 might be causing this issue. When running the app in debug mode on devices with iOS 26 using Xcode 16.1, the app crashes. The crash log references libobjc-trampolines.dylib, suggesting a potential issue with the Objective-C runtime. Has anyone else encountered a similar issue? AGX: AGX: agxa_device_template.hpp:1467:setupCompiler: *** FATAL: driver shader binary file not found in (null) for extension g15p!!! D [yHZ]: added warning: [MEDIUM]: SW04: A debugger is attached to the App. D [ProbeCallbacks]: [IXGUARD] debugger detected objc[1461]: couldn't dlopen libobjc-trampolines.dylib: dlopen(/usr/lib/libobjc-trampolines.dylib, 0x0106): tried: '/usr/lib/system/introspection/libobjc-trampolines.dylib' (no such file, not in dyld cache), '/usr/lib/libobjc-trampolines.dylib' (no such file), '/private/preboot/Cryptexes/OS/usr/lib/libobjc-trampolines.dylib' (open() failed with errno=24), '/usr/lib/libobjc-trampolines.dylib' (no such file, not in dyld cache) What steps can I take to resolve this crash? Thank you for your assistance.

Device Activity Report Not showing any information
All After about 20 hours straight of working on this and having scrapped it twice I am realizing I should have asked everyone here for help. I am just trying to get device activity report extension to work inside an existing app. I have been heavily using family controls, managedsettings and deviceactivity and decided it would be nice to output some of the app usage so the User (parent) can see their children's app usage. I installed the target via xcode, confirmed group names match, and think I have it embedded correctly but when I run the app and call the view within the extension to show minutes used by any apps it just shows no time has been used. In addition, when I put print statements into the extension they do not show up in console. I have confirmed the main app target-&gt;Build phases-&gt;Link binary with Libraries has: ManagedSettings.framework FamilyControls.Framework DeviceActivity.framework I have confirmed in xcode that the main app target-&gt;Build phases -&gt; Embed Foundation Extensions has: ShieldConfiguration.appex ShieldActionExtension.appex DeviceActivityMonitor.appex I have confirmed in xcode that the main app target-&gt;Build phases-&gt; Embed ExtensionKit Extensions has: UsageReportExtension.appex I have used the apps I am trying to show data for extensively in the last 36 hours. Here is my UsageReportExtension info.plist EXAppExtensionAttributes EXExtensionPointIdentifier com.apple.deviceactivityui.report-extension .entitlement com.apple.developer.family-controls com.apple.security.application-groups group.com.jrp.EarnYourTurnMVP2.data Here is the file in the app (timebankview.swift) calling the extension/showing the extension view(AppUsageReportView.swift) import DeviceActivity import ManagedSettings struct TimeBankView: View { @EnvironmentObject private var appState: AppState @State private var reportInterval: DateInterval = { let calendar = Calendar.current let now = Date() let yesterdayDate = calendar.date(byAdding: .day, value: -1, to: now) ?? now return DateInterval(start: yesterdayDate, end: now) }() private var reportFilter: DeviceActivityFilter { let selection = appState.screenTimeController.currentSelection return DeviceActivityFilter( segment: .daily(during: reportInterval), users: .children, devices: .all, applications: selection.applicationTokens, categories: selection.categoryTokens // webDomains: selection.webDomains // Add if needed ) } var body: some View { ZStack { Color.appTheme.background(for: appState.isParentMode) .edgesIgnoringSafeArea(.all) ScrollView { VStack(spacing: 20) { Text("Time Bank") DeviceActivityReport(.childUsageSummary, filter: reportFilter) Here is AppUsageReportView.swift import SwiftUI struct AppUsageReportView: View { let config: DetailedAppUsageConfiguration // Use the detailed config var body: some View { VStack { Text("App Usage Details") Text("Total Screen Time: \(config.totalDurationFormatted)") if config.applicationsUsed.isEmpty { Text("No specific app usage data available for the selected period/filter.") } else { Text("Apps Used:") List { ForEach(config.applicationsUsed) { appInfo in HStack { Image(systemName: "app.dashed") Text(appInfo.appName) .lineLimit(1) Text(appInfo.durationFormatted) Here is AppUsageReportScene.swift: import SwiftUI import ManagedSettings struct AppInfo: Identifiable, Hashable { let id = UUID() let appName: String let durationFormatted: String } struct DetailedAppUsageConfiguration { var totalDurationFormatted: String = "Calculating..." var applicationsUsed: [AppInfo] = [] } struct AppUsageReportScene: DeviceActivityReportScene { let context: DeviceActivityReport.Context = .childUsageSummary let content: (DetailedAppUsageConfiguration) -&gt; AppUsageReportView func makeConfiguration(representing data: DeviceActivityResults&lt;DeviceActivityData&gt;) async -&gt; DetailedAppUsageConfiguration { var config = DetailedAppUsageConfiguration() var appDurations: [String: TimeInterval] = [:] var totalAggregatedDuration: TimeInterval = 0 let formatter = DateComponentsFormatter() formatter.allowedUnits = [.hour, .minute, .second] formatter.unitsStyle = .abbreviated formatter.zeroFormattingBehavior = .pad var segmentCount = 0 var categoryCount = 0 var appCount = 0 for await activityData in data { // Check segments var tempSegmentCount = 0 for await segment in activityData.activitySegments { segmentCount += 1 tempSegmentCount += 1 totalAggregatedDuration += segment.totalActivityDuration var tempCategoryCount = 0 for await categoryActivity in segment.categories { categoryCount += 1 tempCategoryCount += 1 var tempAppCount = 0 for await appActivity in categoryActivity.applications { appCount += 1 tempAppCount += 1 let appName = appActivity.application.localizedDisplayName ??

