PTT Framework Restrictions
We are attempting to update our app to use the PTT framework, as it has been made clear that this will be required in a future iOS version as opposed to using the Unrestricted VoIP entitlement we are using for several features of our app. However, the behavior of this framework poses some problems with implementing our app's functionality: It is not possible to programmatically join a channel when the app is not in the foreground. This hinders our ability to implement the Automatically activate radio stream feature of our app, which allows users who have opted into this feature to immediately begin hearing live PTT audio from their agency following an incident alert. Having the app constantly "joined to a channel" and using the restoration delegate could potentially work, however this is not ideal as this would result in the PTT UI needing to be displayed at all times, even when no radio stream is activated. We have a "Text to Speech" option that, when enabled, reads out the content of an incident alert after the alert sound has played. This currently happens by triggering an AVSpeechSynthesizer in the PushKit incoming push callback. It may be possible to render TTS audio on the fly in a Notification Service Extension and assign it as the notification's sound, if that is possible this is less of a problem. We also use the PushKit callback to, again if the user has enabled it, activate a "Shake to Respond" feature, allowing a short period of time after receiving an incident alert in which the user can shake their device to indicate that they are responding to the incident. There does not appear to be any way to have the level of background execution required to implement this using an NSE, and this is of course beyond the scope of the PTT framework. What options do we have to be able to continue to provide this functionality, without risk of it being disabled in a future iOS version?

APNS Notifications not received on macOS Device
Hello Team, We are currently experiencing an issue where some of our devices are not receiving push notifications. We are sending notifications via the Apple Push Notification portal (https://developer.apple.com/notifications/push-notifications-console/) using the following two requests. However, in both cases, the notifications are not being delivered to the devices. Scenario 1 : When we send a request with apns-push-type set to alert, we receive the following error. Request : curl -v --header "authorization: bearer ${AUTHENTICATION_TOKEN}" --header "apns-topic: com.testcompany.sampletest" --header "apns-push-type: alert" --header "apns-priority: 10" --header "apns-expiration: 0" --data '{"aps":{"alert":{"title":"Test Notification Title","subtitle":"Test Notification Sub Title","body":"Test Notification Body"}}}' --http2 https://api.push.apple.com:443/3/device/*devicetoken* Response: { "code": 400, "message": "bad-request", "reason": "The device token is inactive for the specified topic. There is no need to send further pushes to the same device token, unless your application retrieves the same device token.", "requestUuid": "c4ae39b4-87e1-4269-a1e9-163f60ec0385" } Scenario 2 : However, if we send the request with apns-push-type set to background, the request is processed successfully by APNs, but no notification is received on the device. Request : curl -v --header "authorization: bearer ${AUTHENTICATION_TOKEN}" --header "apns-topic: com.testcompany.sampletest" --header "apns-push-type: background" --header "apns-priority: 10" --header "apns-expiration: 0" --data '{"aps":{"alert":{"title":"Test Notification Title","subtitle":"Test Notification Sub Title","body":"Test Notification Body"}}}' --http2 https://api.push.apple.com:443/3/device/*devicetoken* Response: Getting a message that The notification sent successfully but no notification is received on the device. In both cases (with alert and background push types), the push notification does not reach the device. Additionally, when we validated the device token using the APNs Device Token Validator, it appears to be valid and returns the following message. "Device Token is valid for sending Alert & Background push-type notifications in the Production environment" Affected Device: macOS version : MacOS 15.3.1 Processor : Apple M1 Could you please assist me in resolving this issue? Thanks

Push notification sent to uninstalled app
I am using push notification in my app. User token gets properly registered and is sent to server. Notification are also sent by server and recieved on device as expected. The problem occurs when user uninstalls the app. iOS does not provide any option to handle uninstall event. On top of that when server send notification to such device token APNS feedback service sends success message. Meaning APNS sends push notifications to uninstalled app.I have an API to unregister the device on server since no event is triggered I am unable to call it.Please suggest a way out.

