Found it! When a system alert POP UP, then the function will be called [AppDelegate applicationWillResignActive:], after dismiss the alert then [AppDelegate applicationDidBecomeActive:] will be called. So, it can be detected by add a observer for notifications named UIApplicationDidBecomeActiveNotification and UIApplicationWillResignActiveNotification, such as [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(observeUIApplicationDidBecomeActiveNotification) name:UIApplicationDidBecomeActiveNotification object:nil];       [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(observeUIApplicationWillResignActiveNotification) name:UIApplicationWillResignActiveNotification object:nil];

Through research and investigation， the Notification Service Extension can receive remote notifications except silent notifications or those that only play a sound or badge the app’s icon by invoking - (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent *contentToDeliver))contentHandler

Remove the widget you config, and add it back again. It works for me.

Found a new target Matter extension. To add a matter extension new target can resolve this.

You should first use MatterSupport to commission your target matter device and make a matter extension target to get a new one payload then you use this payload to commission the device into your fabric.

https://developer.apple.com/apple-home/matter/ https://developer.apple.com/documentation/mattersupport/adding-matter-support-to-your-ecosystem Firstly, commission into apple ecosystem then in matter extension override func commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) async throws {} get payload to commission into your ecosystem.

Same issue. It always happens when new Xcode version and you haven't change the default deployment os version is target build General settings I found it may happens for many reasons, here will be one. Extension target version is higher than running device.(Minimum deployment version) For example , target setting 17.2 but running OS is 17.0 then it will fail for installing("Failed to get descriptors for extensionBundleID") Change to your supported minimum version or the running device that is satisfy the minimum version. Here my device is 17.0, I change the Minimum Deployments to 17.0 then running again success.

Here override func commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) async throws {} in Matter Extension(request handler), you can get a payload, use this payload to commission into your fabric.
