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 received an update to the APN root certificate. Testing the connection using MDM.pem to the push environment returned the following error:BadCertificateEnvironment
ERROR
I’m using Appnotic from my server to send notifications for an emergency service, where it is critical that notifications are delivered immediately.
My payload looks like this:
"aps": {
"alert": "Test alert",
"sound": {
"critical": 1,
"name": "sound.wav",
"volume": 0.5
},
"content-available": 1,
"category": "alert"
},
"topic": "com.fireservicerota.FSR-Primary-Alerting",
"custom_payload": {
"id": "11",
"type": "alert",
"incident_id": 23434,
"incident_response_id": 2652343,
"expiration_time": "2024-06-06T16:59:05+01:00"
}
}
I already have the critical alert entitlement and background processing enabled. Everything seems fine when debugging, but I’m experiencing issues:
• Some notifications never arrive
• Around 60% of notifications arrive with noticeable delay
Since this is an emergency app, delivery speed is crucial. What could be causing this inconsistency?
I have an app that pairs with a wearable Bluetooth device that collects users' health data. My web backend sends two push notifications every hour to all app users—one at XX:05 and another at XX:15. The first notification instructs the app to download data from the paired wearable device, while the second prompts the app to upload the downloaded data to the backend server's database.
However, I’ve noticed that many push notifications are not processed by iOS apps, especially at night. Based on Apple's documentation, iOS prioritizes push notifications and may ignore lower-priority ones to conserve battery life.
Is there a way to increase the priority to ensure that more (or all) push notifications are processed?
Would integrating the HealthKit framework help? Currently, I use Firebase Cloud Messaging (FCM) to send push notifications. Additionally, my app falls under the Health & Fitness category. Would changing it to Medical increase priority? P.S. I understand that Apple requires certain certifications for an app to be classified as Medical.

When I turn the Ringtone and Alerts volume all the way up, I expect standard notifications to play at the loudest level the device allows. In theory, this should match the volume of a critical alert with its sound.volume set to 1.0 in payload.
However, I’ve noticed that non-critical notifications still play quieter than critical alerts under these conditions. Critical alerts with volume: 1.0 sound noticeably louder than standard notifications, even though the Ringtone and Alerts slider is already set to maximum. And I couldn't find a documentation for this behavior anywhere.
Is this expected behavior on iOS? And is there any way to make non-critical notifications play at the same maximum loudness as critical alerts?
Thanks in advance for any clarification.
Hello everyone,
Our team is currently developing a PTT (Push-to-Talk) application using the officially recommended PushToTalk framework. During development, we've encountered a point of confusion regarding the application's behavior after being force-quit by the user.
Based on our understanding of the PushToTalk framework documentation (https://developer.apple.com/documentation/pushtotalk/creating-a-push-to-talk-app/) and the PTChannelManager session restoration mechanism, when a user manually kills the app from the background (App Switcher), the current PTT session (the system session managed by PTChannelManager) should terminate. Subsequent pushtotalk type pushes sent via APNS, without an active session, appear to be silently discarded by the system and cannot wake the app for processing (similar to what Kevin Elliott DTS mentioned in https://developer.apple.com/forums/thread/760506 Point D). This seems to prevent reliable PTT message reception in our app after a user force quits.
However, we've observed that some popular PTT applications on the market (e.g., TenTen) appear to successfully receive and play PTT voice messages from friends even after the user has performed a force-quit action. This behavior seems inconsistent with our test results and understanding based on the standard framework, posing a challenge for us in providing similar reliability using standard methods.
This naturally leads us to wonder how this capability is achieved. We've reviewed developer forums and are aware of the historical existence of a PTT-specific com.apple.developer.pushkit.unrestricted-voip entitlement, which allowed PushKit usage for PTT without CallKit binding. While Apple DTS engineers have repeatedly stated this entitlement is being deprecated and urged migration to the PushToTalk framework (e.g., https://developer.apple.com/forums/thread/763289), we are curious if the observed "wake-after-force-quit" capability might be related to some apps potentially still utilizing this outgoing special entitlement. Alternatively, is there perhaps a mechanism within the standard PushToTalk framework that allows wake-up after force quit that we haven't fully grasped?
Therefore, we'd like to ask fellow developers for clarification and discussion:
When using the standard PushToTalk framework, have others confirmed that the app indeed cannot be woken up by pushtotalk pushes after being force-quit by the user? Is this the expected behavior?
Has anyone successfully achieved a TenTen-like experience (reliable PTT reception after force quit) using only the standard PushToTalk framework? If so, could you share key implementation insights or areas to focus on? (e.g., Is it related to specific usage patterns of the restorationDelegate?)
How do you view this potential discrepancy between standard framework capabilities and the behavior exhibited by some apps? What considerations does this bring to development planning and user experience design (especially when users might have expectations set by the "always-on" behavior of other apps)?
