xcode build error

Hi, when I build my iOS game through unity and bring it into Xcode. The build fails and I get an error saying the following:

Couldnt register com.CompanyName.blahblah with the bootstrap server. Error: unkown error code. This generally means that another instance of this process was already running or is hung in the debugger.kill

What does this mean exactly? Can anyone help me. Thank you.

Whenever I get this message, I just quit out of xcode and then relaunch it. This usually solves the problem. If not, then restart your device and that definitely will fix it.

Means that you need to restart your device if you don’t have another xcode instance with connected debugger running
