I'm seeing this error at random times. When it starts happening, it happens consistently unless I restart VS. The issue is that when the app is launched, debugger stops with a message in the console:
Launching 'AppXiOS' on 'xyz's iPhone'...
Launched 'AppXiOS' successfully on 'xyz's iPhone'...
The app has been terminated.
iOS device keeps running the app, but VS has no connection to it anymore.
