Answer 1

I have had this happen where I needed to restart the phone before error would go away.

Deleteing the app, restarting Xcode, clean build, didn't do anything. I shut the phone down and bought it back up and the error went away.

Answer 2

Most annoying bug. Only solution at this point:

If you're trying to run on a device: Shut off and restart device

If you're trying to run in simulator on Mac: restart your Mac

You can also do a Force Quit on the process via the Activity Monitor.
