I understand that with the 26.4.2 patch, when you click on a notification preview to check a text message, the saved preview data is deleted. So, what should I do to delete the preview data that was left over from clicking on notification previews before the 26.4.2 patch? First of all, I don't want to do a factory reset. So I'm just want to know about this.

For many months now we've been building a watchOS app with push support. On device, these usually work fine, but in the sim, only loud pushes are ever received (don't contain content-available). This includes pushes triggered from our backend, whether directly or through Firebase Cloud Messaging, from Apple push web interface, from apns files dropped onto the sim, or from files sent using simctl push. All say they were sent successfully, none trigger any of the push related WKApplicationDelegate methods. As I understand it, only didReceiveRemoteNotification should be triggered for this kind of push. Additionally, can anyone confirm what the proper background mode setup is for push notifications on watchOS? Is it supposed to remote-notification under UIBackgroundModes or WKBackgroundModes? For WKBackgroundModes Xcode only offers a few watch specific values, but not the push value. The docs are unclear on this part.

I'm seeing a timestamp display issue on Apple Watch Notification Center, and I'd like to confirm whether this is a known watchOS behavior or whether there's a setup mistake on our side. Symptom The same APNs notification displays the correct time on iPhone Notification Center and on the initial Apple Watch banner. After the Watch screen turns off and the user later opens Notification Center on Apple Watch, the same notification may show an incorrect relative timestamp such as "3 hours ago" or even "yesterday". The drift is per-notification and persists for that notification until it's dismissed. iPhone NC always shows the correct time. WhatsApp tested side-by-side on the same iPhone/Watch pair does not show this drift. Setup iOS 26.4.2 on iPhone 16 Pro watchOS 26.4 on Apple Watch Series 10 App with paired Apple Watch A UNNotificationServiceExtension that decrypts E2EE message previews and applies Communication Notification enrichment via INSendMessageIntent and content.updating(from:) Production APNs environment, TestFlight builds No beta software Isolation tests already performed Test mutable-content NSE invoked Drift on Watch NC Minimal APNs (alert + sound only) no no no drift NSE skips content.updating(from:), INInteraction.donate/delete (still calls them as no-op via diagnostic build) yes yes — modifies content drift NSE bypasses ALL Intents/Communication Notification APIs (no INPerson, no INSendMessageIntent, no avatar, no updating(from:)); just modifies title/body/sound/category and returns the mutable copy yes yes — modifies content drift Production-like APNs payload (thread-id, target-content-id, category, sound, badge, custom userInfo) but WITHOUT mutable-content no no no drift Eliminated as causes: content.updating(from:), INSendMessageIntent, INInteraction.donate, INInteraction.delete(with:), INPerson/INPersonHandle (not even constructed in test 3), avatar fetching, thread-id, target-content-id, category, sound, badge, custom userInfo, custom createdAt timestamp, stale Siri/Apple Intelligence history (cleared manually on iPhone and Watch). The pattern The only consistent variable distinguishing the no-drift cases from the drift cases is whether mutable-content: 1 is set on the APNs payload (i.e. whether the UNNotificationServiceExtension is invoked). Once invoked, the extension's behavior with respect to Communication Notifications does not seem to affect the outcome — the drift reproduces even when the NSE only modifies title/body/sound and returns. Questions Is there a known watchOS behavior where notifications processed by a UNNotificationServiceExtension use a different timestamp source on Apple Watch Notification Center after the Watch screen has been turned off and reopened, while the initial Watch banner and iPhone Notification Center show the correct delivery time? Are there specific UNMutableNotificationContent properties or APNs payload flags that should be preserved (or avoided) when returning content from an NSE to keep the Watch NC timestamp consistent with the delivery time? For E2EE messaging apps, is there a recommended pattern to decrypt and return content from an NSE that avoids this drift on watchOS? Happy to provide an anonymized snippet of NotificationService.swift and the APNs payload format if useful. Thanks.

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!

