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

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.

i got some problem for the LiveAcitvity when i start it with notification.
The LiveActivity can not show,but it can work when i update or end a LiveActitvity;
And so,i think my configeration is right like the code;
thanks in advance
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.

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!

Hello Team,
We are currently experiencing an issue where some of our devices are not receiving push notifications. We are sending notifications via the Apple Push Notification portal (https://developer.apple.com/notifications/push-notifications-console/) using the following two requests. However, in both cases, the notifications are not being delivered to the devices.
Scenario 1 :
When we send a request with apns-push-type set to alert, we receive the following error.
Request :
curl -v
--header "authorization: bearer ${AUTHENTICATION_TOKEN}"
--header "apns-topic: com.testcompany.sampletest"
--header "apns-push-type: alert"
--header "apns-priority: 10"
--header "apns-expiration: 0"
--data '{"aps":{"alert":{"title":"Test Notification Title","subtitle":"Test Notification Sub Title","body":"Test Notification Body"}}}'
--http2 https://api.push.apple.com:443/3/device/*devicetoken*
Response:
{
"code": 400,
"message": "bad-request",
"reason": "The device token is inactive for the specified topic. There is no need to send further pushes to the same device token, unless your application retrieves the same device token.",
"requestUuid": "c4ae39b4-87e1-4269-a1e9-163f60ec0385"
}
Scenario 2 :
However, if we send the request with apns-push-type set to background, the request is processed successfully by APNs, but no notification is received on the device.
Request :
curl -v
--header "authorization: bearer ${AUTHENTICATION_TOKEN}"
--header "apns-topic: com.testcompany.sampletest"
--header "apns-push-type: background"
--header "apns-priority: 10"
--header "apns-expiration: 0"
--data '{"aps":{"alert":{"title":"Test Notification Title","subtitle":"Test Notification Sub Title","body":"Test Notification Body"}}}'
--http2 https://api.push.apple.com:443/3/device/*devicetoken*
Response:
Getting a message that The notification sent successfully but no notification is received on the device.
In both cases (with alert and background push types), the push notification does not reach the device.
Additionally, when we validated the device token using the APNs Device Token Validator, it appears to be valid and returns the following message.
"Device Token is valid for sending Alert & Background push-type notifications in the Production environment"
Affected Device:
macOS version : MacOS 15.3.1
Processor : Apple M1
Could you please assist me in resolving this issue?
Thanks
We operate a social network application, SportsYou with over 3 million monthly active users and are experiencing significant issues with push notification delivery through APNs.
We have a large number of users reporting they are not receiving push notifications. Our infrastructure uses AWS SNS integrated with APNs to deliver notifications. However, AWS CloudWatch consistently reports successful delivery (Success response), even though users confirm they never received the notifications.
Because we receive success responses from AWS SNS, our system does not attempt to recreate or refresh the device endpoints. This leaves us unable to detect or recover from these delivery failures automatically.
This issue is widespread and inconsistent. It affects users across multiple variables including different iOS versions, different device models, and different versions of our application. We cannot identify a clear pattern that would help us isolate the root cause.
With millions of active users, even a small percentage of delivery failures represents thousands of users experiencing a degraded service. This is significantly impacting user engagement and satisfaction.
We need guidance on how to properly diagnose this issue and ensure reliable notification delivery to our users. Specifically, we'd like to understand why we're receiving success responses when notifications aren't being delivered, and what steps we can take to detect and prevent these failures.
Hi,
My customer has acquired the assets of another company. We therefore need to transfer this company's app to my customer's account.
This app primarily functions using WebRTC video, which relies on APN PUSH notifications. I have reviewed the information about transferring an app from one developer account to another, particularly here: https://developer.apple.com/help/app-store-connect/transfer-an-app/overview-of-app-transfer. I understand that we need to generate a new SSL certificate that will be integrated into the app once it has been transferred.
Since users will not all update the app immediately, we will have two server certificates running in parallel for some time.
Is it allowed to send two notifications to the same iPhone, knowing that one of the two will systematically fail?
If not, what is the best practice for successfully migrating VOIP notifications?
Thank you in advance,
F. BABIN

