APN's not delivering to macOS devices
Hello, I am building a swift macOS app and have noticed issues today with delivering APN's to both development and production devices. Similar to this thread the only way I can get them to deliver temporarily is to do one of: Change the bundle ID of my app to a new bundle ID, then start it up. I will usually get the first notification. Reset my network (either wired ethernet or wifi, typically both) Using the push notifications console for development sends, I see the message "discarded as device was offline" in the delivery log even though the device is still online and was just registered when I got back the deviceToken. If I set an expiration on development notifications then the delivery log says "stored for device power considerations" and the notification will then send once I do one of the above steps (new bundle or reset network). Previous to today the notifications were sending immediately and I had no issues getting them. Is there something I can do to fix this problem, is it a problem with the APN provider, or is it something else I haven't thought of? A unique ID for an expiration-based notification is 1755def8-1a44-cbcf-c64b-64e435c30f81, and a non-expiry is d7a72b46-0c64-4500-0abc-3734f9efbd90.

Several pushes and lifetime
Hello everyone. I'm trying to add a lifetime for push notifications via apns-expiration for my application. With the Internet turned on, push notifications come, that's ok. With the Internet turned off, as I noticed, only the last push with the badge installation on the application icon comes. That is, the logic is that a text push with text is sent, then after N time the next push to the same device with the badge installation. I would like to receive a text push after turning on the Internet.

Apple Push Notification service's Certification Authority (CA) update
As you announced at this link https://developer.apple.com/forums/thread/766788, 'APNs will update the server certificates in sandbox on January 20, 2025, and in production on February 24, 2025.' I guess you have updated the sandbox certificate. What can we do to test whether we have correctly updated our application’s Trust Store to include the new server certificate.We test on a server that haven't updated the new server certificate, connect your sandbox environment 'api.sandbox.push.apple.com' to send notifications, it succeed. As I guess, it should failed.

I don't understand apple store server to server notification
Hello, I'am trying to validate a new app from apple. I have configured sandbox url and production url for server to server apple store notification. I have created subscriptions product id, but there are no validated yet by apple. When I upload my app to testflight, I can't test sandbox notification cause the product id are not available, on local xcode with storekit file I got my product Id but I don't receive notification. So my question is how can I test there thing. I have to produce fake product id ? I'm lock its very complex process, I don't understand. I tried to send my app like that for verification but the team told me to use receipt, but its deprecated and notification webhook is better for me. What is the good order, validate my subscription product ID then test ? what is the good steps. Apple seems to don't want validate my subscription product ID I'm lock..

watchOS Standalone App Notification Settings Not Appearing
I'm having an issue on my standalone watchOS app where the settings to adjust notifications does not appear anywhere on the iPhone or the Watch. I have successfully requested notifications access from the user and have successfully displayed a local notification to them. However, if the user ever decides to revoke my notification access (or if they deny originally and want to change), the settings pane for notifications does not appear anywhere. I've looked in the following places: On the watch in Settings > Notifications, however it looks like you can no longer edit per app notification settings directly on the watch (none of the installed apps on my watch appear in here). The only options are settings like "tap to show full notification" and "announce notifications" which affect all notifications (Why not? Especially for apps that don't have a iPhone companion app?). On the iPhone in the Watch app (the app you set up your watch in), in Watch > Notification. My app does not appear anywhere in there. On the iPhone in the iPhone Settings app, in Settings > Notifications. My app does not appear anywhere in there. On the iPhone in the iPhone Settings app, in Settings > Apps. My app does not appear anywhere in there I've tried: Adding capabilities in Signing & Capabilities for Push Notification, Time-Sensitive Notifications and Communication Notifications Building the app for release instead of debug My app also requires location access and has successfully appeared in the settings pane directly on the watch in Settings > Privacy & Security > Location Services, however notification settings do not appear anywhere. I have created a stripped down test app to try and that also does not work. This test code successfully asks the user for permission and (from a button in ContentView), successfully schedules a notification and displays it to the user when they're not in the app. Here's the code for my NotificationManager: import UserNotifications class NotificationManager: NSObject, ObservableObject, UNUserNotificationCenterDelegate { static let shared = NotificationManager() @Published var hasAuthorisation = false private override init() { super.init() UNUserNotificationCenter.current().delegate = self requestAuthorisation() } func requestAuthorisation() { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { authorised, error in DispatchQueue.main.async { if let error = error { print("Error requesting notifications: \(error.localizedDescription)") } self.hasAuthorisation = authorised } } } func scheduleNotification(title: String, body: String, timeInterval: TimeInterval) { let content = UNMutableNotificationContent() content.title = title content.body = body content.sound = .default let trigger = UNTimeIntervalNotificationTrigger(timeInterval: timeInterval, repeats: false) let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger) UNUserNotificationCenter.current().add(request) { error in if let error = error { print("Error scheduling notification: \(error.localizedDescription)") } else { print("Notification scheduled successfully.") } } } } This issue has persisted across two iPhones (recently upgraded) and the watch was wiped when connecting to the new iPhone. Am I missing some code? Am I missing some flag I need to set in my project somewhere? Please can someone with an Apple Watch try this code in a standalone watchOS app and see if the notifications pane appears anywhere for them? I've contacted Apple DTS, but they're taking a while to respond.

