After porting my app to Swift 6 local notifications produce a sound, but no alert
My app produces local notification but unfortunately they only play a sound but do not produce an alert. Of course I requested authorization with: let center = UNUserNotificationCenter.current() center.requestAuthorization(options: [.alert, .sound]) {(granted, error) in // Enable or disable features based on authorization. } And scheduled the notification with: func localNotification(_ title:String, message:String, sound:UNNotificationSound?, badge:Int?, interval:TimeInterval, userInfo: [AnyHashable : Any]?, category:UNNotificationCategory?=nil){ let content = UNMutableNotificationContent() content.title = NSString.localizedUserNotificationString(forKey: title, arguments: nil) content.body = NSString.localizedUserNotificationString(forKey: message, arguments: nil) content.sound=sound let ti = NSInteger(interval) let seconds = ti % 60 let minutes = (ti / 60) % 60 let hours = (ti / 3600) //let ms = Int((interval.truncatingRemainder(dividingBy: 1)) * 1000) var dateInfo = DateComponents() dateInfo.hour=hours dateInfo.minute=minutes dateInfo.second=seconds let trigger = UNCalendarNotificationTrigger(dateMatching: dateInfo, repeats: false) let request = UNNotificationRequest(identifier: "EndOfMeditation", content: content, trigger: trigger) let center = UNUserNotificationCenter.current() center.delegate = self center.add(request) { (error : Error?) in if let theError = error { print(theError.localizedDescription) } } } and have no queue about to know better.

Silent Push background launch rejected with "pushDisallowed" and "AMNP" on TestFlight build
Hello, I am implementing background processing using Silent Push Notifications in an iOS application. The app needs to receive requests from a server and execute processing in the background. For this purpose, I am using Silent Push Notifications to wake up the application. However, the application is not being launched as expected when running the TestFlight version. I would appreciate any guidance regarding this behavior. Environment Xcode 26.3 iOS 18.6 TestFlight distribution Push Notifications capability enabled Background Modes enabled Remote notifications enabled APNs Authentication Key (.p8) APNs Production environment Background Previously, the application periodically connected to a server in the background and sent location information when requested by the server. Since that background processing no longer behaves as expected, I started implementing an alternative approach using Silent Push Notifications. When running the application directly from Xcode in Debug mode, Silent Push works correctly and the app is launched in the background. However, when using the TestFlight build on the same device, the behavior differs and the app is not launched in the background. Observed Behavior The APNs request appears to be successful: APNs response status is HTTP 200 Using the device token obtained from the TestFlight build Alert Push notifications are received successfully application:didReceiveRemoteNotification:fetchCompletionHandler: is called when the app is in the foreground The same method is not called when the app is in the background Silent Push payload: { "aps": { "content-available": 1 } } HTTP/2 headers: apns-push-type: background apns-priority: 5 Verified Items Production device token is being used APNs topic matches the application's bundle identifier Alert Push notifications work correctly Background App Refresh is enabled on the device The application has not been force-quit completionHandler is always called after processing completes Console Logs The following logs appear when the push is sent: Submitted: com.apple.pushLaunch.jp.co.comp.MyApp.ext.mdm Application Policy response: {100, 0.00, [{[pushDisallowed]: Required:0.00, Observed:1.00},]} Decision: AMNP I also see: Insufficient history window for deviceActivityLikelihood stream deviceActivityLikelihood returned a nil timeline Questions Under what conditions are pushDisallowed and Decision: AMNP generated? What factors can cause iOS to reject a background launch triggered by a Silent Push Notification? Since Alert Push notifications are received successfully, is it reasonable to conclude that APNs configuration, topic configuration, and device token usage are correct? Are there any specific settings, entitlements, or implementation details that should be reviewed to resolve the pushDisallowed condition? The behavior differs between the Debug build launched from Xcode and the TestFlight build running on the same device. Are there any restrictions, policies, or differences applied to TestFlight builds that could explain this behavior? If the observed behavior is expected by design, what would Apple recommend as the appropriate architecture or API for server-triggered background processing in this scenario? Thank you for your time and assistance.