We have an app that uses PushKit and CallKit for video calling. These are often emergency calls, so very latency-sensitive. We keep track of when we sent out the APNs request and when the phone started ringing. The p95 latency is about 2 seconds (mean is ~800ms), which feels quite long.. Is this normal? I'd expect <500ms most of the time given that the devices and servers are all within the US. The users typically have a stable internet connection. Our requests look like this: POST https://api.push.apple.com/3/device/<DEVICE_TOKEN> apns-topic: com.vpt.physician.voip apns-push-type: voip apns-priority: 10 apns-expiration: 0 authorization: bearer <APNS_PROVIDER_TOKEN> content-type: application/json {  "aps": {    "content-available": 1  },  "title": "Example Text",  "type": "CallFromTablet",  "timeout_ms": 30000 } If there's any more info I can provide to help troubleshoot this, let me know. Thanks in advance.

Hello, We are planning to shut down our mobile app service and need to discontinue our auto-renewable subscription product. Our service termination date is July 31, and we are currently preparing the backend implementation for this. We have reviewed the official documentation and Apple Developer Forums, but there are several behaviors we cannot confirm through sandbox testing, as the "Remove from Sale" setting does not appear to affect the sandbox environment. We would greatly appreciate clarification on the following: Server notification at the moment of "Cleared for Sale" being unchecked When we uncheck "Cleared for Sale" in App Store Connect, is any App Store Server Notification (V2) sent to our server immediately at that moment? If yes, what is the exact notificationType and subtype value sent? If no, when is the first notification triggered for existing active subscribers after this action? 2. Notification sequence from product removal through final expiration For existing active subscribers, what is the exact sequence of notificationType and subtype values our server should expect — from the moment we remove the product from sale through the subscriber's final expiration? Based on our research, we believe the sequence may be: (1) Cleared for Sale unchecked → (2) No immediate notification → (3) At next renewal attempt → EXPIRED with subtype PRODUCT_NOT_FOR_SALE Could you confirm whether this is correct, or provide the accurate sequence? 3. Whether DID_CHANGE_RENEWAL_STATUS is sent before EXPIRED Is a DID_CHANGE_RENEWAL_STATUS notification sent to our server at the moment of removal from sale, before the EXPIRED notification at the renewal date? If yes, what is the subtype of this notification? 4. Recommended server-side handling per notification For each notification in the sequence above, what is the recommended server-side action? For example: On EXPIRED with subtype PRODUCT_NOT_FOR_SALE → revoke entitlement immediately? On DID_CHANGE_RENEWAL_STATUS (if sent) → update status only, do not revoke entitlement yet? Sandbox testing limitations We have confirmed that the "Remove from Sale" setting does not affect the sandbox environment. Is there any recommended way to test this scenario before applying it in production? If sandbox testing is not possible for this case, is there any official confirmation of this limitation? We have a fixed service termination schedule and need to ensure our backend handles this correctly. Any clarification or pointers to official documentation would be greatly appreciated. Thank you.

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!

I have a VoIP app, now try to implement the new method which support the "PKVoIPPushMetadata" in iOS 26.4. Code as below: /// iOS 26.4+ (SDK with `PKVoIPPushMetadata`): prefer this path for VoIP per Apple; completion is `@Sendable` on supported SDKs. @available(iOS 26.4, *) func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingVoIPPushWith payload: PKPushPayload, metadata: PKVoIPPushMetadata, withCompletionHandler completion: @escaping @Sendable () -> Void) { print("willtest: didReceiveIncomingVoIPPushWith: metadata=\(metadata)") handleVoIPPush(payload: payload, metadataMustReport: metadata.mustReport, completion: completion) } func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) { print("willtest: didReceiveIncomingPushWith: PKPushType=\(type)") handleVoIPPush(payload: payload, metadataMustReport: nil, completion: completion) } But the voip push only goes to the old method on my iOS26.4 device(iPhone17). And it will go to the new method after I delete the old method. So how can I use this method in my app? I must support iOS16+ versions.

