Product:Developer Tools Product Version:Xcode6-Beta5 (6A279r)
Classification:Serious Bug Reproducible:Always
 
Summary:

Running an executable for debugging results in the message:

    2014-08-26 09:56:22.887 Test Harness[52342:10057425] Unable to load nib file: MainMenu, exiting

Removing the derived data folder fixes this problem.

I have not found a repeatable method for causing this problem, but it happens periodically.

Simple run an application from within Xcode.

Regression:

This is an XC6 problem.
