Since the release of XCode 4.2 I have noticed a certain error poping up after buidling reguarly. The error incidcates that the iOS Simulator already has a process running or is hung. The anoying part is that even if you quit XCode and iOS Simulator, the problem wont go away.
This is the error:
Couldn’t register com.myApp.debug 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.Program received signal: “SIGABRT”.