push notification on capacitor ios app with firebase or apnotic
Hi, I'm working on an IOS app using capacitor. I'm trying to receive push notifications on my downloaded app from testflight. I tried with FCM and it's working on my android app but not on ios and the logs show no error. This is how I retreive the FCM token: const fcmToken = await FCM.getToken() sendSubscriptionToBackEnd({ fcm_token: fcmToken.token, device: platform }) Then I have a job on my backend to send the push notifications: def perform fcm = FCM.new( StringIO.new(Rails.application.credentials.google_application_credentials), Rails.application.credentials.firebase_project_id ) NotificationSubscription.find_each(batch_size: 100) do |subscription| begin response = fcm.send_v1({ token: subscription.fcm_token, notification: { title: 'Un nouveau signal a été publié', body: 'Un nouveau signal a été publié, cliquez ici pour le voir' }, android: { priority: 'high' }, apns: { payload: { aps: { # alert: { # title: 'Un nouveau signal a été publié', # body: 'Un nouveau signal a été publié, cliquez ici pour le voir' # }, sound: 'default' } }, headers: { "apns-priority": "10", "apns-push-type": "alert" } } }) if response[:status_code] == 200 Rails.logger.info "Notification sent successfully to #{subscription.id} on device #{subscription.device}" else Rails.logger.error "Failed to send notification to #{subscription.id} body: #{response[:body]}" # subscription.destroy end rescue StandardError => e Rails.logger.error "Error while sending notification to #{subscription.device}: #{e.message}" subscription.destroy end end end and the logs show that it's successful but i dont receive the notification. When I test from firebase console I receive the push notification on both ios and android capacitor apps. I also added this in the apple delegate: Messaging.messaging().apnsToken = deviceToken Messaging.messaging().token(completion: { (token, error) in if let error = error { NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error) } else if let token = token { NotificationCenter.default.post(name: .capacitorDidRegisterForRemoteNotifications, object: token) } }) } func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error) } I also tried using apns tokens and ther apnotic gem: console.log('APNs Token:', token.value) if (platform === 'ios') { sendSubscriptionToBackEnd({ apns_token: token.value, device: platform }).then(() => { displaySnackbar(`APNs token: ${token.value}`, 'success') }) } }) # Create the APNs connection outside the loop connection = Apnotic::Connection.new( auth_method: :token, cert_path: StringIO.new(Rails.application.credentials.apns_key_path), key_id: Rails.application.credentials.apn_key_id, team_id: Rails.application.credentials.apple_team_id ) NotificationSubscription.find_each(batch_size: 100) do |subscription| if subscription.device == 'ios' begin # Create the notification for the current device token notification = Apnotic::Notification.new(subscription.apns_token) notification.alert = "Un nouveau signal a été publié" notification.topic = Rails.application.credentials.apple_bundle_id # Prepare and send the push push = connection.prepare_push(notification) push.on(:response) do |response| if response.ok? Rails.logger.info "Notification sent successfully to #{subscription.id} on device #{subscription.device}" else Rails.logger.error "Failed to send notification to #{subscription.id} body: #{response.status} - #{response.body}" end end connection.push_async(push) rescue StandardError => e Rails.logger.error "Error while sending notification to #{subscription.device}: #{e.message}" subscription.destroy end end end connection.join(timeout: 5) connection.close end but i have a bad token error: Failed to send notification to 223 body: 400 - {"reason"=>"BadDeviceToken"} I, [2025-01-23T02:23:59.013407 #104] INFO -- : [ActiveJob] [ApnsNotificationJob] I checked my aps entitlement env and its production, have all the certificates, keys.. so I dont understand why i can receive push notifications from firebase console but not from my app

