ios - Xcode 5 crashes -- Xcode quit unexpectedly

Question

Xcode 5 from the App Store crashes when I select any file in the Project Navigator or when I try to edit it. I have deleted all plugins and the derived data for the app and it keeps crashing.

Does anyone know how to fix this and why this is happening?

Below is the first part of the error.

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Application Specific Information:

I am not sure this helps but here is the Backtrace

Answer 1

I have also faced this problem. To prevent xCode5 from Crashing follow these steps. Xcdoe > Preferences > Source Control > Uncheck the Enable Source control . After that Xcode will not Crash .. :)
