UNNotificationAttachment convenience init method seems to be checking for supported file types based on the extension of the file URL provided as a constructor parameter. This seems to be sub-optimal at best and incorrect at worst.
Is this is a known issue for which a bug already exists?

I have a “1” above the setting app on my iPhone. However when I open settings there is no notification that shows up. I have tried force restarting and done the beta updates as they release however nothing works to got rid of it. What can I do?

I have multiple app ids that are registered with Push Notification, however they do not hsow up in the Push Notification Console for testing.
I’m currently developing an iOS app built in Unity, exported to Xcode for signing and deployment. The app needs to register for Apple Push Notifications (APNs) to retrieve the device token and register it with a backend service (PlayFab).
Despite enabling the required capabilities and entitlements, the app never receives a device token — the authorization request succeeds, but the token remains empty (req.DeviceToken is null in Unity).
I’ve confirmed that the issue occurs before PlayFab or Firebase are involved, meaning the app never receives the token from Apple Push Notification service (APNs) itself.
The Unity script I am using is:
#if UNITY_IOS
using UnityEngine;
using Unity.Notifications.iOS;
using PlayFab;
using PlayFab.ClientModels;
using System.Collections;
using System;
public class iOSPushInit : MonoBehaviour
{
private const int MaxRetries = 5;
private const float RetryDelay = 2f; // seconds
void Start()
{
Debug.Log("🛠 iOSPushInitDebug starting...");
StartCoroutine(RequestAuthorizationAndRegister());
}
private IEnumerator RequestAuthorizationAndRegister()
{
// Request Alert + Badge + Sound permissions and register for remote notifications
var authOptions = AuthorizationOption.Alert | AuthorizationOption.Badge | AuthorizationOption.Sound;
using (var req = new AuthorizationRequest(authOptions, true))
{
Debug.Log("⏳ Waiting for user authorization...");
while (!req.IsFinished)
{
yield return null;
}
Debug.Log($"🔔 Authorization finished at {DateTime.Now}: granted={req.Granted}, error={req.Error}");
if (!req.Granted)
{
Debug.LogError("❌ User denied notification permissions! Cannot get APNs token.");
yield break;
}
// Authorization granted → check for device token
int attempt = 0;
string token = req.DeviceToken;
Debug.Log($"req.DeviceToken: {req.DeviceToken}");
while (string.IsNullOrEmpty(token) && attempt < MaxRetries)
{
attempt++;
Debug.Log($"ℹ️ APNs token not available yet. Attempt {attempt}/{MaxRetries}. Waiting {RetryDelay} seconds...");
yield return new WaitForSeconds(RetryDelay);
token = req.DeviceToken;
}
if (string.IsNullOrEmpty(token))
{
Debug.LogWarning("⚠️ APNs token still null after multiple attempts. Try again on next app launch.");
yield break;
}
Debug.Log($"📱 APNs Token acquired at {DateTime.Now}: {token}");
// Register with PlayFab
var request = new RegisterForIOSPushNotificationRequest
{
DeviceToken = token,
SendPushNotificationConfirmation = false
};
PlayFabClientAPI.RegisterForIOSPushNotification(request,
result => Debug.Log("✅ APNs token successfully registered with PlayFab."),
error => Debug.LogError("❌ Failed to register APNs token with PlayFab: " + error.GenerateErrorReport()));
}
}
}
#endif
When running on a real device (not simulator), the following is logged in Xcode:
🔔 Authorization finished: granted=True, error=
ℹ️ APNs token not yet available. Try again on next app launch.
In the Xcode console, I do not see the expected APNs registration message:
[Device] Registered for remote notifications with token: <...>
Environment Details:
Engine: Unity 6000.2.6f2
Notifications package: com.unity.mobile.notifications 2.4.2
Xcode: 16.4 (16F6)
iOS Device: iPhone 12, iOS 26.0.1
Testing Method: Building directly from Unity → Xcode → real device
Signing mode: Automatic (with correct Team selected)
Certificates in account:
Apple Development certificate (active)
Apple Distribution certificate (active)
Provisioning Profile:
Type: App Store (also tested Development profile)
Enabled Capabilities: Push Notifications, In-App Purchase
App ID Capabilities:
Push Notifications: Enabled
Development SSL certificate: Present
Production SSL certificate: Not generated (yet)
Background Modes -> remote notifications
What I Have Verified:
✅ Push Notifications capability is enabled in the Xcode target (not UnityFramework).
✅ Team and Bundle Identifier match my Apple Developer App ID.
✅ App ID has Push Notifications enabled in the Developer Portal.
✅ Tested on a real iOS device with working internet.
✅ Rebuilt and reinstalled app after enabling Push Notifications.
✅ Authorization dialog appears and permission is granted by user.
How can I resolve this issue?

Hello Everyone,
I somehow missed to renew the APNS Certificate,
I am new to Apple Ecosystem, I can not see the expired or any Certificates under
Certificates, Identifiers & Profiles
Can anyone help me with this!
I’m receiving notifications from all third-party apps that I use however, most of the time there is no sound or haptics with the notification. In some cases, very seldomly I will receive a sound when a notification comes in, but that’s only with one of the many third-party apps that I use. I’ve spoken to Apple about this when this whole problem started during an update that you guys rolled out sometime between September and November 2024. They blamed it on the app programmers but I think at this point we all know that it’s Apple’s inability to accept that the problem is on their end. I never had problems receiving notifications from any of the apps prior to that.
I guess my question is will Apple ever fix this or are they going to sweep it under the rug and pretend like it doesn’t exist?
We are so interested in AlarmKit which is presented at WWDC25. While we planning our app using AlarmKit, We had a few questions come to mind and were hoping you could provide some clarity. Please excuse the rather long list of questions, as we don't currently have a device available to test these features ourselves.
System Actions Related
Is there a limit to the number of alarms that can be scheduled using AlarmKit?
Are alarms scheduled with AlarmKit persistent across device reboots?
When an alarm is dismissed (either by swiping or pressing the power button), can our app detect this action and execute code in response?
Can we control the behavior of the physical Lock Screen buttons when an AlarmKit alarm is active, for instance, to trigger a snooze action?
Does AlarmKit function correctly during Do Not Disturb or Low Power Mode?
What is the expected behavior when an alarm from our app (using AlarmKit) overlaps with an alarm from another app that also uses AlarmKit? Which one is going to get its priority?
Thank you for your help.
Sincerely

Is there a way to configure the APNS notification sound volume to be louder?
I am implementing some custom sounds(narrative sentences) for APNS, it does play the custom sound, but the volume of the custom sound is not loud enough even though I had set the device's volume and "RingTone and Alerts" volume to max.
I tried to amplify the custom sound file, it does play louder but the result is minimum if I want to maintain the quality of the sound without it been distorted.
I tried to use Notification Service Extension, AVAudioPlayer and AVAudioSession to play the sound, it does play louder in max volume compare with relying on default sound payload in APNS, but the problem is AVAudioPlayer and AVAudioSession do not seems to be usable when the application is in background or killed state, is there any other alternative I could use?
I have used the Push Notifications Console and verify that the test notification reaches my device (it says "not necessarily the app"). However, GameCenter notifications are not reaching the app. When one device passes the turn, the turn is successfully passed as seen in the Matchmaker VC. However, the app does not get the turn pass notification whether or not it is running. No banner appears if the app is not running (but it does when using the Push Notifications Console).
Please advise.

Hi All,
im working on a project to send a push notification in CarPlay.
Current accepted by apple entitlements is driving.
Are custom actions / buttons allowed/supported in CarPlay notifications?

Is there any information for developer about notification forwarding which is published in iOS 26.3? how to use it ?
When performing the P12 certificate sending test, there was an error stating that authentication failed due to the remote party closing the transport stream. May I ask how to solve this?
Currently, I have implemented local cache update with server data when app is killed using Push Notification and Notification Service Extension. So it works even the app is killed by the user, but I wanted to know whether this is app review safe work around or not as I am not finding any documentation for this.
I'm observing that when a silent push notification is sent to our app, is is started up in the background for 30 seconds before being suspended until the app is launched by the user. This causes data to persist from the silent push notification to the user app launch.
I couldn't find documentation on this behavior for silent push notifications, and was wondering if it's possible to have the app terminate after handling the silent push notification. Is there documentation on the general flow of silent push notifications as well?
I'm able to handle the edge cases if the app has to be suspended until user launch, but just want to confirm that this is the expected behavior before I go about handling it this way.
There's a list of bug reports:
FB19778882
FB19813796
FB19852724
FB19767262

Me and many other users have issue with push notifications. To reproduce this you should do this steps:
Lock iPhone and make it idle for 10+ minutes;
Send any message from other device via third-party app that uses push notifications (WhatsApp, Telegram and etc.);
After few attempts you can see, that messages don't deliver. They delivers immediately when I unlock iPhone or go to the app.
This bug reproduces on iOS 18.7 and 27.
As I think iPhone goes to deep sleep after 10+ minutes after it locked and don't get push notifications. I've tried everything: many of settings, DFU without backup, but nothing helps to resolve this issue. Pay attention, please, cause this bug is very annoying and present on iOS 18.7 (that is the last for many devices) and latest iOS 26. Thanks!
Is there anyway that I could use AVAudioSession, AVAudioPlayer or anything similar in Notification Service Extension?
I am trying to implement Audio Playback in the Notification Service Extension to play specific audio file when receiving Notification regardless the app state(foreground, background or killed), but I am not able to activate audio session in Notification Service Extension.
NSError *sessionError = nil;
BOOL success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&sessionError];
success = [[AVAudioSession sharedInstance] setActive:YES error:&sessionError];
if (!success) {
NSLog(@"Error activating audio session: %@", sessionError);
}
Below is the error that I got when I am trying to run the code above in Notification Service Extension.
Error Domain=NSOSStatusErrorDomain Code=561015905 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed}
I’m using iOS 26 beta 9 on my iPhone 15 Plus. When I receive a call from a contact with multiple phone numbers, the call history does not clearly show which specific number was used to call me. Why? How to fix this issue?

Hi Team,
We are building oru subscrption app and want to rely on server side purchase / subscription related notifications. We went through
https://developer.apple.com/documentation/appstoreservernotifications/enabling-app-store-server-notifications
We wanted to understand the reliability and latency for server side notifciations provided by Appstore.
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)
}
}
Hi there,
Thank you for the framework 🙏
if I use Alarm.Schedule.Relative with Alarm.Schedule.Relative.Time(hour: hour, minute: minute) and Alarm.Schedule.Relative.Recurrence.never it seems like there is some (odd?) limit where alarm will get scheduled to next day if too close?
For example, lets say the current time is 12:00 PM, if I schedule alarm for 12:02 PM, it will schedule it for next day, while if I do 12:05 PM it will work as expected.
Is that expected? If yes, what's the behavior and is that documented anywhere?
I would expect any alarm thats scheduled in the future to fire for the current day (maybe if it's only 1 minute it gets tricky).
One problem is also that even if the framework says an alarm is scheduled, I don't have access to the "next alarm date"? I wish I did as otherwise I have to compute it (by "guessing" the AlarmKit calculation) if I want to do anything with that date.
Honestly, sometimes I think I am just going crazy when the alarm doesn't fire, but there SEEMS to be some odd behavior around this?
(of course, feel free to correct me on anything - I could be missing documentation or not understanding something)
