I am planning to run the AccessoryNotifications framework on xcode26.4 and ios26.4, please refer to the documentation https://developer.apple.com/documentation/accessorynotifications I couldn't find a complete demo, but I found a demo based on AccessorySetup Kit, ASK Sample https://docs-assets.developer.apple.com/published/89f5eef578ef/SettingUpAndAuthorizingABluetoothAccessory.zip. So I plan to practice the entire process of AccessoryNotifications based on this demo. Find accessories based on ASK Sample and connect them, OK Call requestForwarding (for:), OK Add AccessoryData Provider extension to receive system notifications But this step failed. I added an extension according to the documentation, but the following method will not be executed func activate(for session: NotificationsForwarding.Session) func add(notification: AccessoryNotification alertingContext: AlertingContext, alertCoordinator: AlertCoordinating) {} I found the following error log in console.app Error 16:38:17.582340+0800 usernotificationsd ### XPC DAEventExtension decode failed: DAExtensionSession: CID 0x89B80004, DAExtensionSessionConfiguration 'AB83C506-9F35-40FB-9A68-919D43B4D098': BundleID 'com.sifli.ASKSample', DAErrorDomain:350001 'DAExtensionEvent init bad type: 42' I have tried many methods to send messages to the testing phone, local Notifications, We can't even trigger the AccessoryData Provider, activate:for,add:notification: 1.Do I have to add the following two extensions according to the document in order to debug successfully?

Hello, I'm from Microsoft team maintaining push notification api behind Teams platform. We are experiencing strange and short error spikes towards APNS that seem to mostly correlate worldwide. We checked the networking and push request code but could not find what could be causing this. These error spikes are all timeouts or connection resets (by remote host, ie. APNS servers) and seem to come and go randomly: Would it be possible to check this for outages or some other metrics on your side or investigate why would it happen? Since it's worldwide it seems unlikely it's something broken on our side. We are using the standard APNS http2 endpoint with modern support for all RFC features (so everything should work normally). Mind you, our api might be in a unique position because of the volume of notifications (in the billions per day).

Hello, We are experiencing an issue related to push notifications after updating devices to iOS 26.4 Beta. Our system stores push notification tokens on the server by associating the device token with the device’s IDFV in the app. After updating a device to iOS 26.4 Beta, we observed that the device token from a previously uninstalled version of the app remains valid for more than a week. As a result, two push notifications are delivered to the same device. The situation is as follows: The user installs the app and a device token is generated. The user uninstalls the app. Later, the user installs the app again and a new device token is generated. However, the previous device token does not become invalid, even after more than a week. Because IDFV changes when the app is reinstalled, our server cannot determine that the device belongs to the same user. Therefore, we cannot overwrite the old token with the new one on the server side. Could you please advise: Is this behavior expected in iOS 26.4 Beta? How long does it normally take for a device token to become invalid after an app is uninstalled? What is the recommended approach to prevent duplicate push notifications in this situation? Any guidance would be greatly appreciated. Best regards

I am currently encountering an issue: when creating a new push certificate on the Apple Push Notification Certificates portal, I am required to generate a signature beforehand. Could you please explain the specific rules for this signature and how I should go about generating it? (I previously attempted to generate the certificate using the following command—openssl req -new -key mdm_push.key -out mdm_push.csr—but after uploading it, I received an error indicating an incorrect format.) !

I have a messaging app that has been working successfully for several years. It still works for most users, but about one month ago one of my users started experiencing issues receiving notifications. From my investigation, the user's Notification Service Extension (NSE) has not been triggered since they started reporting the issue. I was able to access the user's phone and connected it to the console to check for any logs related to the NSE being triggered or a push notification being received, but there were no relevant logs. I have already verified that notifications are enabled for the app and that Do Not Disturb is not active. I also tried sending a test notification using the CloudKit Console. The notification was successfully delivered to other push notification tokens, but it did not work for this specific device’s token. I have also confirmed that the push token on the server matches the one on the device and that it is being used with the APNs production environment. The issue for this user started in iOS version 26.2 and are still ongoing in version 26.3.1 . Has anyone encountered a similar issue or have suggestions on how to further diagnose this?