APNs push never delivered — even a direct FCM test message fails
Push notifications are never delivered to my iOS app and I've exhausted the usual checks. Bundle: com.thomasmanfredini.lafrench, Team 7TWV3839F3, TestFlight (production). Architecture: Firebase Cloud Messaging (the app registers an FCM token; Firebase relays to APNs). Key symptom: a direct FCM test message (Firebase Console → "Send test message") to a valid registration token delivers nothing (app killed, lock screen). Already verified (all correct): notification permission ON (incl. Lock Screen); TestFlight build with aps-environment=production; GoogleService-Info.plist matches the Firebase iOS app (project la-french, sender 649219813428); FCM token generated and valid; APNs Auth Key in Firebase with correct Key ID + Team ID — tried two keys (one Production, one Sandbox & Production), neither delivers; bundle ID matches the APNs topic. Since even a direct FCM test fails with a valid token and correct config, what could prevent APNs from delivering to this app? What should I check next (account-level APNs, Push Notifications capability on the App ID, etc.)? Thanks!

Unexpected Third-Party Notifications During Edu-Assessment mode (Single app mode)
Hello, We have an assessment application that placing the device into Education Assessment Mode (also referred to as Single App Mode) to provide a secure exam environment. On our test devices, Education Assessment Mode behaves as expected. While an assessment session is active, we have verified that third-party notifications (such as WhatsApp and Snapchat) do not appear. However, one of our customers recently reported that during an active exam, a Snapchat notification was displayed while the device was still in Education Assessment Mode. We have been unable to reproduce this behavior on any of our test devices, even after repeated testing with the same application. Has anyone experienced similar behavior with education assessment mode? Specifically: Can there be any scenario where third-party notification banners are shown while an assessment session is active? Are there any known edge cases or system conditions that could allow notifications to appear during Education Assessment Mode? Is there any way to verify from the application that the assessment session is still fully enforced by the system? We're also interested in knowing whether Apple is aware of any issues related to notification suppression while an education assessment mode is active. Any insights would be greatly appreciated. Thank you.

Is V2 → V1 rollback via Modify App API fully supported in production?
We’re planning a migration from App Store Server Notifications V1 to V2 and are reviewing our rollback strategy before enabling V2 in production. While researching, we found TN3180: TN3180: Reverting to App Store Server Notifications V1 | Apple Developer Documentation The technote appears to describe reverting App Store Server Notifications from V2 back to V1 using the Modify an App endpoint. Before proceeding, we’d like to clarify a few points: Is V2 → V1 rollback via the Modify App endpoint fully supported for production applications? If an application is reverted from V2 back to V1, can it later be migrated back to V2 again? During a rollback, should developers expect any overlap period where both V1 and V2 notifications may be delivered due to retries or notifications already in flight? Our goal is to understand whether the V2 → V1 capability should be treated as a fully supported operational rollback mechanism or as an emergency recovery path intended only for exceptional situations. Thank you for any clarification.

Documentation on APNS Live Activity Broadcast API throttle limit
Hi Team We are building a live activity feature for our app. While using the APNS broadcast API (https://api.push.apple.com:443/4/broadcasts/apps/), we are getting throttled. The updates are infrequent (sport games) and yet we are facing this issue. Our understanding was that the throughput is quite high but there is no documentation on the actual limitations. Furthermore, all of our updates are using a priority of 5. We have currently configured retry with exponential backoff and jitter but we would like to understand the APNS throttle limit for live activity broadcast. Is the limit per channel id or at API level? What is the hard limit for the API request per seconds? Can we request increase to the API rate limit?

Future roadmap for APNs token authentication: Granular app-scoped keys and ephemeral tokens?
"The introduction of team-scoped keys is a fantastic step forward for tightening security and isolating responsibilities within larger development organizations. However, as infrastructure moves closer to Zero Trust architectures, managing these keys across decentralized microservices or CI/CD pipelines still presents challenges. I have two questions regarding the long-term roadmap for APNs authentication: 1 App-Level Scoping: Are there plans to allow authentication keys to be scoped down to specific App IDs (Bundle IDs) rather than the entire team? Currently, a compromised team-scoped key could still potentially impact other apps within the same developer account. 2 Short-lived / Ephemeral Tokens: Is Apple considering support for short-lived, dynamically generated authentication tokens (similar to AWS IAM roles or OAuth 2.0 client credentials with expiration) to eliminate the need for storing long-lived ⁠.p8⁠ master keys on third-party backend servers? Understanding the direction of APNs security would greatly help us architect our next-generation notification backend."

Recommendation for leveling up notification game
Years ago a notification evangelist had recommended supporting NotificationContentExtension and NotificationServiceExtension. Fast forward to notification AI summaries, live activities, and lock screen widgets, iPhone mirroring, and all the others I'm missing, are there any other features developers should be utilizing when building out a notification strategy? Conversely, are there things to look out for if we DON'T adopt something as a negative? For context, the notifications might be general all audience, as well as, direct to user with custom content.

Updating Notifications
When updating Notifications, is it best practice to delete and reset all of them, or just delete and reset the Notifications that need to change? We have data coming from multiple sources, and as a result, we are often updating the notifications. This can be several times in under 10 seconds.

Recommended approach for persistent emergency alarms on iOS
We have an emergency alert app that can trigger alarms in the event of a potential accident. We currently use Critical Alerts, which works well when the app is suspended or running in the background. A key requirement is that the alarm continues playing until the user explicitly acknowledges or dismisses it, as nearby people may need to notice the alarm and assist. Today, we’re achieving this by scheduling multiple Critical Alert notifications with the maximum sound duration (30 seconds) to create a longer continuous alarm. While this mostly works, it feels like a workaround and isn’t fully reliable. Is there a recommended way to implement a persistent emergency alarm experience on iOS? Would AlarmKit be an appropriate solution for this use case, or is it intended only for user-scheduled alarms and timers? Are there any other APIs or patterns you would recommend?

AlarmKit — disabling haptics when alarm fires?
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!

AlarmKit dense fan-out scheduling: alarms intermittently fire late or not at all on locked iOS 26.x device
Hi all, I'm building an iOS alarm app on AlarmKit (iOS 26+) and running into reliability issues I can't find documented anywhere. Hoping someone here has insight. What we're doing We schedule a "fan-out" pattern, a single user-set alarm becomes a sequence of AlarmKit alarms firing at regular intervals over ~50 minutes. The density is needed because we require repeated wake-up alerts the user can't easily ignore until they complete an explicit dismissal action. A single AlarmKit alarm that auto-mutes after Apple's default duration doesn't solve the heavy-sleeper case. We've seen other iOS alarm apps use a similar approach reliably on iOS 26+, so the pattern seems achievable. We're clearly missing something about AlarmKit's behavior under dense scheduling. The issue AlarmKit alarms intermittently fail to enter .alerting at their scheduled times when the device is locked. Lateness varies from ~20 seconds up to 4+ minutes. The bug is intermittent ie. no deterministic reproducer. When the lateness is short (~15-22s), the next alarm in the sequence often fires only a few seconds later, suggesting the first two get bunched rather than firing independently. When the lateness is long (minutes), our AlarmManager.shared.alarmUpdates subscriber observes zero .alerting transitions during the gap, then receives a flurry of events when the device wakes. Verified via on-thread Swift logging, not a bridge or JS-suspension issue. Our setup AlarmManager.AlarmConfiguration with .fixed(date) schedule, AlarmAttributes + stop button, StopAlarmIntent, custom .named(...) sound No alerting duration specified (we don't believe one is exposed) NSAlarmKitUsageDescription set; AlarmKit authorized Registered WidgetExtension for the auto Live Activity No Critical Alerts entitlement (docs suggest AlarmKit doesn't need it) Questions Is there a documented or undocumented density limit for AlarmKit alarms scheduled in close succession? What is iOS's behavior when multiple AlarmKit alarms are simultaneously in .alerting state? Coalesce? Queue? Drop? Is there a supported way for the app to control per-alarm alerting duration before iOS auto-mutes? For locked-overnight scenarios, are there documented power-management or dasd interactions that defer AlarmKit fires? Does declaring UIBackgroundModes fetch/processing affect this? Any insight or a point in the right direction would be super appreciated!

Push Notification Icon Not Updated on Some Devices After App Icon Change
Hi, We recently updated our app icon, but the push notification icon has not been updated on some devices. It still shows the old icon on: • iPhone 16 Pro — iOS 26 • iPhone 14 — iOS 26 • iPad Pro 11” (M4) — iOS 18.6.2 • iPhone 16 Plus — iOS 18.5 After restarting these devices, the push notification icon is refreshed and displays the new version correctly. Could you advise how we can ensure the push notification icon updates properly on all affected devices without requiring users to restart? Thank you.

Tips to test/debug silent pushes in Test Flight when throttled
Populating widgets with silent push notifications would be great for us if they were more predictable. Can you share tips for debugging / testing in Test Flight beyond the usual recommendations available online? When messages are not processed it is a major challenge to distinguish between code problems and device throttling.

Hi, We recently updated our app icon, but the push notification icon has not been updated on some devices. It still shows the old icon on: • iPhone 16 Pro — iOS 26 • iPhone 14 — iOS 26 • iPad Pro 11” (M4) — iOS 18.6.2 • iPhone 16 Plus — iOS 18.5 After restarting these devices, the push notification icon is refreshed and displays the new version correctly. Could you advise how we can ensure the push notification icon updates properly on all affected devices without requiring users to restart? Thank you.
