I've got an app with several app extensions (call extension, action extension, notification service extension, message filtering extension, notification content extension).
If I need to interactively debug these then I can select the scheme and run the extension within Xcode for all of them except for the notification content extension, with that I get an error dialog summary saying:
Failed to install the app on the device / The provided item to be installed is not of a type that CoreDevice recognizes.
Which when expanded has the blumpf posted below.
Why can I not run the notification content extension, when I can run any other type of app extension?
Failed to install the app on the device.

I have created a configuration profile which basically just turns off notifications for Shortcuts app but I am unable to install it on my iPhone as I am getting the following error “This profile can be installed on a supervised device only” can someone please help me with this? Would also appreciate if you have another way to turn off shortcuts notifications permanently since when I turn it off via screen time it keeps turning itself ON every couple of days.

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?
The system calendar when showing a calendar event shows a relative timestamp on the notification versus all other apps which have a timestamp of when the notification was sent.
Is there a way to set the timestamp to be relative? I am currently working on a calendar app and we should be able to use the same system that apple uses for its own calendar.
Post about this on stack overflow from someone else a few years ago
Hi Team,
We’re following up on our request for the Critical Alert entitlement for our app, which we plan to use to notify users about critical states of their devices. It’s been almost 4 weeks since we submitted the request, and we wanted to check on the typical review timeline so we can plan our upcoming work accordingly.
If there’s anything we can provide or clarify to help complete the review or make the process easier, we’d be happy to assist. or the right forum to reach out to.

Hello,
We are trying to implement Actionable Notifications on iOS via Remote Notifications.
According to Apple’s official documentation (Declaring Your Actionable Notification Types),
it is recommended to register notification categories at launch time.
However, in our use case, the number of buttons and their actions in the Actionable Notification are determined at the time of the Remote Notification request.
This means that we cannot predefine the categories at app launch but need to dynamically configure them based on the payload of the Remote Notification.
Our Approach
We are considering setting aps.mutable-content = 1 and using Notification Service Extension to modify the categoryIdentifier dynamically.
Below is the JSON payload we plan to use for Remote Notifications:
{
"aps": {
"alert": {
"title": "New Message Received!",
"body": "Check out the details."
},
"category": "DYNAMIC_CATEGORY",
"mutable-content": 1
},
"categoryData": {
"id": "DYNAMIC_CATEGORY",
"actions": [
{
"id": "REPLY_ACTION",
"title": "Reply",
"options": ["foreground"]
},
{
"id": "DELETE_ACTION",
"title": "Delete",
"options": ["destructive"]
}
]
}
}
Questions:
Can we dynamically configure Actionable Notifications based on the Remote Notification payload?
If we set categoryIdentifier in Notification Service Extension’s didReceive(_:withContentHandler:), will users still see the correct action buttons even if the app is terminated?
What is the recommended approach to dynamically configure Actionable Notifications at the time of receiving the Remote Notification, rather than at app launch?
I have an app available for download in the Apple App Store. The app sends local notifications, which are scheduled at the user's request once the app launches. I've recently learned that when new versions of my app are deployed and automatically update on the user's device, previously scheduled local notifications are deleted. Given my app design, the user can re-launch the app in order to re-schedule the local notifications. This is a bit of a problem, though, because part of my app's value is in reminding the user - so after requesting a local notification, the user expects to receive a local notification and then launch the app, not the other way around.
Given this, I've been exploring solutions so my app continues to function as expected (including delivering local notifications, even if the app hasn't yet been launched) after an app update. I've explored .backgroundTasks(), but they too are apparently deleted with an app update and require the app to be re-launched first to work as expected. Another solution might be to use push notifications instead of local notifications, but that seems like a very involved solution if I'm just looking to make sure that local notifications persist after an app update. I can't be the only person to have this dilemma - am I overlooking a simple solution?
@App Store Commerce Engineer hi, have you already implement something for handle server notification if user buy non consumable purchases product, how my server should know if user boutght something ?

We have a question regarding iOS app configuration and the Remote notifications background mode.
During our testing, we observed:
*When enabling or disabling Signing & Capabilities > Background Modes > Remote notifications, the change does not take effect on devices that already have the app installed.
*The app continues to behave according to the old configuration.
*Only after uninstalling the app and reinstalling it from the App Store do the new settings take effect (for example, whether the app can be woken up by silent push).
*We also tested updating the app with a new version number (App Store upgrade flow), but the new settings still did not apply.
Our questions are:
1.Is there any way to make iOS re-read the updated Signing & Capabilities (Background Modes) settings without requiring a full uninstall/reinstall?
2.Is it expected behavior that even an App Store upgrade with a new version number will not apply these changes?
thanks!

