Are “Notification Service Extensions” officially supported on macOS?
I’m developing an app for both iOS and macOS (not Catalyst). I’ve successfully setup a separate notification service extension for both the iOS and macOS targets. The iOS extension is modifying the CKSubscription push notification as expected. However the macOS notification service extension is not being launched at all no matter what I seem to try, matching deployment targets etc.
I’m also asking because although Apple docs report that support for UNNotificationServiceExtension was added in macOS 10.14, the article at https://developer.apple.com/documentation/usernotifications/modifying_content_in_newly_delivered_notifications makes no mention of macOS, only iOS.
