Experiencing Duplicate Notifications Issue Recently
For a period of time, we have frequently received reports of users receiving duplicate message notifications. We can ensure that the message is only sent once and there is only one ApnsId, but when it reaches the device, there are multiple duplicate notifications (2-3) I suspect this may be related to iOS 17, as there seems to be some overlap in time. Have others encountered similar problems? We sincerely hope to receive help from society. Thank you for your help~

Cloud Kit Push Notifications User Opened Notification Metric
I am checking the Push Notification Console of Cloudkit to understand my apps push delivery metrics. There are nice metrics in there to see push sends and discards. But I couldn't see any metric to understand "How many of the users opened the notiifications I send". Is there any way me to understand this statistic? Also can we export this metrics without logging in to CloudKit like an API request?

Apple Push Notification Issue: Having Trouble Decrypting Messages
I have multiple mobile applications, one developed in React Native and the other in Objective-C and Swift hybrid technology. I use my own system to send push notifications, and these notifications are left encrypted in the Apple queues. However, in any of my applications, I am unable to catch these messages in the code block where I decrypt them. As a result, users see the messages encrypted. While I can deterministically detect this issue on devices experiencing the offload feature from Apple, I've also noticed sporadic occurrences of this issue on devices not utilizing offload. Due to my security policies, I have no chance of sending messages unencrypted. I'm trying to understand why this is happening and need suggestions for a solution. Is there anyone who can help? Additional Information: I use my own system for push notifications. Messages are left encrypted in the Apple queues. I am unable to catch the messages in the code block where I decrypt them in one of the applications. I can deterministically detect the issue on devices experiencing the offload feature. I've noticed sporadic occurrences of this issue on devices not using offload. Due to security policies, I have no chance of sending messages unencrypted. I tried sending without offloading, and the messages arrived unencrypted I searched for a callback handler function on the Apple side - couldn't find one. To ensure notifications were sent correctly, I performed token checks in my database.

Unable to remove notification number in badge when enter app
Hi! I have recently added the functionality of notifications in my app. I can send notifications and I see them in my phone well. The problem is that even if I have no notifications, the badge shows I have 3 and I can not remove this notification when I read the notifications. What it is strange is that even if I send new notifications, the number 3 is still there...

getting push notifications delivered to iPhone simulator when CloudKit changes
I have a shopping list app that shares a list of Product records between users. The app on my phone shared its private database with another user account (running on a simulator) which accepted it. Both devices can see changes from the other if the device does a full refresh from iCloud. Now I want to have the app on the devices be notified when the other changes/adds/deletes a Product record. I did the following to get push notifications to work (but haven't been successful yet) I have enabled background fetch and remote notifications in my app capabilities. The app registers for remote notifications with UIApplication.shared.registerForRemoteNotifications() and receives the didRegisterForRemoteNotificationsWithDeviceToken callback. The app sets a subscription with CKModifySubscriptionsOperation for the "Product" recordType. I set the QoS to .utility on the appropriate private or shared database. However, when I add a Product record on my record, the didReceiveRemoteNotification callback doesn't execute. What am I missing?

How to send Push without sound and indication on iOS
Hi, I need a feature in the iOS app that requires updating the user screen via FCM. In other words, I have to update it with no sound and screen display, but this doesn't work. When I remove the notification field, the notification will not be displayed to the user, but the sound will be played. If I remove the sound field, I can make no sound, but the user will be notified. If I remove both, I'm not getting this from the iOS app. How can I solve this?? Which option should I send Push from the server?? I'm also using Notification Service Extension.

Help migrating from .p12 to .p8
Prior to .p8 tokens, we were using .p12 cert for communication with APNS. We have since migrated to use .p8 token within our 3rd party push notification provider however, we still have the .p12 cert associated with our AppStore provisioning profile. Do we still need to maintain the .p12 cert to ensure the validity of the AppStore provisioning profile? Will revoking the .p12 cert result in inability for Apple to recognize that the app has push notifications enabled?

FCM integration in flutter for both android and iOS working fine but in IOS version 17 and higher have issue with receiving notifications.
In Flutter application, Is there FCM related any changes for new iOS versions? I didn't find any solution regarding this. Working fine in android all versions and in iOS working fine till version 16. Also verified from app setting (version 17 and above), Notification permissions enabled. Also get success from this API - https://fcm.googleapis.com/fcm/send response - "multicast_id": 912044660XXXXXX, "success": 1, "failure": 0, But not receiving any message, tried with debug and console log but there is no message/log or error message.