Hi everyone, I have developed an app that requires push notifications to notify users to respond to a questionnaire. After login, I inform the user that the app needs push notifications in order to function properly, and I request their consent to receive notifications. However, during the review process, Apple keeps rejecting the app with the following message: Issue Description The app requires push notifications in order to function. Next Steps Push notifications must be optional and must obtain the user's consent to be used within the app. Anyone knows how to fix this problem? Thank You

In my VoIP app, we use StartRing and StopRing via VoIP push to my app. But recently, I found some disordered VoIP notifications, my VoIP app received the StopRing push before the StartRing push. Examples: Server log: // send StartRing startring: - Apr 9, 2026 @ 14:54:43.255 .."pushType":"voip","priority":10, ... // send StopRing stop-ring Apr 9, 2026 @ 14:54:47.645 ..."pushType":"background","priority":5,"... VoIP app log: // receive StopRing 2026-04-0909:54:48.858 CDT : INFO : [RcRtc] [0x1feeba1c0] [PushNotificationParser]call push notification handled. action: StopRing telephony session id: s-a0dd8601926c7z19d72bbf8b9z1e62ec10000 sid: 178503189447188 // receive StartRing 2026-04-0909:54:49.524 CDT : INFO : [RcRtc] [0x1feeba1c0] [PushNotificationParser]call push notification handled. action: StartRing telephony session id: s-a0dd8601926c7z19d72bbf8b9z1e62ec10000 sid: 178503189447188 Then we can see the StartRing send first, but received in the app after the StopRing. The StartRing took abunt 6s to send and the StopRing took about 1s. So I guess there is an issue in the APNs part on iOS26.4. We saw there is a peak after iOS26.4 and iOS 26.4.1 than old iOS versions. Thanks.

Hello! I’m building a VoIP app for iPhone and Apple Watch using PushKit and CallKit. I’m trying to understand the recommended watchOS architecture for this kind of setup. What we would like is for the watch to behave as an endpoint for incoming calls, so that when a call comes in the user can answer on either the iPhone or the watch. My understanding is that VoIP notifications are not supported on watchOS, so for incoming calls what we ended up having to do was send the watch a regular APNs alert notification and only start the actual call setup after the user interacts with it. This isn’t ideal, and the notification often appears a few seconds late. What we would like to be able to do is present the incoming call on the watch more like how FaceTime calls appear on Apple Watch. So I wanted to ask whether this is the intended pattern for a companion watchOS VoIP app. Is using a regular APNs alert notification the correct way to surface an incoming call on the watch, or is there a better supported approach? Thanks!

I'm working on an app, and currently, 2 things dont work: account creation and notifications. I want to find the root of why these errors are occurring, and I want to know if these errors are coming from Firebase, certain settings in Xcode not being checked, or my actual written code not being typed correctly. I've tried to run my issue through ChatGPT many times to pretty much no success, so any help on what to do so I can clear certain areas and make sure the bugs aren't from certain spots, and help me narrow down the issue would be great. Otherwise, if there are other guides or threads I can be linked to, and help me fully break down the issue, that would be great. Thank you for your time reading, and I hope I can get some advice.

I am getting InvalidProviderToken for every APNs key I create under my team. This has persisted for over a week across 3 different fresh keys. Setup: Team ID: QJLCAXKWMB Bundle ID: com.trackntakeit.app All keys: Team Scoped, All Topics, Sandbox & Production JWT: ES256, correct kid and iss fields Tested directly from Mac via curl with fresh tokens The key file is a valid EC 256-bit private key. JWT is correctly formed. Both production and sandbox endpoints return InvalidProviderToken. Case number with Apple Developer Support: 102857626802 Has anyone seen all APNs keys for an entire team being rejected? Could there be an account-level block on APNs?

