Back story: I'm developing an app that communicates with a personal medical device. We use critical alerts when we have hardware issues that could result in harm to the patient. The audio file is a 30 second file to make sure the patient is aware. If the app is open when they occur, we pop up a modal message in the app. When the user dismisses the notice, we call UNNotificationCenter::removeDeliveredNotifications(withIdentifiers:) to remove the critical alert and also to stop the audio file that is playing.
This normally works fine. However we discovered that if the patient leaves critical alert enabled but disables notifications for our app, that we can still post the critical alert and it goes off. However when the user dismisses the message, the removeDeliveredNotifications call does not work. I did some debugging and if call getDeliveredNotifications with this permission combination, it return 0 (normally it would return 1).
Does anyone know of another way to remove the critical alert in this situation? (or should I be submitting this as a bug?)

After updating to iOS 26 beta 1, I can't receive any push notifications from most applications.
I can receive notifications from like Calendar, which uses local & reserved notifications, but I can't receive any remote-based notifications.

Hi everyone!
I’m integrating push notifications for a taxi-driver app and ran into a blocking CarPlay issue.
When the iPhone is connected to CarPlay (wired or wireless), the push arrives on the phone without any sound and nothing is shown or announced on the CarPlay screen.
If I unplug CarPlay, the same push plays the default sound and shows a normal banner on the lock screen, so the payload itself looks valid.
Environment
iPhone 13 Pro, iOS 18.0
CarPlay head-unit: Xcode 16.2 CarPlay Simulator
App built with Flutter 3.22 + firebase_messaging: ^15.2.5
Deployment target: iOS 14.0
Xcode capabilities enabled: Push Notifications, Time-Sensitive Notifications
App settings on the device: Allow Notifications -› Sounds ON, Show in CarPlay ON
Siri › Announce Notifications › CarPlay: master toggle ON + my app added to the allowed list
Driving Focus = Off (same result if it’s On)
Native setup in AppDelegate.swift
UNUserNotificationCenter.current().requestAuthorization(
options: [.alert, .sound, .badge, .carPlay]
) { _,_ in }
let carPlayCategory = UNNotificationCategory(
identifier: "CARPLAY_ORDER",
actions: [],
intentIdentifiers: [],
options: [.allowInCarPlay]
)
UNUserNotificationCenter.current().setNotificationCategories([carPlayCategory])
UNUserNotificationCenter.current().delegate = self
application.registerForRemoteNotifications()
APNs payload that I send via FCM
{
"aps": {
"alert": {
"title": "New test order",
"body": "Location info test"
},
"sound": "default",
"category": "CARPLAY_ORDER",
"interruption-level": "time-sensitive",
"relevance-score": 1
}
}
What could be the problem? Please help me solve the error
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.
We're building a taxi driver app. Our goal is simple:
Play a notification sound when a new ride request arrives — even if the iPhone is connected to CarPlay.
We use Firebase push with "sound": "default" and "interruption-level": "time-sensitive". The app requests .carPlay and uses a category with .allowInCarPlay.
Everything works when CarPlay is disconnected — we get sound and banner. But when connected to CarPlay:
the push is delivered silently,
no sound is played (even on the phone),
Siri Announce is enabled, but nothing is spoken.
Questions:
Is notification sound blocked when CarPlay is active, unless the app has CarPlay entitlement?
Is Siri Announce the only way to notify the driver audibly in this case?
Would getting a CarPlay entitlement (e.g. CarPlay.communication) fix this without building a full CarPlay UI?
Thanks — all we need is a reliable sound alert when a new ride comes in.
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.
This error has been continuously occurring for about 9 hours. We have not replaced the certificate, modified the server code, or changed the firewall policy. Some requests succeed, but many are timing out, with several timeouts occurring every minute. We are unable to find the cause. Please help.

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
I am using UNCalendarNotificationTrigger and from my initial tests with simulator and timezone changes in my mac i see that notification donot get triggered at specific times if timezone changes, is this expected behaviour ?

Hi,
We recently updated our app icon, but the push notification icon has not been updated on some devices. It still shows the old icon on:
• iPhone 16 Pro — iOS 26
• iPhone 14 — iOS 26
• iPad Pro 11” (M4) — iOS 18.6.2
• iPhone 16 Plus — iOS 18.5
After restarting these devices, the push notification icon is refreshed and displays the new version correctly.
Could you advise how we can ensure the push notification icon updates properly on all affected devices without requiring users to restart?
Thank you.