Are there any best practices or specific techniques when using PTChannelManager session management and restoration that maximize PTT message reliability (especially after the app is terminated by the system in the background), while still adhering to the framework's design principles (like user awareness of the session via UI)? [For instance, another developer raised challenges related to PTT framework restrictions here: https://developer.apple.com/forums/thread/773981]
We hope this discussion can help clarify our understanding of the framework and gather community best practices for building reliable PTT functionality while adhering to Apple's guidelines.
Thanks for any insights or shared experiences!
I'm having trouble displaying the Apple Wallet pass logo on iOS 18 when a notification occurs. It works on iOS 17 but not on iOS 18 (tested on versions 18.1 and 18.3).
I ensured the Wallet pass icon sizes are correct:
icon.png → 29×29
icon@ 2x.png → 58×58
icon@ 3x.png → 87×87
Questions:
Has Apple changed any requirements for displaying Wallet pass logos in iOS 18?
Are there new size, format, or metadata constraints?
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!
I am developing a VoIP service.
Usually, when receiving a VoIP Push, Callkit is exposed immediately after receiving the message and the app is designed to be used.
However, there is an extremely intermittent phenomenon (not well reproduced) where the app does not wake up even when receiving a VoIP Push. And after a long time, the app wakes up and Callkit is activated. (A long time after receiving the call…)
Has anyone experienced the above phenomenon? I wonder if there are any reported parts depending on the OS version. (I have identified that it does not occur in the 17.x version, but it is difficult to guarantee because it occurs extremely intermittently)
The app is not running in the background, but... Could this be happening if there are a lot of pending operations in the background?
I need help urgently
Dear Apple Team,
I hope this message finds you well. I wanted to share a playful and innovative idea that could enhance the iPhone experience—particularly when viewing content in full-screen mode through apps like Apple TV or YouTube.
Feature Concept: Hands-Free Dismissal of Notifications
When the iPhone is in landscape mode, incoming notifications can interrupt the viewing experience. While Focus Mode and swipe gestures help, I thought of a more intuitive and hands-free interaction: using a light puff of air directed toward the screen to dismiss a notification.
This interaction could use the microphone or other onboard sensors to detect a brief burst of air, providing a fun and natural way to maintain immersion without touching the device.
If this isn’t feasible with current hardware, here are a few alternative concepts that align with the same goal:
Blink to Dismiss: Using Face ID sensors to detect a quick blink as a hands-free gesture.
Shake to Dismiss: A gentle shake gesture when holding the iPhone in one hand.
Gaze-Based Dismissal: Notifications automatically disappear after a brief moment of eye contact.
These ideas could offer both accessibility benefits and a touch of delight—making the iPhone feel even more magical and responsive.
Thank you for your time and for considering this suggestion!
Warm regards,
Badhan Baidya
The APNs Feedback Service domain “feedback.push.apple.com” was deprecated on March 31, 2021, and became unavailable after August 2025 due to domain name resolution failures.
Will this feedback service become available again in the future?
Also, is it possible to use the APNs Feedback Service with a domain different from “feedback.push.apple.com”?
PLATFORM AND VERSION: iOS
Development environment: Other: .net MAUI with vscode
Run-time configuration: iOS 18.1.1
DESCRIPTION OF PROBLEM
APNS notifications of apns-push-type pushtotalk sometimes stop arriving after switching networks.
STEPS TO REPRODUCE
We have created a simple app which can be used to deminstrate this issue. When you launch the app it displays the APNS token which you can then use fromn the Apple Push Console to manually send it PTT push notifications.
https://github.com/trampster/PttPushNotificationIssue
On an iPhone SE (we havn't been able to reproduce on our iPhone 11)
Start the APP to register for the APNS push notifications
Turn off the WiFi wait for 5 seconds
Attempt a push to the app manually using the Push Notifications Console (this should fail, which is fine)
Turn on Cellular and wait for it to connect
Attempt to push to the app manually using the Push Notifications Console
-> This fails, and all attempts to send an pushtotalk push notifications fail until the we switch network again.
Send a push while offline before connecting to the new network seems to make it happen more often but hard to tell for sure.
The results of the failed push in the console look like this:
Delivery LogLast updated: 30/01/25, 16:45:06 GMT+13 Refresh
30 Jan 2025, 16:45:03.661 GMT+13
received by APNS Server
30 Jan 2025, 16:45:03.662 GMT+13
discarded as device was offline
The device is actually very much online.
Switching networks again oftern makes things come right. But it doesn't seem to come right by itself.
We can't respond to network changes and do anything as the whole point of using push-to-talk push notifications is to wake up the app when in the background to answer a call, this means we are not running and therefore cannot respond to network changes to try to work arround this issue.