Need to check Call Status without using CallKit
My app requirement is to check that User is on call while doing transaction. If user on call then we need to show Caution alert. For this requirement we used CallKit to detect Call status and it's working fine but recently Apple has rejected the application because of Callkit that is banned in China. Could you please provide any solution to check the Call Status only.

Permission error occurs when I use setDefaultApplication(at:toOpen:completion:)
I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 "permErr: permissions error (on file open)"}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

BadDeviceToken Error in Live Activities
Hello everyone, I’m currently receiving feedback from clients in a production environment who are encountering a BadDeviceToken error with Live Activities, which is preventing their states from updating. However, for other clients, the token is working fine and everything functions as expected. I’m collaborating with the back-end developers to gather more information about this issue, but the only log message we’re seeing is: Failed to send a push, APNS reported an error: BadDeviceToken I would greatly appreciate it if anyone could provide some insight or information on how to resolve this issue.

DeviceActivity Report Extension cannot pass App Store Connect validation without becoming un-installable on device
I'm running into a contradictory requirement involving the DeviceActivity Report extension (com.apple.deviceactivityui.report-extension) that makes it impossible to both: upload the app to App Store Connect, and install the app on a physical device. This creates a complete catch-22. 📌 Overview My extension: Path: Runner.app/PlugIns/LoADeviceActivityReport.appex Extension point: com.apple.deviceactivityui.report-extension Implementation (SwiftUI): import SwiftUI import DeviceActivity @main struct LoADeviceActivityReport: DeviceActivityReportExtension { var body: some DeviceActivityReportScene { // ... } } This is the standard SwiftUI @main DeviceActivityReportExtension template. 🟥 Side A — iOS runtime behavior (device installer) If I add either of these keys to the extension's Info.plist: NSExtensionPrincipalClass NSExtensionMainStoryboard then the app cannot be installed on a real iPhone/iPad. The device installer fails with: Error 3002 AppexBundleContainsClassOrStoryboard NSExtensionPrincipalClass and NSExtensionMainStoryboard are not allowed for extension point com.apple.deviceactivityui.report-extension. To make the app install and run, I must remove both keys completely. This leaves the extension Info.plist like: NSExtension NSExtensionPointIdentifier com.apple.deviceactivityui.report-extension With this, the app installs and runs correctly. 🟥 Side B — App Store Connect upload validator However, when I upload the IPA with the runtime-correct Info.plist, App Store Connect rejects it: State: STATE_ERROR.VALIDATION_ERROR (HTTP 409) Missing Info.plist values. No values for NSExtensionMainStoryboard or NSExtensionPrincipalClass found in extension Info.plist for Runner.app/PlugIns/LoADeviceActivityReport.appex. So ASC requires that at least one of those keys be present. 💥 The catch-22 If I add PrincipalClass / MainStoryboard: ✔ App Store Connect validation passes ❌ But the app can NOT be installed on any device (Error 3002) If I remove PrincipalClass / MainStoryboard: ✔ The app installs and runs correctly ❌ ASC rejects the upload with “Missing Info.plist values” There is currently NO Info.plist configuration that satisfies both: Runtime: "NSExtensionPrincipalClass and NSExtensionMainStoryboard are not allowed." App Store Connect: "You must include NSExtensionPrincipalClass or NSExtensionMainStoryboard." 📌 Expected behavior For SwiftUI @main DeviceActivityReportExtension, the documentation and examples suggest the correct configuration is: NSExtensionPointIdentifier com.apple.deviceactivityui.report-extension with no principal class or storyboard at all. If that is correct for runtime, ASC seems to need updated validation rules for this extension type. ❓My Questions What is the officially correct Info.plist configuration for a SwiftUI DeviceActivityReportExtension? Should principal class / storyboard not be required for this extension type? Is this a known issue with App Store Connect validation? Is there currently a workaround that allows: installation on device and successful App Store Connect upload, without violating runtime restrictions?

KVO crashes in older OS-Versions not replicable in Sequoia
Greetings, With MacOS 15 Sequoia, Apple updated key-value-observations in such a way, that an unremoved observation by a now deallocated object will no longer cause an exception, when the observed object triggers said observation. While this is fundamentally a positive change, the issue comes with the fact, that this change affects systems based on the version of their operating system and not the version of the operating system of the build system. Many of our customers use old operating system versions and old hardware - meaning they can't easily update. Since we need to use up to date Xcode versions to develop for newer systems, our developers tend to have rather new OS versions. This means, that we are increasingly facing bugs which only happen in customer systems but not in most developer (or QA) systems. Currently, we still can use earlier OS versions with Xcode to fix these bugs, but once the used Xcode versions no longer support MacOS 14 or below this will become a major hurdle. Are there known solutions to this issue? We are currently attempting to swizzle observer adding and removal in order to fix the problem for old systems as well, but this has proven to be quite difficult and unstable. Since any weakly held property in the middle of an observation keypath can cause crashes, one would have to split up observations into multiple subobservations, which is less simple than it sounds, due to custom implementations of addObserver (such as there seems to be in array controller proxies) and collection operators. Thanks for any suggestions!
