Issue

Couldn't register com.livrona.apps.FH with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.(gdb)

Solution

Try the following things in the below order:

- Make sure all only one program is being debugged in XCode, close other running instances.

- Restart XCode, most of time this is take care of the issue.

- If you are running this on the device and is still not working restart the device and try again.
