Question, if I am writing async code in the notification service extension, I understand it terminates after 30 seconds. If I want to wait until these async methods finish before calling the content handler, I believe an option I have is to use dispatch groups. However I am open to other solutions if there are better options. My question is, if I use dispatch groups, is there any issue in using the main queue here? Or does the main thread not make sense to use in the context of the NSE? dispatch_group_notify(group, dispatch_get_main_queue(), ^{ if (self.contentHandler) { self.contentHandler(self.bestAttemptContent); } }); Or is it recommended to instead use a different queue in the NSE? dispatch_queue_t nseQueue = dispatch_queue_create("com.blah.blah.nse.queue", DISPATCH_QUEUE_SERIAL); dispatch_group_notify(group, dispatch_get_global_queue(QOS_CLASS_(SOMETHING), 0), ^{ ... }); OR am I over thinking this? :) Thanks ahead of time, relatively new to iOS so just looking to learn/understand better.

From iPhone iOS 18.3 , 18.3.1, and 18.4 Dev2, VIP Mail alerts will not wake a phone display to notify of a new mail received for a VIP contact. The phone will sound an audible tone indicating the mail was received, and if you manually wake the screen by tapping and then dragging upward to show notifications you will then see the VIP mail alert. However if the screen is sleeping, it will not light up or wake to indicate or display the new mail. The problem was briefly resolved in 18.4 Dev1, but problem returns in Dev2. We see this across all iPhone 16 Pros and iPhone SE2 with iOS 18.3 or higher. Is this something acknowledged by Apple as on track for resolution in iOS 18.4 Final Release? Thank you.

I have tried setting a 'apns-expiration' to current time + 30 seconds and also a value '0'. But still my voip app receives the voip push notification after 2-3 minutes. Till this time, caller has already hung up the call. But the receivers phone still rings on receiving the push notification as we have to report it to CallKit. Am I missing something or there is no way and even 'apns-expiration' does not guarantee timely delivery of Voip push notifications or discard if it is expired. I have set 'apns-priority' to 10 already as recommended.

I submitted the form for the critical alert entitlement but have not received any response for already 2 weeks. How long does it normally take to review such requests? Is there any way I can contact a certain department directly?

I want to update my lockscreen LiveActivity via Broadcast Push Notification, but updating always fails - but ending always works. Payload with "update" is completely ignored: {"aps":{"timestamp":1685952000,"event":"update","content-state":{"currentSlotName":"Debug1","nextSlotName":"Debug2"}}} Same payload with "end" works, the view is refreshed with the new content-state: {"aps":{"timestamp":1685952000,"event":"end","content-state":{"currentSlotName":"Debug1","nextSlotName":"Debug2"}}} Via the MacOS Console I am able to see that both events happen to end up on the device. I am sending these Broadcast Push Notifications via Apple's Push Notifications Console.

iOS push notification is not working for in App since 03-Apr-2025. We are pushing the message to APNS from our application, but message is not delivered to iOS device. We have performed tests on both PROD and QA environment and following are the observations: PROD successfully pushing the notification to APNS but not receiving the notification on iOS device (100% failure). QA received notification on iOS device always (100% success). Analyzed PROD notification server log at our end and we do not observe any error and it is showing successful also when message is pushed to APNS all the time. Need to check from APNS why push messages are not delivered to iOS devices. Validated the PROD APNS certificate at our end which we are using during call to APNS - it is valid till Oct 2025. Please suggest me any possible solution because I don't have any clue where it is failing and what to do

Hello, I am working on a project that involves using external device to connect over BLE with users iPhone. I would like to be able to notify users on our device about eg. incoming calls, messages etc. I have been succesfull in using ANCS to achieve that but I am a little worried around consistency of this solution, especially taking into account following line from documentation: Due to the nature of iOS, the ANCS is not guaranteed to always be present. As a result, the NC should look for and subscribe to the Service Changed characteristic of the GATT service in order to monitor for the potential publishing and unpublishing of the ANCS at any time. I have not been able (yet?) to find or identify circumstances when ANCS would not be avilable or would be "removed in runtime", hence would it be possible to request some guidance and clarification on the conditions when ANCS can be unavailable or removed? Thank you!

We're experiencing an issue with Apple Push Notification service where APNs continues to return 200 OK responses for device tokens belonging to uninstalled applications. Issue Details: When sending push notifications to device tokens. APNs returns 200 OK responses even for devices where our app was uninstalled more than a month ago According to documentation(https://developer.apple.com/documentation/usernotifications/handling-notification-responses-from-apns), APNs should return 410 status code with JSON body for invalid tokens Expected Behavior: APNs should return 410 status code when device token is no longer valid (app uninstalled) Thanks in advanced for support

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.

