Why am I getting ibtool failed with exit code 255?

Question

All of a sudden I can\'t build my project. I get the following compiler error:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.pl

Answer 1

I was working within a secondary git branch when I encountered the '255' problem.

I merely switched back to my main git branch, cleaned the project and run. No problems as I had expected.

Then I switched back to the 'problem' git branch and rebuild it with success.