Apple Push Notification service server certificate update
hi i'm testing the new certificate. I'm using the p12 certificate and without doing anything, the sandbox can still be functioned. I assume the new certificate has already been installed in the default path by linux. so I execute openssl s_client -connect 17.188.143.34:443 -servername api.sandbox.push.apple.com -verifyCAfile /etc/pki/tls/certs/ca-bundle.crt -showcerts and i received CONNECTED(00000003) depth=2 C = GB, ST = Greater Manchester, L = Salford, O = Comodo CA Limited, CN = AAA Certificate Services verify return:1 depth=1 CN = Apple Public Server RSA CA 12 - G1, O = Apple Inc., ST = California, C = US verify return:1 depth=0 C = US, ST = California, O = Apple Inc., CN = api.development.push.apple.com verify return:1 --- Certificate chain 0 s:/C=US/ST=California/O=Apple Inc./CN=api.development.push.apple.com i:/CN=Apple Public Server RSA CA 12 - G1/O=Apple Inc./ST=California/C=US -----BEGIN CERTIFICATE----- ... so the server indeed has the certificate, is this correct?

Live Activity without Dynamic Island
Is it possible to display a live activity on the lock-screen without a dynamic island? Or at least without expanding the dynamic island more than just for a small icon? struct SomeWidgetLiveActivity: Widget { var body: some WidgetConfiguration { ActivityConfiguration(for: SomeAttributes.self) { context in } dynamicIsland: { context in DynamicIsland { DynamicIslandExpandedRegion(.leading) { // Seems to be mandatory, any way around it? } } compactLeading: { } compactTrailing: { } minimal: { } } I couldn't quite find a way. Thank you

NotificationCenter observer method not being executed in some cases
I'm working with a deeplink I have to implement to my app. The deeplink is working because in some cases i will explain later the method is being executed. So when I tap the deeplink with a deeplink-tester-web I detect if the url is which I want and, if it's the case, i post a notification to NotificationCenter with a string parameter I need. Case 1. I tap the deeplink when the view controller with the addObserver method is at the background with the app itself. It works (the only case) Case 2. The app is closed so the deeplink opens the app directly in that view controller (the method is no being called event if the notification is there) Why? Case 3. The app is at the background but in another screen. When I tap the deeplink and, after returning to the app, travel to my viewController the method is not called when the ViewController becomes visible. Why? I've not seen anything in the documentation that can help me and i cannot access to the array of observers because the API does not allow that Thanks. Any help will be appreciate. Code: When the deeplink is tapped the app delegate method that manages universal links call to this code when the url is a specific one @objc func handleRecommendedOffer(offerId: String) { NotificationCenter.default.post(name: .deeplinkRecommendedOfferNotification, object: nil, userInfo: ["offerId": offerId]) } In my viewcontroller viewDidLoad (i've tried also viewWillAppear too): NotificationCenter.default.addObserver(self, selector: #selector(goToDetail(notification:)), name: .deeplinkRecommendedOfferNotification, object: nil) @objc private func goToDetail(notification: Notification) { if let userInfo = notification.userInfo, let offerId = userInfo["offerId"] as? String { showLoading() getOfferViewModel.getOfferDetail(id: offerId) } }

How to Retrieve Current Badge Count After applicationIconBadgeNumber Deprecation?
Hi Everyone, I noticed that applicationIconBadgeNumber has been deprecated in iOS17. While there's a new method to set the badge number using setBadgeCount(_:withCompletionHandler:), I couldn't find a way to retrieve the current value. Previously we used to call UIApplication.shared.applicationIconBadgeNumber, to get the current value, which is deprecated now. Does anyone know how to get the current badge count? Thanks!

Apple Push Notification service server certificate
Do we need this new certificate "SHA-2 Root : USERTrust RSA Certification Authority certificate" if we are using token based authentication with APNs? We are signing the JWT with the private Auth key? Or is the new certificate needed on top of this? We are doing something like this: Dictionary<string, object> payload = new Dictionary<string, object>() { { "iss", teamId }, // Apple Developer Team ID { "iat", unixTimestamp } // Issued-at time }; Dictionary<string, object> header = new Dictionary<string, object>() { { "alg", "ES256" }, { "kid", keyId } // Key ID from Apple Developer portal }; string token = JWT.Encode(payload, privateKey, JwsAlgorithm.ES256, header);

HOW TO: make sure that both old and new server certificates are included in the Trust Store
We are struggling with the lack of information provided by Apple re: Apple Push Notification service server certificate update We want help from other developers on HOW TO: make sure that both old and new server certificates are included in the Trust Store Exactly HOW is this done? What is the Trust store and how is it accessed? Is this done for our account once OR for each for the apps utilising APNs? Can anyone assist? Thanks Louise