It seems our company server is sending to Apple push service the push notifications that are supposed to be transferred to devices our app is installed on – but you it seems you are blocking the request
We can see traffic going out from our server side towards the apple gateway notification server using port 2195 and we can see that the traffic gets "server-rst" meaning that the apple gateway server kills the connection
You might need to whitelist our external IP's
I've added a Notification Service Extension as a target to my React Native iOS app following Apple's official documentation. After completing all the setup steps as outlined in the documentation, the notification titles remain unchanged - notifications are arriving without any modifications, suggesting the extension isn't functioning properly.Testing Details:
Sending notifications via Apple Push Notification Console
Tested on iPhone 16 Pro Max (physical device)
Tested on iPhone 15 Pro simulator
Both show the same issue - no title modifications
The extension appears to not be executing at all.
Has anyone encountered similar issues with Notification Service Extensions in React Native projects, or can suggest troubleshooting steps to verify the extension is properly configured and running?
An Application Group with Identifier 'group.com.aaa.aaa.onesignal' is not available. Please enter a different string.
How can I Fix this error? I need to add it in this format.

The app will be wake up from killed status by silent notification or not?
This is a question for years, from my test. It will wake up.
Here the wake up means it will call the "didFinishLaunchingWithOptions" method. But we can not see the app in the "recent apps" list after switching home-screen up.
So any Apple dev can give me a detailed explain for this?
We would like to better understand the discrepancy between a Push To Start and the subsequent Updates where I see a number of recipients drop greatly.
Our assumption is that this is a result of the end user not clicking the "Allow" prompt when a push to start widget is shown on the screen for the first time, but we currently do not have a way to listen to the user's choice when prompted.
Is there any way of tapping into this, to determine if this is in fact where the variance is coming from, or if there is actually just a problem with the request to retrieve the update token from our end?
I invoked the getNotificationSettingsWithCompletionHandler method of UNUserNotificationCenter on multiple test devices. After dismissing the notification permission request dialog (without explicit denial), the returned UNNotificationSettings object showed inconsistent authorizationStatus values across OS versions:
**iOS 18: Returns UNAuthorizationStatusNotDetermined
iOS 14.2:** Returns UNAuthorizationStatusDenied
Where can I find official Apple documentation explaining this behavioral discrepancy between system versions?
Recently, I attempted to use LiveCommunicationKit to replace CallKit. The goal was to explore better features or integration.
However, a major problem emerged. When the app is in the background or killed, it shows no notifications. This seriously impairs the app's communication functionality as notifications are vital for users to notice incoming calls.
And it is working well when the app is in the foreground.
When the app is in the background, when the push message received. the app get crashed with the following information:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push.'
Also, when I use CallKit instead of LiveCommunicationKit, the app works well in all cases.
The code is here:
LCK wrapper:
class LCKWrapper : NSObject, ConversationManagerDelegate {
var mgr: ConversationManager
var lckDelegate: LCKDelegate
var currentCallId: UUID
@objc init(handler: LCKDelegate, appName: String, appIcon: UIImage) {
self.lckDelegate = handler
var iconData: Data?
iconData = appIcon.pngData();
var cfg: ConversationManager.Configuration
cfg = ConversationManager.Configuration(ringtoneName: "ringtone.m4a",
iconTemplateImageData: iconData,
maximumConversationGroups: 1,
maximumConversationsPerConversationGroup: 1,
includesConversationInRecents: false,
supportsVideo: false,
supportedHandleTypes: Set([Handle.Kind.phoneNumber]))
self.mgr = ConversationManager(configuration: cfg)
self.currentCallId = UUID()
super.init()
self.mgr.delegate = self
}
func reportIncomingCall(_ payload: [AnyHashable : Any], callerName: String) async {
do {
print("Prepare to report new incoming conversation")
self.currentCallId = UUID()
var update = Conversation.Update()
let removeNumber = Handle(type: .generic, value: callerName, displayName: callerName)
update.activeRemoteMembers = Set([removeNumber])
update.localMember = Handle(type: .generic, value: "", displayName: callerName);
update.capabilities = [ .playingTones ];
try await self.mgr.reportNewIncomingConversation(uuid: self.currentCallId, update: update)
print("report new incoming conversation Done")
} catch {
print("unknown error: \(error)")
}
}
}
And the PushKit wrapper:
@available(iOS 17.4, *)
@objc class PushKitWrapper : NSObject, PKPushRegistryDelegate {
var pushKitHandler: PuskKitDelegate
var lckHandler: LCKWrapper
@objc init(handler: PuskKitDelegate, lckWrapper: LCKWrapper) {
self.pushKitHandler = handler
self.lckHandler = lckWrapper
super.init()
let mainQueue = DispatchQueue.main
// Create a push registry object on the main queue
let voipRegistry = PKPushRegistry(queue: mainQueue)
// Set the registry's delegate to self
voipRegistry.delegate = self
// Set the push type to VoIP
voipRegistry.desiredPushTypes = [.voIP]
}
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) async {
if (type != .voIP) {
return;
}
await self.lckHandler.reportIncomingCall(payload.dictionaryPayload, callerName: "Tester")
}
}
