Command failed due to signal: Segmentation fault: 11

Answer 1

A segmentation fault while compiling is a bug in the compiler. Nothing you do from Xcode should cause the development environment to crash.

I suggest you upgrade to the release version of Xcode 6.3 and try again. If it still crashes on compile (not on run, on compile) then submit your app to Apple in a Radar bug report:
