Discussion
Use this method to handle actions selected by users from your notification interfaces. If your containing iOS app supports interactive notifications, the identifier parameter may contain the action identifier for the button that was tapped. Use that value to perform the requested action. If the identifier parameter contains an empty string, that means the user launched your Watch app from the notification interface without choosing a specific action.
The system calls this method on your WatchKit extension’s main thread. The super implementation of this method does nothing.