We have an iPhone app with a companion watchOS app for factory alert monitoring. What we want to achieve is: each server event is an independent event, not just a latest-state update events should not be dropped in some scenarios, new events may arrive as frequently as once per minute the watch app state/UI should reflect the event almost in real time our target is roughly within 5 seconds the watch app is expected to be opened by the user when they want to confirm details, but we want the data to already be there even if the watch app was previously in the background notification mirroring is already sufficient for immediate user awareness; the question is about reliable background data/state delivery to the watch app Our current architecture is: The server sends APNs pushes to the iPhone app. We use both: alert pushes for user-visible notifications background pushes (content-available: 1, apns-push-type: background, apns-priority: 5) for background data delivery When the iPhone app receives the push, it relays data to the watch using WatchConnectivity. On the iPhone/watch side: we use sendMessage when reachable / foreground-like communication is possible we use transferUserInfo as the background / unreachable fallback The devices are paired and connected, and the apps are not force-quit. In practice, the behavior is not stable enough for this requirement: some background deliveries are delayed some relays to the watch are not timely the end-to-end behavior is not reliable enough for independent event delivery with near-real-time expectations My understanding is that: APNs background pushes are not guaranteed and may be throttled WatchConnectivity background delivery is opportunistic immediate WC messaging depends on reachability / active state So the main question is not how to debug a single implementation issue, but whether our expectation is valid at all on Apple platforms. Questions: Is this architecture fundamentally unsuitable if the requirement is lossless, near-real-time event delivery from server -> iPhone -> watch, with a target of roughly within 5 seconds? Even if the implementation is correct, should we expect iPhone background push + WatchConnectivity relay to remain inherently non-deterministic for this kind of requirement, especially in scenarios where events may occur approximately once per minute? If notification mirroring is used only for user awareness, but the watch app still needs reliable background state/data delivery before the user opens it, is there any Apple-supported architecture for that? Would direct delivery to the watch app be the only realistic direction, or is this level of reliability/latency simply not a supported expectation for general-purpose apps? We understand that background execution and delivery are managed opportunistically by the system. What I want to confirm is whether this requirement itself is outside the practical/supported envelope of APNs background push + WatchConnectivity relay.

I’m experiencing a confusing issue with App Store Server Notifications (Version 2) in the Sandbox environment. I've configured my Sandbox URL, but I'm not receiving any notifications despite successful API responses. App Details: App ID: 6753059790 Bundle ID: com.xmojong.widgetTest Sandbox URL: https://webhook.site/97938287-07e8-4482-a053-b6ccfca76634 The Problem: I am calling the requestTestNotification endpoint via the App Store Server API. The API call is successful and consistently returns a 200 OK status code. However, no notification (Type: TEST) is ever delivered to my Webhook.site endpoint. What I've verified: Endpoint Accessibility: I tested the Webhook URL by sending a manual POST request directly from my iOS app; it was received instantly. Configuration: The URL is correctly entered in the Sandbox Server URL field (not Production) in App Store Connect. Notification Version: It is set to Version 2. Propagation Time: It has been over 3 hours since I updated the URL and saved the changes in App Store Connect. JWT Token: The JWT for the API call is valid (verified by the 200 response from Apple). My Question: If the requestTestNotification API returns a 200, doesn't that mean the App Store server has successfully queued the notification for my specific URL? Is there a known delay for Sandbox notification delivery or URL propagation recently? Or are there any hidden requirements for the Sandbox environment that I might have missed? Any help or insights would be greatly appreciated! Thanks in advance!