Hello everyone, I’m an iOS developer working on a real-time communication app that supports VoIP calls using CallKit. The app has been in production for more than 5 years. Over the years, some users have occasionally reported that they do not receive incoming call pushes. We have tried multiple optimizations on both the client and server side, but the improvement has been limited. From Apple documentation and discussions online, I understand that iOS may restrict VoIP pushes if the system detects violations of VoIP push usage rules (for example, not presenting a CallKit call after receiving a VoIP push). However, the exact rules and thresholds for these violations are not clearly documented, so I’d like to ask a few questions to better understand the expected behavior. Below is a simplified description of our current call flow. Call Flow Caller When the user initiates a call: We do not use CallKit The call is handled entirely using a custom in-app call UI Callee When the user receives a call: Device locked or app in background A VoIP push wakes the app The app presents the CallKit incoming call UI App in foreground The server still sends a VoIP push The app first reports the call to CallKit After a very short delay, the app programmatically ends the CallKit call Then a custom in-app call UI is presented via the app's long connection The reason we always send a VoIP push (even when the app is in the foreground) is that we want to maximize call delivery reliability.

Environment: iOS 26.4 beta Xcode 26.4 beta Framework: AccessoryNotifications, AccessorySetupKit, AccessoryTransportExtension Description: I'm implementing notification forwarding to a custom BLE accessory using the new AccessoryNotifications framework in iOS 26.4. I've set up an AccessoryDataProvider extension following the documentation, but I'm unclear about how the data is actually transmitted to the BLE accessory. Current Implementation: Main App - Uses AccessorySetupKit to discover and pair accessories: let descriptor = ASDiscoveryDescriptor() descriptor.bluetoothServiceUUID = CBUUID(string: "FEE0") let displayItem = ASPickerDisplayItem( name: "Notification Accessory", productImage: UIImage(systemName: "applewatch")!, descriptor: descriptor ) accessorySession.showPicker(for: [displayItem]) { error in // Handle error } AccessoryDataProvider Extension - Implements NotificationsForwarding.AccessoryNotificationsHandler: @main struct AccessoryDataProvider: AccessoryTransportExtension.AccessoryDataProvider { @AppExtensionPoint.Bind static var boundExtensionPoint: AppExtensionPoint { Identifier("com.apple.accessory-data-provider") Implementing { AccessoryNotifications.NotificationsForwarding { NotificationHandler() } } } } // NotificationHandler sends messages via: let message = AccessoryMessage { AccessoryMessage.Payload(transport: .bluetooth, data: data) } try await session?.sendMessage(message) Info.plist Configuration: EXExtensionPointIdentifier com.apple.accessory-data-provider NSAccessorySetupBluetoothServices FEE0 Questions: What BLE Service and Characteristic should the accessory advertise? - The documentation mentions specifying transport: .bluetooth, but doesn't explain what Service/Characteristic the accessory needs to implement to receive the notification data. 2. How does AccessoryMessage with transport: .bluetooth actually transmit data? - Is there a specific Apple-defined BLE protocol? - Does the accessory need to run specific firmware or support a particular protocol stack? 3. Is there any documentation about the accessory-side implementation? - The iOS-side documentation is clear, but I couldn't find information about what the BLE peripheral needs to implement. 4. Is MFi certification required for the accessory? - The documentation doesn't explicitly mention MFi, but it's unclear if custom third-party accessories can use this framework. Any guidance on how the BLE communication works under the hood would be greatly appreciated.

We recently developed the provisional permission for our app, but we have noticed that is not working as expected in iOS 16 (We have tested only there). Currently we request the permissions like this: UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound, .provisional]) { [weak self] _, _ in // here we register for pushes in case authorizationStatus is provisional or authorised } What happens is we do get the 1st notification with the keep CTA - once tapped we see that there pops an action: "Deliver Immediately", but even though the user selects that, we still see under setting the pushes are marked as "Deliver Quietly". In addition to this the sound and bage still stay as toggled off - and the lock screen and banner as well stay off. Basically, nothing changes after the user selects "Deliver Immediately"

I'm working on an app that syncs with Apple Health events. Every time an event occurs, the app should send a notification. The problem occurs when the app is backgrounded or force-closed; it can no longer send local notifications, and because these events can occur at any time, scheduled notifications can't be used. I'm just wondering if anyone's found a creative way around this. I know we can't override system behaviour, I'm just thinking of other alternative solutions for the matter.