I'm trying to provide custom localized descriptions for the iOS notification permission popup in my app, which supports multiple locales. To achieve this, I'm using InfoPlist.strings files per locale with the following keys:
NSUserNotificationsUsageDescription
NSUserTrackingUsageDescription
The issue I'm facing is that NSUserTrackingUsageDescription is working correctly across all tested locales, but NSUserNotificationsUsageDescription only works for some locales.
Locales tested:
Working: ja, tr, fr-CA
Not working: fr-BE, nl-BE
In each case, the correct localized NSUserTrackingUsageDescription appears, but the NSUserNotificationsUsageDescription falls back to the default or does not appear as expected in fr-BE and nl-BE.
I'm using Xcode 16 and testing on both iOS 18 simulator and physical devices, and the issue is consistent across both.
Any insights on whether this is a known issue in iOS or if there are additional steps needed for NSUserNotificationsUsageDescription to localize properly would be greatly appreciated.
We are attempting to update our app to use the PTT framework, as it has been made clear that this will be required in a future iOS version as opposed to using the Unrestricted VoIP entitlement we are using for several features of our app.
However, the behavior of this framework poses some problems with implementing our app's functionality:
It is not possible to programmatically join a channel when the app is not in the foreground. This hinders our ability to implement the Automatically activate radio stream feature of our app, which allows users who have opted into this feature to immediately begin hearing live PTT audio from their agency following an incident alert. Having the app constantly "joined to a channel" and using the restoration delegate could potentially work, however this is not ideal as this would result in the PTT UI needing to be displayed at all times, even when no radio stream is activated.
We have a "Text to Speech" option that, when enabled, reads out the content of an incident alert after the alert sound has played. This currently happens by triggering an AVSpeechSynthesizer in the PushKit incoming push callback. It may be possible to render TTS audio on the fly in a Notification Service Extension and assign it as the notification's sound, if that is possible this is less of a problem.
We also use the PushKit callback to, again if the user has enabled it, activate a "Shake to Respond" feature, allowing a short period of time after receiving an incident alert in which the user can shake their device to indicate that they are responding to the incident. There does not appear to be any way to have the level of background execution required to implement this using an NSE, and this is of course beyond the scope of the PTT framework.
What options do we have to be able to continue to provide this functionality, without risk of it being disabled in a future iOS version?
When sending a single push notification to iOS 18 devices
users receive the same notification multiple times. This issue appears specific to iOS 18 and was not observed in previous iOS versions
Our server logs confirm each notification is sent only once. Notification payloads include proper apns-id values for identification and no network issues detected on our side
I have multiple app ids that are registered with Push Notification, however they do not hsow up in the Push Notification Console for testing.
In macOS, how can I use UnmutableNotificationContent notifications to prevent the main window from activating when clicking the notification?
code:
import Cocoa
import UserNotifications // Mandatory import for notification functionality
class ViewController: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Automatically request permissions and send a test notification when the view loads
sendLocalNotification()
}
/// Core method to send a local notification
func sendLocalNotification() {
let notificationCenter = UNUserNotificationCenter.current()
// 1. Request notification permissions (Mandatory step; user approval required)
notificationCenter.requestAuthorization(options: [.alert, .sound, .badge]) { [weak self] isGranted, error in
guard let self = self else { return }
// Handle permission request errors
if let error = error {
print("Permission request failed: \(error.localizedDescription)")
return
}
// Exit if user denies permission
if !isGranted {
print("User denied notification permissions; cannot send notifications")
return
}
// 2. Construct notification content using UNMutableNotificationContent
let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Swift Notification Test" // Notification title
notificationContent.subtitle = "macOS Local Notification" // Optional subtitle
notificationContent.body = "This is a notification created with UNMutableNotificationContent" // Main content
notificationContent.sound = .default // Optional notification sound (set to nil for no sound)
notificationContent.badge = 1 // Optional app icon badge (set to nil for no badge)
// 3. Set trigger condition (here: "trigger after 3 seconds"; can also use time/calendar triggers)
let notificationTrigger = UNTimeIntervalNotificationTrigger(
timeInterval: 3, // Delay in seconds
repeats: false // Whether to repeat (false = one-time only)
)
// 4. Create a notification request (requires a unique ID for later cancellation if needed)
let notificationRequest = UNNotificationRequest(
identifier: "SwiftMacNotification_001", // Unique identifier
content: notificationContent,
trigger: notificationTrigger
)
// 5. Add the request to the notification center and wait for triggering
notificationCenter.add(notificationRequest) { error in
if let error = error {
print("Notification delivery failed: \(error.localizedDescription)")
} else {
print("Notification added to queue; will trigger in 3 seconds")
}
}
}
}
}
Currently, our company server is using the push service by calling APNS through the p8 certificate.
In this process, our server does not have a CA certificate or SSL certificate in use.
Only the p8 certificate is installed and only performs the role of calling APNS.
If it is used like this, is there no need to update the CA certificate separately?
Or do I have to apply a new SSL certificate and add the CA to it?
Can someone help me plz?