Hi all, I’m trying to determine whether the loudness gap I’m seeing between AlarmKit alert playback and normal app-managed playback is expected behavior, a sound-asset issue, or something that should be reported as a bug. Observed behavior When an alarm fires through AlarmKit while the device is locked, the alarm sound is significantly quieter than playback of the same or very similar audio once the app is active and using its own audio session. The difference is large enough that it does not feel like a small mastering difference. It feels like the AlarmKit / system alerting path is using a meaningfully lower effective output level than normal app playback. Test scenario My repro is roughly: Schedule an alarm with AlarmKit. Lock the device. Let the alarm fire and listen during the system alerting phase. Enter the app / continue into the app-driven alarm experience. Play the same or equivalent alarm asset via app-managed playback. Result: AlarmKit / lock-screen alerting phase sounds much quieter. In-app playback sounds noticeably louder and fuller on the same device. Current implementation Alarm flow is currently split into two paths: 1) System alarm path Alarm scheduling and alert surfacing via AlarmKit Device may be locked No attempt to manipulate system volume No private APIs 2) In-app playback path After app activation, playback uses: AVAudioSession category .playback AVAudioPlayer Audio is routed as normal app playback This path sounds substantially louder than the AlarmKit path Important detail I am not asking how to override system volume. I understand that AlarmKit appears to follow the system ringer / alert volume model and does not expose a public API for custom alarm loudness. My question is narrower: Is it expected that the same asset or an equivalent asset will sound materially quieter during the AlarmKit alerting phase than during ordinary app playback with AVAudioSession(category: .playback)? Questions Is the lower perceived loudness during AlarmKit alerting an expected property of the framework / system alarm path? Does AlarmKit playback use a different output path, gain policy, processing chain, or speaker treatment than normal app playback with .playback? Are there recommended authoring constraints for AlarmKit alarm sounds to maximize perceived loudness on iPhone speakers? transient-heavy mix stronger mids reduced low-end different LUFS / peak strategy shorter attack, etc. Has anyone measured this directly with: the same WAV / CAF file same device same system volume locked AlarmKit playback vs unlocked in-app playback If this is not expected, would Apple want this reported as a bug with: sample project exact iOS version device model screen recording / audio recording What I’m trying to figure out For alarm-app UX, this matters a lot because: AlarmKit is the most reliable lock-screen/system path. But if AlarmKit playback is substantially quieter than normal app playback, the alarm experience is inconsistent depending on device/app state. That makes it hard to know whether to treat this as: expected system behavior, a framework limitation, an asset/mastering problem, or a bug. If anyone has tested this in a controlled way or received guidance from Apple/DTS, I’d appreciate any technical detail. Thanks.

I am working on a large-scale e-commerce application and we are trying to solve a specific issue regarding push notifications and user experience. We have a use case where we need to send a standard push notification to the user, but under certain local conditions on the device, we want to intercept that notification via a Notification Service Extension and suppress/drop it so it does not alert the user. We understand that the com.apple.developer.usernotifications.filtering entitlement allows a Notification Service Extension to drop notifications. However, looking at the entitlement request form, the categories seem strictly limited to: End-to-end encrypted messaging Earthquake warnings Education/learning platforms Enterprise healthcare apps My questions for the community and Apple staff: Is it possible for an e-commerce or retail app to be approved for this entitlement if we have a highly specific, valid use case that improves user experience. If this entitlement is strictly off-limits for our domain, what is the Apple-recommended architecture to achieve this? Thank you in advance for any insights or guidance!

Are there some requirements to use Notification Content Extensions other than including the target to my iOS app? I have done it, configured it to match a certain category of notifications, but my custom interface doesn’t show up. is there anything I need to configure on my main app? Is that anything that should be changed there, such as disabking its botifications handling? is there any requirement concerning the payload? I tried to disable time sensitive and content-available notifications, but it didn’t help.

In my Notification Service Extension I'm doing two things in parallel inside didReceive(_:withContentHandler:): Downloading and attaching a rich media image (the standard content modification work) Firing a separate analytics POST request (fire-and-forget I don't wait for its response) Once the image is ready, I call contentHandler(modifiedContent). The notification renders correctly. What I've observed (via Proxyman) is that the analytics POST request completes successfully after contentHandler has already been called. My question: Why does this network request complete? Is it because: (a) The extension process is guaranteed to stay alive for the full 30-second budget, even after contentHandler is called so my URLSession task continues executing during the remaining time? (b) The extension process loses CPU time after contentHandler but remains in memory for process reuse and the request completes at the socket/OS level without my completion handler ever firing? (c) Something else entirely? I'd like to understand the documented behaviour so I can decide whether it's safe to rely on fire-and-forget network requests completing after contentHandler, or whether I need to ensure the request finishes before calling contentHandler.
