The following happens regularly. I have to clean all to fix. And sometimes restart VS.
The output says starting debugging session. The app launches on the device.  Nothing from the app goes to the console output. And no breakpoints hit.

Same problem here...

Verified this bug with Xamarin.iOS for VS 1.6.60.msi

Actual Result:
Debugger does connect and breakpoint gets hit while deploying an ioS app to a device. 
However, user is not able continue with debugging, since the app comes out of the session within a few seconds. The issue is only partially fixed.

This is the iOS behavior, when the application starts you have around ~30 sec to return FinishLaunching() if  you take too long iOS will kick out your App.

This will happen with XS as well. http://screencast.com/t/IFEU1LkQ5G

Thanks Jarina. I made a mistake in setting the first break point. Verified the bug again with the latest build 1.6.71 and debugging on device is working as expected. Marking the bug as resolved fixed.

Test Env:
Xamarin.iOS 1.6.71.msi

Just to be clear, the timeout is closer to ~20seconds before the OS kills it.

Today I have checked this issue with following builds:

All Windows
VS 2013/2012/2010
iOS for VS 1.8.294

Now we are successfully able to deploy application on device when using breakpoint in application and not seeing 'Debug session ended'. This is the screencast for the same: http://screencast.com/t/r4rPXXfOimu

Changing the status to Verified.
