Trigger UNNotificationServiceExtension on Simulator via Xcode 11.4 push feature

Question

Xcode 11.4 (beta) allows developers to trigger push notifications on the simulator. I'm currently doing this via command-line using:

xcrun simctl push [device] [my.bundle.identifier] payload.apns

However I also have some UNNotificationServiceExtension that loads an image from an external URL given in a custom field of the payload. The image is then displayed in the notification popup. Unfortunately this extension is never called using the given command-line.

I also tried to use the bundle identifier of the extension in the command-line, but that just doesn't do anything.

I am aware that Xcode 11.4 is still in its first beta, but did anyone discover a way to trigger a notification service extension using this new feature?

Answer 1

Certain kinds of notifications are not currently supported, including service extensions and VoIP.