Extend of notification content
In iOS 26, I can check the notification that arrives to the user when the AirPods or Apple Watch is fully charged. When tap the notification, notification only expands and does not include actions such as moving to an app. I checked the documents of UserNotification and UNNotificationServiceExtension, but I couldn't find what I wanted. I can expand by long-tapping as default, but I'm looking for a way to expand it without entering the app when I tap the notification. I wonder if there is an API that I missed or if it's not publicly supported. thank you for your support.

Failed to call ConversationManager.reportNewIncomingConversation in PushKit pushRegistry
Recently, I attempted to use LiveCommunicationKit to replace CallKit. The goal was to explore better features or integration. However, a major problem emerged. When the app is in the background or killed, it shows no notifications. This seriously impairs the app's communication functionality as notifications are vital for users to notice incoming calls. And it is working well when the app is in the foreground. When the app is in the background, when the push message received. the app get crashed with the following information: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push.' Also, when I use CallKit instead of LiveCommunicationKit, the app works well in all cases. The code is here: LCK wrapper: class LCKWrapper : NSObject, ConversationManagerDelegate { var mgr: ConversationManager var lckDelegate: LCKDelegate var currentCallId: UUID @objc init(handler: LCKDelegate, appName: String, appIcon: UIImage) { self.lckDelegate = handler var iconData: Data? iconData = appIcon.pngData(); var cfg: ConversationManager.Configuration cfg = ConversationManager.Configuration(ringtoneName: "ringtone.m4a", iconTemplateImageData: iconData, maximumConversationGroups: 1, maximumConversationsPerConversationGroup: 1, includesConversationInRecents: false, supportsVideo: false, supportedHandleTypes: Set([Handle.Kind.phoneNumber])) self.mgr = ConversationManager(configuration: cfg) self.currentCallId = UUID() super.init() self.mgr.delegate = self } func reportIncomingCall(_ payload: [AnyHashable : Any], callerName: String) async { do { print("Prepare to report new incoming conversation") self.currentCallId = UUID() var update = Conversation.Update() let removeNumber = Handle(type: .generic, value: callerName, displayName: callerName) update.activeRemoteMembers = Set([removeNumber]) update.localMember = Handle(type: .generic, value: "", displayName: callerName); update.capabilities = [ .playingTones ]; try await self.mgr.reportNewIncomingConversation(uuid: self.currentCallId, update: update) print("report new incoming conversation Done") } catch { print("unknown error: \(error)") } } } And the PushKit wrapper: @available(iOS 17.4, *) @objc class PushKitWrapper : NSObject, PKPushRegistryDelegate { var pushKitHandler: PuskKitDelegate var lckHandler: LCKWrapper @objc init(handler: PuskKitDelegate, lckWrapper: LCKWrapper) { self.pushKitHandler = handler self.lckHandler = lckWrapper super.init() let mainQueue = DispatchQueue.main // Create a push registry object on the main queue let voipRegistry = PKPushRegistry(queue: mainQueue) // Set the registry's delegate to self voipRegistry.delegate = self // Set the push type to VoIP voipRegistry.desiredPushTypes = [.voIP] } func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) async { if (type != .voIP) { return; } await self.lckHandler.reportIncomingCall(payload.dictionaryPayload, callerName: "Tester") } }

Delay in notifications iPhone 16 Pro iOS 18.3
Hi, I’m having issues with push notifications on my phone across multiple apps. When someone sends me a message, I only receive the notification 10 to 15 minutes later. For example, on WhatsApp, people say that my chat only shows one checkmark when they send me a message. I don’t know what else to do. I’ve already contacted Apple Support, visited an Apple-affiliated physical store, and followed all the recommended procedures. This is my first time using an iPhone—I bought it for professional use, but it’s practically useless if I don’t receive notifications instantly. They even told me that if I send it in for warranty service, there’s a 90% chance they won’t detect the issue, and the iPhone will come back with the same problem.