In iOS 26, I can check the notification that arrives to the user when the AirPods or Apple Watch is fully charged. When tap the notification, notification only expands and does not include actions such as moving to an app.
I checked the documents of UserNotification and UNNotificationServiceExtension, but I couldn't find what I wanted.
I can expand by long-tapping as default, but I'm looking for a way to expand it without entering the app when I tap the notification.
I wonder if there is an API that I missed or if it's not publicly supported.
thank you for your support.
On December 6, 2024, I received the following email.
Does this mean that there is something that needs to be done on the app side or on the Firebase side?
Currently, in our project, we are using Firebase to set up push notifications.
If anyone knows how to deal with this or has taken any action, could you tell me what specific steps you took?
Action Required: Apple Push Notification Service Server Certificate Update
As we announced in October,
the Certification Authority (CA) for Apple Push Notification service (APNs) is changing.
APNs will update the server certificates in sandbox on January 20, 2025,
and in production on February 24, 2025. To continue using APNs without interruption,
you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root : USERTrust RSA Certification Authority certificate.
To ensure a smooth transition and avoid push notification delivery failures,
please make sure that both old and new server certificates are included in the Trust Store before the cut-off date for each of your application servers that connect to sandbox and production.
At this time, you don’t need to update the APNs SSL provider certificates issued to you by Apple.
Hello, I am trying to utilize the Critical Messaging API to allow my user to message 1 or multiple pre registered contacts automatically.
An issue I am having with this in testing is that when the application attempts to fire off texts to the phone numbers the success rate changes from trial to trial, with no variable changing. Sometimes I can send a Critical Message to multiple phone numbers in rapid succession, sometimes the message is only sent to 1 contact, and sometimes I get no successes. Each failure always returns the MSCriticalMessaging.notSupported error.
The API documentation states, "The send(_:to:) method only works if the app is backgrounded, if it’s called from foreground the framework returns a MSCriticalMessagingError.notSupported error."
If my app is always backgrounded in these tests, what other issues may cause this notSupported error return, and why does the outcomes success rate vary?
Hi all,
We’re implementing in-app subscriptions in our iOS app using App Store Server Notifications V2 in the production environment.
Everything is generally working well — we receive notifications such as DID_CHANGE_RENEWAL_STATUS, CANCELLATION, etc., and we log all incoming notifications into our own database.
However, we've encountered a single case where the INITIAL_BUY notification was not received for a specific user.
Interestingly, we did receive the later notifications (DID_CHANGE_RENEWAL_STATUS and CANCELLATION) for that same user.
Here is our setup:
App Store Server Notifications V2
Notification endpoint is stable and functioning normally (receives and logs other notifications)
Notifications are reliably stored in our database
The issue occurred only once for one user
Environment: Production
We've already contacted Apple Developer Support, but were informed that this issue is out of scope for direct support, and were directed to the Developer Forums.
Our questions:
Under what conditions might the INITIAL_BUY notification fail to be sent or delivered?
Is there any known behavior or scenario where Apple may skip the INITIAL_BUY notification?
Any recommendations on how to further investigate or verify whether it was sent from Apple’s side?
We’ve confirmed that the notification never hit our server (no logs, no DB record), and our system was healthy at the time.
Any insight would be greatly appreciated. Thank you!

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
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?
AlarmKit custom sounds are universally broken in iOS 26.0 stable - instead of playing your custom sound, it plays a system error/timeout beep.
I've spent days investigating why custom sounds result in what sounds like an error beep (like when you cancel an operation or hit a timeout) instead of the actual audio file. I can now prove this is an Apple bug, not implementation error.
Evidence:
Test 1: My Implementation
Followed Apple's documentation exactly
Tried both bundle and Library/Sounds (as documented)
Result: System error beep (not my audio)
Test 2: Professional Apps
Tested ADHDAlarms (popular AlarmKit example by jacobsapps) https://github.com/jacobsapps/ADHDAlarms
Their airhorn.mp3 custom sound: same error beep (not an airhorn)
Their default sound: works perfectly
Test 3: Device Testing
Physical iPhone (iOS 26.0 - 23A341): broken
iOS Simulator: broken
Not device-specific
Files are found correctly, but the actual audio file is never played. Instead, you hear what sounds like a system error/cancellation tone.
What I've Eliminated
Not a Library/Sounds vs Bundle issue (both broken)
Not a file format issue (.mp3, .caf, .m4a all broken)
Not an implementation issue (professional apps broken too)
Not a device issue (simulator and device both broken)
Not a file size issue (5KB to 2MB all broken)
The Documentation Lie:
Apple's docs for AlertConfiguration.AlertSound.named(_:) state:
"Choose a file that's in your app's main bundle or the Library/Sounds folder"
https://developer.apple.com/documentation/activitykit/alertconfiguration/alertsound/named(_:)
Both locations are broken.
Tested on: iOS 26.0 (23A341), Xcode 26.0.1, Swift 6.2
Impact:
This affects any app trying to:
Provide personalized wake-up sounds
Use custom alarm tones
Create meditation/sleep apps
Differentiate from default iOS alarms
Current Status:
Multiple bug reports filed: FB19900024, FB18237648, FB19779004
Apple engineer claimed "fixed in latest beta" in August
Still broken in iOS 26.0 stable (September)
Workaround:
None that I know of. You must use .default sound.
For apps needing custom audio, play it with AVAudioPlayer after the alarm fires and user opens the app.
Question:
Has ANYONE gotten custom AlarmKit sounds working in iOS 26.0 stable? If so, plzzz help I'd be so grateful.
Hi,
We received the following message.
Hello, We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate.
Note, that we are using Firebase to deliver push notifications and the connection is done via APN keys, not certificates.
Is there anything that we need to update in the application to mitigate the risk of not delivered push notes ?
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'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