We are observing an issue where the iOS Notification Service Extension (NSE) is terminated by the system during startup, before either didReceive(_:withContentHandler:) or serviceExtensionTimeWillExpire(_:) is invoked. When this occurs, the notification is delivered without modification (for example, an encrypted payload is shown to the user). System logs frequently contain the message “Extension will be killed because it used its runtime in starting up”.
During testing, we observed that CPU-intensive operations or heavy initialization performed early in the extension lifecycle — especially inside init() or directly on the main thread in didReceive often cause the system to kill the NSE almost immediately. These terminations happen significantly earlier than the commonly observed ~30-second execution window where the OS normally invokes serviceExtensionTimeWillExpire(_:) before ending the extension. When these early terminations occur, there is no call to the expiry handler, and the process appears to be forcefully shut down.
Moving the same operations to a background thread changes the behavior: the extension eventually expires around the usual 30-second window, after which the OS calls serviceExtensionTimeWillExpire(_:).
We also observed that memory usage plays a role in early termination. During tests involving large memory allocations, the system consistently killed the extension
once memory consumption exceeded a certain threshold (in our measurements, this occurred around 150–180 MB). Again, unlike normal time-based expiration, the system did not call the expiry handler and no crash report was produced.
Since Apple’s documentation does not specify concrete CPU, memory, or startup-cost constraints for Notification Service Extensions or any other extensions beyond the general execution limit, we are seeking clarification and best-practice guidance on expected behaviors, particularly around initialization cost and the differences between startup termination.
NSE Setup:
class NotificationService: UNNotificationServiceExtension {
static var notificationContentHandler: ((UNNotificationContent) -> Void)?
static var notificationContent: UNMutableNotificationContent?
static var shoudLoop = true
override func didReceive(_ request: UNNotificationRequest,
withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
NotificationService.notificationContentHandler = contentHandler
NotificationService.notificationContent =
request.content.mutableCopy() as? UNMutableNotificationContent
NotificationService.notificationContent!.title = "Weekly meeting"
NotificationService.notificationContent!.body = "Updated inside didReceive"
// Failing scenarios
}
override func serviceExtensionTimeWillExpire() {
NotificationService.shoudLoop = false
guard let handler = NotificationService.notificationContentHandler,
let content = NotificationService.notificationContent else { return }
content.body = "Updated inside serviceExtensionTimeWillExpire()"
handler(content)
}
}
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.
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 all,
We encountered an issue where APNs (Apple Push Notification service) push messages cannot be received during development. The specific description is as follows:
Our app runs on an iPad that connects to the cellular network using a SIM card and accesses the Internet through the company's MDM, which provides APN setting proxies.
During operation, we found that the device fails to receive push messages from APNs. Network packet capture revealed that the connection attempt by apsd to port 5223 failed. According to Apple's documentation (https://support.apple.com/zh-cn/102266), when port 5223 cannot be connected to, it will fall back to port 443 and use a proxy. However, our packet capture showed that when port 5223 was unreachable, the apsd service on the iPad did not attempt to establish a connection to port 443.
Since the iPad device currently cannot establish a connection with APNs, it consistently fails to receive push messages from APNs. We tried disconnecting the SIM card and using a Wi-Fi environment, and in this case, the iPad device was able to receive push messages from APNs normally.
Could you advise us on how to proceed with troubleshooting in this situation?

Hi team,
We've observed that for all background notifications (where content-available set to true, https://developer.apple.com/documentation/usernotifications/pushing-background-updates-to-your-app#Create-a-background-notification),
we never received any response with error string "Unregistered". This
differs from non-background pushes, where expired tokens are regularly
cleared.
Is this the expected behavior (i.e.,
background notifications will not return an "Unregistered" error), or could this indicate an issue on our side?
Thanks in advance for any clarification.
以下の問題が発生しています:
特定のデバイスでプッシュ通知が受信されません。
考えられる原因は何でしょうか?
プッシュ通知は自社のサーバーから送信しており、APNs(Apple Push Notification service)からは正常な応答が返ってきています。
ユーザーはデバイスで通知が有効になっていることを確認しており、ネットワークの問題も報告されていません。
この問題は複数のユーザーに発生しています。
I dont want my server to be spammed. Currently I am only in payment-related notifs (eg: user successfully renewed his subscription, user didnt successfully renew his subscriptions, ..)
Where can I set that?

Hi Apple Support team,
I would like to inform you that we were receiving push notifications to all regions. Recently we were facing push notifications are not receiving to brazil region. For all other regions we are receiving. We are using same APSN certificate. Any region specific permissions do we need to add. Please let me know. Thanks.
My App supports two services that is Push Notification for Alerts and a Voip Call feature whose notification also comes in the same way as of PushNotification but video rendering is done with GoogleWebRTC.
The App was working perfectly fine but from past few months these services are not working.[ Nothing is changed in App and on the server side to push the notifications]
Issues:
VoIP (Video call) not working: I have apns certificate which is valid in today's date and stays with the backend Server. My server sends the payload notification to APNS but on iPhone am unable to receive it. I have checked the App registration part also and is able to receive the token for the same.
Framework used are: PushKit, UserNotifications, GoogleWebRTC .
I don't understand where is the gap, the backend triggers the APNS but there no response.
Ports enabled on server are: 443, 5223, 2197, 2195, 2196.
Similarly Push notification were also not working, So I tried to change it to register on Firebase for device registration token And did some coding at backend to send the notification to that device. It was working perfectly fine from last few weeks, but it suddenly stopped. I checked the JSON Payload and tried to send it through PostMan, in both it says 200 Success. And in Application end am waiting for breakpoint to hit in userNotificationCenter(_: , willPresent, completionHandler).
What all I have checked:
1)My server to APNS server connectivity.
2)Verified the apns certificate. The certificate was created in October 2024, whose expiry is in Nov 2025 and it support both Sandbox and Production environment.
3)Checked required delegates are implemented in App. With the capability enable in it, is also sending registration token to backend.
Kindly guide me where I can check in this flow.
Thanks in Advance!
I'm running into an issue during the iOS build process for my app, and I'm hoping someone can point me in the right direction.
❗ The Problem
When attempting to archive the app via EAS Build (Expo), the build fails with the following error:
`Provisioning profile "HCF_AppStore_ProvisioningProfile" doesn't include the com.apple.developer.push-notifications entitlement. Profile qualification is using entitlement definitions that may be out of date. Connect to network to update.`
What I’ve Already Done:
Enabled Push Notifications capability for the App ID (com.rsmco.helpcreatefamilies) in the Apple Developer portal.
Deleted and regenerated the App Store Provisioning Profile after enabling the capability.
Confirmed the new profile is associated with the correct App ID and Distribution Certificate.
Uploaded the new profile to EAS (Expo) and rebuilt the app.
Yet the error persists during the Xcode archive step with Exit code 65.