The APP was not awakened by system after start a liveactivity and the liveactivity has showed on lock screen.so the updatetoken wont send to our inner server and the liveactivity can not update,often like this,but sometimes it can work. it makes me confuse,and i don't know how should i can do,because the liveactivity like a black box,i can not analyse the data link.for example ,inner server send a start liveactivity,but it can not accept a updatetoken unless the user lanuch APP. i hope the liveactivity can start and update on background. And i have developed it as described in the document. Hope to get your help，thank you very much.

Since upgrading to Xcode 26 beta 4 and using the iOS 26 simulator for testing our app, we've stopped being able to receive device tokens for the simulator from the development APNS environment. The APNS environment is able to return meta device information (e.g. model, type, manufacturer) but there are no device tokens present. When running the same app using the iOS 18.5 simulator, we are able to register the device with the same APNS environment and receive a valid device token.

Having voice control enabled now puts three menu bar items. The blue icon it has always had, supplemented with an orange microphone and an orange dot next to control center. I know this orange icon is there to notify me that a third-party application is accessing the microphone, but this is a first-party system service that is always running. If another app starts accessing the microphone I won't know, since the orange icon is always there anyway. It's like a California prop 65 warning. Maybe it was a good idea in principal but with it being ubiquitous everyone just ignores it. Siri is also always accessing the microphone, but doesn't trigger this orange eyesore because it's a system service. Both Siri and voice control are always on in the background, are first-party system services that must be specifically enabled, and both have their own menu bar icon that can be removed if not wanted. This orange icon with voice control potentially introduces MORE risk by training me to ignore the orange icon. Please return to the pre-26.3 behaviour of using this orange icon for third-party apps and not first-party system services. FB22036182 -- "Voice control causes extra menu bar icon"

I am developing a VoIP service. Usually, when receiving a VoIP Push, Callkit is exposed immediately after receiving the message and the app is designed to be used. However, there is an extremely intermittent phenomenon (not well reproduced) where the app does not wake up even when receiving a VoIP Push. And after a long time, the app wakes up and Callkit is activated. (A long time after receiving the call…) Has anyone experienced the above phenomenon? I wonder if there are any reported parts depending on the OS version. (I have identified that it does not occur in the 17.x version, but it is difficult to guarantee because it occurs extremely intermittently) The app is not running in the background, but... Could this be happening if there are a lot of pending operations in the background? I need help urgently

I am developing an application that uses NetworkExtension (Local PUSH function) And VoIP(APNs) PUSH. Nowadays, I found a problem on this app doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an APNs PUSH. My confimation result of my app and server log is below. 11:00 AM: my server(PBX) requests a VoIP(APNs) PUSH notification to the APNs. But my app does not receive the VoIP(APNs) PUSH. At this time, my app is running on LAN (Wi-Fi without internet connection), as a result, NetworkExtension was running. so I think this is normal behaviour. 14:55:11 PM: There is an incoming call from the my server(PBX) via local net, and NetworkExtension calls iOS API(API name is reportIncomingCall). However, iOS does not call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall. 14:55:11 PM: At almost the same time, iOS calls the delegate cdidReceiveIncomingPushWithPayload of VoIP PUSH. (instead of call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall?) And the content of this VoIP(APNs) PUSH was the incoming call at "11:00 AM". In other words, the VoIP(APNs) PUSH at 11:00 AM is stuck inside iOS, and at 14:55:11 PM, from NetworkExtension reports it. I feel there is a problem on iOS doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an VoIP(APNs) PUSH. Would you tell me Apple's opioion about this? If this is known problem, Please tell me about it.

Hi, am facing an issue related to voip push notifications getting delivered 1-2 hours after apns-expiration to 0 and apns-priority to 10. I had raised a similar post got a reply that it may be due to network delay. But network delay can cause the delivery of voip push to be delayed only by few seconds or minutes. But in our case voip push is getting delivered hours after the voip call was attempted. Steps to reproduce: Put our voip app in background and lock iPhone. As app is put in background, socket connections gets disconnected from server. Now if a caller makes call to this app, the call should be delivered through voip push. 2) Voip push should ideally be received even if app is in background and iPhone is locked. It is connected to a good wifi network. But it does not receive the voip push. 3) After 1-2 hours user unlocks iPhone and opens voip app. As soon as user opens app, the voip push is received and phone starts ringing.