We integrated App Store Server notification, to get notified about CONSUMPTION_REQUESTS and REFUND notifications.
In the data, we noticed same transactionId have multiple REFUND decisions, usually REFUND_DECLINED and then REFUND. Why is that? Did user contact customer support ?
For the second (or later) REFUND decision, CONSUMPTION_REQUEST notifications are usually not sent, but thats not always the case. Sometimes, REFUND decision are the same. Sometimes, we get even 3 or more REFUND related notifications for same transactionId, e.g:
2024-12-02: REFUND_DECLINED
2024-12-05: REFUND_DECLINED
2024-12-12: REFUND
Do user request refund again ? Do they contact customer support ? But I can not explain why sometimes status it REFUND at first, but then later REFUND_DECLINED.
Thank you already in advance:)

Hello, it seems like starting from iOS 18.0, it is possible to entirely skip the notifications permission request alert by swiping up from the bottom of the screen. It doesn't work this way with any other kinds of system alerts, nor in iOS 17.4 (tested it in the Simulator though).
So, is it a bug? Or is it intended? Either way, I haven't found any information regarding that.
The problem with that is when you skip the alert, notifications are missing from the app preferences.
We are trying to figure out a strange issue.
Our app has not changed for at least 10 months but my devices and the QA tester device have all stopped receiving push/call notifications for twilio voip
The twilio credential and apple voip services certificate are in date and valid
It is pointing to the correct bundle id and topic (not changed configuration for years)
token passed in to TwilioVoiceSDK.register() is retrieved from PKPushRegistry as per guide
Running locally the Twilio Voice SDK successfully registers and retrieves APNs token
What is interesting is if I log in with exactly the same client account on an iOS 18.5 device (and an older iPad) call notifications work perfectly (I have made sure all focus modes/dnd are off and notification settings are identical)
The only changes myself and QA have made recently is minor iOS 18 version updates - 18.6.2 and 18.7.1
These now receive Invalid device token from APNs when Twilio attempts to create a call/voip notification for the user identity
Our devices sometimes switch environments test/prod so I installed the app cleanly on a borrowed 18.6.2 device and got the exact same issue
We have tested on these devices most of the year with no issues.
I have been in touch with twilio support and added code to explicitly unregister and re register on an affected device to clear any bindings but it didn't help.
Have apple made any changes in PushKit or token behaviour for later versions of iOS 18?
Thanks
Hey there,i start a live activity,but it not works, and sometime it can work;
apns-unique-id 46445cfa-1bf6-0f63-5ea3-2afa53e02b0d
and it show that "
2025年5月19日 GMT+8 15:13:25.836
received by APNS Server
2025年5月19日 GMT+8 15:13:26.244
discarded as application was not registered"
but i did not know how can i do;
thanks for you help
Problem
We have successfully set up push notifications using Apple APN service, that is push notifications work when using a token generated using the JSON Web Token Generator in the Push Notification console. However, we get an "InvalidProviderToken" error when creating using our own token using the following code.
The Key and TeamID is definitely correct (obviously, censored in the below code). When pasting our token in the JSON Web Token Validator in the Push Notification console we get the error „Invalid signing key“. We merely pasted our secret key in our setNewTokenIfNeeded code, separated on four lines using the “““ style.
Does anyone know why this error happens? Given that it works when we upload our .p8 file to the JSON Web Token Generator and we simply paste the text of this file (excluding the lines with "-----BEGIN/END PRIVATE KEY-----") I guess our secret key is correct?

On a similar note, some people seem to encounter this error when using the prettyPrinted option for the JSON serialization (i.e., in request.httpBody = try!

Many thanks!