I'm trying to rewrite a Swift code to Swift 6 language mode and am stuck with this problem. How do I safely pass the bestAttemptContent and contentHandler to the Task? This is from the UNNotificationServiceExtension subclass. final class NotificationService: UNNotificationServiceExtension { var contentHandler: ((UNNotificationContent) -> Void)? var bestAttemptContent: UNMutableNotificationContent? var customNotificationTask: Task<Void, Error>? override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { self.contentHandler = contentHandler bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent) guard let bestAttemptContent = bestAttemptContent else { invokeContentHandler(with: request.content) return } do { let notificationModel = try PushNotificationUserInfo(data: request.content.userInfo) guard let templatedImageUrl = notificationModel.templatedImageUrlString, let imageUrl = imageUrl(from: templatedImageUrl) else { invokeContentHandler(with: bestAttemptContent) return } setupCustomNotificationTask( imageUrl: imageUrl, bestAttemptContent: bestAttemptContent, contentHandler: contentHandler ) } catch { invokeContentHandler(with: bestAttemptContent) } } // More code private func downloadImageTask( imageUrl: URL, bestAttemptContent: UNMutableNotificationContent, contentHandler: @escaping (UNNotificationContent) -> Void ) { self.customNotificationTask = Task { let (location, _) = try await URLSession.shared.download(from: imageUrl) let desiredLocation = URL(fileURLWithPath: "\(location.path)\(imageUrl.lastPathComponent)") try FileManager.default.moveItem(at: location, to: desiredLocation) let attachment = try UNNotificationAttachment(identifier: imageUrl.absoluteString, url: desiredLocation, options: nil) bestAttemptContent.attachments = [attachment] contentHandler(bestAttemptContent) } } } I tried using the MainActor.run {}, but it just moved the error to that run function. The UNNotificationRequest is not sendable, and I don't think I can make it so. Wrap the setupCustomNotification in a Task will move the errors to the didReceive method. It seems like the consuming keyword will help here, but it leads to a compilation error, even with the latest Xcode (16.2). Any pointers?

My Mac app has a launch agent (within the app bundle) that works great without the app running. There are some occasions where I need to display an alert and ask the user to launch the app to handle the issue. I thought about using UNUserNotificationCenter but I'm not able to make it work from the agent. I'm asking for authorization as follows: [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) { NSLog(@"authorization request completion. Granted: %@, error: %@ (%@)",granted?@"YES":@"NO",error, [error localizedDescription]); }]; And I'm trying to post the notification as follows: content.title = @"Your App Name"; content.body = @"Click the button to open the app"; content.sound = [UNNotificationSound defaultSound]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:[[NSUUID UUID] UUIDString] content:content trigger:nil]; [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { if (error) { NSLog(@"Error showing notification: %@ %@", error, [error localizedDescription]); } }]; When running I'm getting asked to authorize, I authorize and all seems OK in system settings but I'm not able send any notifications. addNotificationRequest results in UNErrorCodeNotificationsNotAllowed error. I tried this with the authorization request inside the main app, or inside the agent, with the same results. When trying to post the notification from within the app, it does work, but that's not what I need. Is posting notifications from within the launch agent not possible at all, or is there anything here that I'm missing. TIA

I have my app configured as a Driving Task app with the entitlement and provisioning profile correctly set up. I am also requesting the ".carPlay" notification authorization option and setting up the carplay notification category with the ".allowInCarPlay" category, both without error. When testing with the iPhone and carplay simulators the user notifications I send are appearing on the phone but not in carplay. When I check the notification settings with UNUserNotificationCenter.current().getNotificationSettings() I see that carplay is shown to be not supported ("carPlaySetting: NotSupported"). The CarPlay Developer Guide 2025-06-09 (which is the version currently referenced in the Apple docs) states that "Starting in iOS 18.4, notifications are also supported in CarPlay driving task apps". Has this discrepancy been addressed anywhere, or is this an open issue? My software versions: MacOS: Sequoia 15.6 XCode: 16.4 iPhone Simulator: iPhone 16 with iOS 18.6

We are in the process of transferring our app to a new Apple Developer Organization account. Our app uses the Apple Push Notification service (APNs) with a .p8 authentication key configured on our server to send push notifications. We would like to confirm: Once the app transfer is completed, will push notifications continue to work temporarily using the existing .p8 key on our server, until we generate and configure a new .p8 key under the new organization's account? Understanding this behavior is critical for us to ensure a smooth transition and avoid any disruption in push notification delivery for our users. Thank you for your guidance and support.

I am sending push notification using HTTP/2 to https://api.push.apple.com:443 api but I am getting Operation TimeOut error in response . Can someone help

Can I using AudioServicesPlaySystemSound for play sound os system on NotificationService?

I am experiencing an issue with push notifications on my iOS application. The issue is as follows: On Android devices, push notifications are received immediately without any problems. On iOS devices, the behavior is inconsistent: When the app is in the foreground, notifications are received immediately. When the app is in the background or in recent apps with a significant delay of 5–10 hours, push notifications are not received at all. This behavior creates a major challenge for us, as timely notifications are critical for our app’s functionality. We have already verified the following points on our side: Push notification certificates and APNs setup are correct. Payload and server configurations are valid, as notifications are working fine on Android. No restrictions from the server-side, since Android users receive notifications instantly. It seems the issue is specifically related to iOS devices or APNs delivery. Could you please help us identify the cause and provide guidance on how to resolve this?

Observations​​: When our app calls the APNs API for push notifications, we observed significant fluctuations: July 15-25​​: The success response volume ​​increased by 20%​​ compared to the baseline before July 15. ​​After July 25​​: Success rates returned to baseline levels. July 30​​: Success response volume ​​decreased by 10%​​ compared to the pre-July 15 baseline. ​​ Excluded Factors​​: No changes in target audience size or characteristics (business factors ruled out). Server logs confirm consistent API request parameters and frequency. ​​Key Questions​​: Were there any ​​adjustments to response metrics​​ (e.g., success status code definitions) during this period? Have other developers reported similar issues? Were there server-side configuration updates or known incidents on Apple’s end?

User is using my app, the goes to System Settings, and changes some of my App's settings (switches, text fields, etc). Does the system send my app any kind of notification? David PS: I tried all kinds of searches on this and found nothing.