Hello, We are facing issue that sometimes a voip notification gets delivered after it is expired. The issue can be simply demonstrated we set the device to flight mode, and after 20s we disable flight mode. We still receive the voip notification. We are setting the expiration header as following apns-expiry=0, so from my understanding it should not be delivered if the device was not able to receive the notification in the fist attempt. I have read following thread https://developer.apple.com/forums/thread/778512, from which I understand this is a long standing issue. Hence my question is, is there any way how we can notify the call kit that the call is actually no longer valid, and do not display the call to the user at all? Currently we are forced to always display CallKit call when the notification comes, and some of our users are confused that they see a missed call which they did not have any chance to pick up. Please let me know if you need any more information. Best Regards, Adam Chlupacek

In didFinishLaunchingWithOptions I have this setup for getting the token to send to my server for notifications. The issue is that the delegate callback didRegisterForRemoteNotificationsWithDeviceToken gets called twice when also initializing a CKSyncEngine object. This confuses me. Is this expected behavior? Why is the delegate callback only called twice when both are called, but not at all when only using CKSyncEngine. See code and comments below. /// Calling just this triggers `didRegisterForRemoteNotificationsWithDeviceToken` once. UIApplication.shared.registerForRemoteNotifications() /// When triggering the above function plus initializing a CKSyncEngine, `didRegisterForRemoteNotificationsWithDeviceToken` gets called twice. /// This somewhat make sense, because CloudKit likely also registers for remote notifications itself, but why is the delegate not triggered when *only* initializing CKSyncEngine and removing the `registerForRemoteNotifications` call above? let syncManager = SyncManager() /// Further more, if calling `registerForRemoteNotifications` with a delay instead of directly, the delegate is only called once, as expected. For some reason, the delegate is only triggered when two entities call `registerForRemoteNotifications` at the same time? DispatchQueue.main.asyncAfter(deadline: .now() + 4) { UIApplication.shared.registerForRemoteNotifications() } func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { print("didRegisterForRemoteNotificationsWithDeviceToken") }

Hello Apple Developer Support, We are observing inconsistent behavior with push notification sounds routing to Bluetooth / external speakers. Our app sends push notifications with a custom sound file using the sound parameter in the APNs payload. When an iPhone is connected to a Bluetooth speaker or headphones: On some devices, the notification sound plays through the connected Bluetooth/external speaker. On other devices, the notification sound plays only through the iPhone’s built-in speaker. We also tested with native apps like iMessage and noticed similar behavior — in some cases, notification sounds still play through the phone speaker even when Bluetooth is connected. Media playback (e.g., YouTube or Music) routes correctly to Bluetooth, so the connection itself is functioning properly. We would like clarification on the following: Is this routing behavior expected for push notification sounds? Are notification sounds intentionally restricted from routing to Bluetooth in certain conditions (e.g., device locked, system policy, audio session state)? Is there any supported way to ensure notification sounds consistently route through connected Bluetooth/external speakers? The inconsistent behavior across devices makes it difficult to determine whether this is by design or a configuration issue. Thank you for your guidance.

Hello! We've had reports of iOS devices 'waking up' and vibrating in response to the push notifications arriving but the notification itself is not being displayed to the user, despite having been granted the correct permissions. Is this a known issue?

Hello, I am developing a driver-based application targeting iOS 14+, where users receive time-sensitive trip offers (approximately 10–15 seconds to respond). We would like to implement behavior similar to approval-based apps (e.g., MyGate-style interaction), with the following requirements: When the device is locked: A highly visible notification that allows quick Accept / Decline action. When the device is unlocked (foreground or background): A notification that remains prominently visible (sticky-style) at the top of the screen until the user takes action (Accept / Decline) or the offer expires. Our goal is to ensure the offer remains noticeable and actionable within the short response window. I would appreciate clarification on the following: On iOS 14, is there any supported mechanism to present a true full-screen blocking interface while the device is locked (without using CallKit or Critical Alerts entitlement)? Is there a supported way to make a notification persistent or non-dismissible until the user takes action or the offer expires? Are there any App Review concerns with presenting a blocking modal immediately after the user interacts with a notification? We want to ensure full compliance with Apple’s platform guidelines and avoid unsupported or discouraged patterns. Thank you for your guidance.
