ios - 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.platform/Developer/usr/bin/ibtool failed with exit code 255

I get this error for a whole bunch of my xib files. Any ideas what is happening, and what a solution is?

Using Xcode 4.6, iOS 6.1.

Answer 1

I had something similar happen to me recently using Xcode 4.6 and iOS 6.1.

All I did was switch to a different device version (5.1) on the simulator and it ran. Switched back to 6.1 and it fixed itself.

Xcode can be unhelpful at times.