Can Critical Alerts Play Sound Continuously Until User Interaction?
We are developing an app that receives push notifications (via Firebase) from configured IoT devices. It is essential that when a specific type of notification is received, a sound is played continuously until the user interacts with the notification. This behavior is crucial for alerting users to certain critical states of the IoT device. We understand that Critical Alerts on iOS can bypass Do Not Disturb and silent mode. However, from our testing and available documentation, the sound from a Critical Alert seems to be limited to around 30 seconds. Our question: Is it possible on iOS to have a Critical Alert (or any other type of notification) continue playing sound until the user interacts with the notification or app? If so, could someone please point us to the appropriate documentation or APIs? Thanks in advance for any guidance.

Push payload is not present on notification tap
I am checking if the user taps on the firebase push notification and get the payload. override func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { let userInfo = response.notification.request.content.userInfo os_log("notification tapped %{public}@", log: OSLog.push, type: .info, userInfo) handleNotificationPayload(userInfo as! [String: AnyObject]) setFlutterLinkClickedVariable() } My use case is in app terminated state when push notification is tapped, get the link from payload and navigate to corresponding screen based on the link. This is working when there is only one push notification. When there are multiple push notifications with different links in the payload, only the first notification I tap works. Rest of the notifications just launches the app and does not navigate because the link is not set. I am getting the link from the payload and invoking flutter code which sets the link in the user defaults (shared preferences) and when the app launches in the home screen it checks for this variable and navigates accordingly. func handleNotificationPayload(_ payload: [String: AnyObject]) { if let link = payload["link"] as? String { setFlutterLinkVariable(link) } } override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { os_log("app did receive remote notification %{public}@", log: OSLog.push, type: .info, userInfo) handleNotificationPayload(userInfo as! [String : AnyObject]) completionHandler(.newData) } Currently when there is only one push notification it works because the link is set from the above method. The click delegate is not calling. I did set the delegate in application(:didFinishLaunchingWithOptions). UNUserNotificationCenter.current().delegate = self application.registerForRemoteNotifications() How to solve this issue? Thanks.

Critical Alerts and Notification Permissions
Back story: I'm developing an app that communicates with a personal medical device. We use critical alerts when we have hardware issues that could result in harm to the patient. The audio file is a 30 second file to make sure the patient is aware. If the app is open when they occur, we pop up a modal message in the app. When the user dismisses the notice, we call UNNotificationCenter::removeDeliveredNotifications(withIdentifiers:) to remove the critical alert and also to stop the audio file that is playing. This normally works fine. However we discovered that if the patient leaves critical alert enabled but disables notifications for our app, that we can still post the critical alert and it goes off. However when the user dismisses the message, the removeDeliveredNotifications call does not work. I did some debugging and if call getDeliveredNotifications with this permission combination, it return 0 (normally it would return 1). Does anyone know of another way to remove the critical alert in this situation? (or should I be submitting this as a bug?)

APNs Feedback Service Domain Unavailable
The APNs Feedback Service domain “feedback.push.apple.com” was deprecated on March 31, 2021, and became unavailable after August 2025 due to domain name resolution failures. Will this feedback service become available again in the future? Also, is it possible to use the APNs Feedback Service with a domain different from “feedback.push.apple.com”?

UNNotificationRequest set timestamp to a relative time
The system calendar when showing a calendar event shows a relative timestamp on the notification versus all other apps which have a timestamp of when the notification was sent. Is there a way to set the timestamp to be relative? I am currently working on a calendar app and we should be able to use the same system that apple uses for its own calendar. Post about this on stack overflow from someone else a few years ago

Expected behavior for a Notification Service Extension with notification filtering when requestAuthorization has not been requested
If there is a Notification Service Extension which has the com.apple.developer.usernotifications.filtering entitlement, then does/how having that entitlement affect the preconditions for the NSE to be delivered a push? Specifically, if the app has not prompted for requestAuthorization() is it expected that the push will be delivered to the NSE or not? Thank you
