I have BLE connection in my app and when the user quitted or the app become deactivated, I need to disconnect the connection. So I have to know if there is any method like “watchAppWillTerminate“ or something in WKExtensionDelegate.
The other thing is should I check this event from the "AppDelegate" or "ExtensionDelegate"?
P.S: The method "applicationWillResignActive" is not suitable for this issue because it is just for temporary interruptions.
