Couldn\'t register com.XXXXX.deviceapp with the bootstrap server.

Answer 1

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.
