iphone - Unit tests failing to run after app rename due to apple linker error

Question

I recently changed the name of my app and now my unit tests are not running, I am getting an Apple linker error.

Any idea how to fix this? If I expand my 'Products' folder in Xcode there are 2 files:

MyApp.app MyAppTests.octest [which appears red]

Update: Deleted all the build folders (derived data) still doesn't work!
