问题
I have an extremely annoying problem! Xcode 7 crashes almost on every breakpoint when it tries to symbolicate.
I have done several things including deleting Xcode and reinstalling it...
I also had the same issue on the previous Xcode 6.X
Any clue? I am wondering if I should reinstall mac OS from scratch...

I solved the issue by changing the optimization level in the build settings, make sure it is set to None for Debug configuration and make sure your RUN scheme uses Debug configuration.