window.safari.pushNotification.requestPermission() no longer works with Safari 17.3 on macOS 14.3
One Line Summary window.safari.pushNotification.requestPermission() is no longer showing a prompt to the user with Safari 17.3 on macOS 14.3 and it's callback fires as "denied". Why this is is important to fix Starting with Safari 16 for macOS 13 Apple introduced support for the standard Push API. However it is expected that the original Safari JS API window.safari.pushNotification should continue working, as many sites have not fully upgraded to the new API and Apple has not announced a deprecation. Environments NOT Working macOS 14.3 with Safari Version 17.3 (19617.2.4.11.8) macOS 14.4 Beta (23E5191e) with Safari Version 17.4 (19618.1.13.11.5) Working macOS 13.6.4 with Safari Version 17.3 (18617.2.4.11.11, 18617) MRE (minimal reproducible example) See the following site to quickly reproduce the issue noted here: https://public-mre-macos-window-safari-prompt-bug.glitch.me/

Force Update required after App Transfer for Push Notifications?
This question is a follow-on and clarification from this earlier post. I'd just like to confirm that after an App Transfer has been completed, whether there is any need for a new release to be cut? Judging from the prior post, my understanding is that a new release would not be necessary, and that all the existing versions of the app will continue to connect successfully with the APN servers. The only necessary update would be the server connection between the APN servers and the server used to generate notifications, with a new token or certificate. Is my understanding correct?

UNNotificationServiceExtension suddenly stopped working
Hi, I have a UNNotificationServiceExtension, which was running perfectly fine for more than a year. Last week, it has suddenly stopped working, with no apparent changes to the server-side application sending the notification to APNS. The strange part is that it works on some devices and it doesn't work on others. I have confirmed that notifications are enabled for the app in iOS system preferences. com.company.product is the bundle identifier of the main app com.company.product.yyyyy is the bundle identifies of the NSE appname.app and nse.appex are the placeholders for the name of the app and name of the NSE respectively Following is the NSE info.plist: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDisplayName</key> <string>yyyy</string> <key>CFBundleName</key> <string>yyyy</string> <key>CFBundleIdentifier</key> <string>com.company.product.yyyy</string> <key>CFBundleDevelopmentRegion</key> <string>en</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundlePackageType</key> <string>XPC!</string> <key>CFBundleShortVersionString</key> <string>y.y.y</string> <key>MinimumOSVersion</key> <string>13.0</string> <key>NSExtension</key> <dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.usernotifications.service</string> <key>NSExtensionPrincipalClass</key> <string>NotificationService</string> </dict> <key>CFBundleVersion</key> <string>yyy</string> </dict> </plist> Model: iPhone 15 Pro Max iOS Version: 17.3

iOS intermittently fails to send URLs via UISceneDelegate
I'm observing a sporadic bug in our web client where incoming URLs (triggered by a Push Notification or link tapped in another app) do not trigger either of the two expected API callbacks noted in the developer documentation for UISceneDelegate. Specifically, Apple's docs say: If your app has opted into Scenes, and your app isn’t running, the system delivers the URL to the scene(_:willConnectTo:options:) delegate method after launch, and to scene(_:openURLContexts:) when your app opens a URL while running or suspended in memory. Our client app has opted into scenes and the two callbacks mentioned above work reliably most of the time for incoming URLs. However, using the exact same test links or push notifications, I'm able to reproduce intermittent issues where I can see that neither of the above callbacks are triggered when the app is foregrounded to handle a URL. The bug seems to occur when: The app has been previously launched, and is backgrounded It's left in the background for some time (system memory pressure, from using other apps etc., might possibly play a factor also) In this scenario, sometimes when either an external link or URL via push notification is opened, I can see that neither of the two iOS delegate methods for UISceneDelegate are called. Our app is brought to the foreground correctly as though the URL will be handled, but the URL/link is not processed since it is never sent to our client. A few other notes: When the bug is repro'd using push notifications, I can see that our app receives a callback to userNotificationCenter:didReceive:, so the push notification definitely arrives. However, as noted above, the normal 2 API callbacks for UISceneDelegate are never triggered, and since those two callsites are where we handle incoming URLs, the URL from the push notification is never opened I haven't been able to observe any code in our app that precedes these hooks in our scene delegate that could be interfering. (As mentioned above, the same steps to replicate work the majority of the time) Does anyone know whether this could be a possible iOS bug? Any help/suggestions are greatly appreciated. Thank you

TARGET_OS_IPHONE/TARGET_OS_IOS not defined in iPhone SDK 17.x
In my app code I used TARGET_OS_IPHONE/TARGET_OS_IOS for SDK 15 and 16. After go on SDK 17.x these macros are not defined. In my investigation, I found that in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/TargetConditionals.h __is_target_environment(macabi) return false hence the issue. Could you please verify and explain, if I do not understand / use correctly. Regards, Alexei
