when I implementation the UNUserNotificationCenterDelegate
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
var status = ""
if (UIApplication.shared.applicationState == .active) {
status = "active"
} else if (UIApplication.shared.applicationState == .background) {
status = "background"
} else if (UIApplication.shared.applicationState == .inactive) {
status = "inactive"
}
completionHandler()
}
I find that UIApplication.shared.applicationState == .background this case can not execute when application is in background。
why applicationState is inactive not background?

Hello. I'm currently implementing Apple Notification v2 to prepare for refunds for in-app purchases, but I'm not receiving requests from Apple servers to my backend server.
I've applied HTTPS (TLS 1.2) and correctly registered production/sandbox notification URLs on App Store Connect.
After requesting a test notification, when I check the status of testNotificationToken, I receive an UNSUCCESSFUL_HTTP_RESPONSE_CODE as follows:
{"signedPayload":"......":[{"atteptDate":1752128001970,"sendAttemptResult":"UNSUCCESSFUL_HTTP_RESPONSE_CODE"}]}
The endpoint for receiving notifications is set to accept POST requests with application/json format, and it responds with 200 (OK) without any content. However, Apple notifications are not coming through.
Could anyone help me with this issue?

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!
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 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.
Our application is designated to be used in a quite noisy environment (childcare facility) so we have implemented really annoying custom sounds. Unfortunately the system audio session playing custom sounds is apparently limited to half of the device volume possibility, even though the user sets full volume in the settings. How to change this behaviour to get louder notification sounds?
To be clear, I don't want to overcome user settings. If the user sets quieter volume or he sets the silent mode, the application should be silent too. I just need that 100% volume settings is actually 100% device volume.
This is a really critical feature for us and for our customers. We have already tried to ask for the critical alerts and we have been rejected.
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 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
requestUrl:https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/test

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
I created an app. One if its functionalities is receive Remote Notification in the background, while app is monitoring Significant Location Changes (SLC). This functionality worked fine. I was receiving these notifications correctly. Sometimes instantly, sometime with small or large delay.
And then I send the app for review. It was rejected with 3 remarks:
The app or metadata includes information about third-party platforms that may not be relevant for App Store users, who are focused on experiences offered by the app itself (I wrote that app communication works both for iOS and Android.)
The app declares support for audio in the UIBackgroundModes key in your Info.plist but we are unable to locate any features that require persistent audio.
EULA (End User License Agreement) is missing for in-app purchases.
After the rejection the app is no longer receiving these notifications. They are there, since the app receives them, when I open app, or significant location change is detected. It also works, when I run the app directly from Xcode (in debug mode), not from TestFlight nor in Sandbox.
It seem to me like Apple somehow spoiled my background capabilities on purpose or accidentally. Is it possible? What can I do with it? Is it the case that I should just fix the review remarks and send the app back to review, and once the app passes it, it will work again? Or should I not count on it? Any suggestions? I asked Apple using:
https://developer.apple.com/contact/topic/#!/topic/select
but so far no response.

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?

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 have integrated a Notification Service Extension in my app to handle rich push notifications with images. The issue occurs on iOS 15 and iOS 18 devices—while the text content of the notification shows, the image is not displayed. However, the rich push notification works fine on other iOS versions (e.g. iOS 16, iOS 17)
I’ve tried the following steps:
Verified App Groups are the same for both the main app and the extension.
Checked the "mutable-content" flag in the notification payload.
Added a print statement in the NotificationService.swift to check if it’s running. It doesn’t appear in the Xcode logs.
I’ve tried using Attach to Process in Xcode, but nothing happens.
The app is installed on a real device, and I’m testing with push notifications when the app is in the background.

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
Can I using AudioServicesPlaySystemSound for play sound os system on NotificationService?
Issue:
I am making an application that stores data locally from notifications fired from the server. Everything works fine in the foreground but the background is having problems with not being triggered when notifications are fired.
So we tried firing 2 notifications at the same time, including default and silent types. But the problem continues to arise on ios 18, when firing multiple times like that, the trigger is not handling all notifications, leading to data loss. I tried on ios 15 and it worked fine.
Environment:
Device or Simulator: Iphone 11 pro max (iOS 18.3.2
Steps to Reproduce:
Open app, allow received notification.
Move app to background mode or terminate app.
Sent 2 notifications:
a. Default notification payload:
{
"aps": {
"content-available": 1
},
”notification”: {…},
“alert”: {..},
“data": "some_value"
}
b. Silent notification payload:
{
"aps": {
"content-available": 1
},
”data": "some_value"
}
What I've Tried:
Trigger notification in function:
application(_:didReceiveRemoteNotification:fetchCompletionHandler:)
Handle write data to local storage in above function, put it in background thread also.
Thanks in advance!

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.
In the new AlarmKit API, how do you localize NSAlarmKitUsageDescription?
In the case of other usage descriptions, such as NSLocationWhenInUseUsageDescription, you can use an InfoPlist.xcstrings file, but this does not appear to work for NSAlarmKitUsageDescription.
