iPhone: Failed to launch simulated application: Unknown error

Question

This is a new iPhone project, only 1 target (different from this question)

On build we get:

Failed to launch simulated application: Unknown error.
         


        

Answer 1

This might be because items are missing for the target. Expand the target and verify that all needed source files and libraries are there. Restart Xcode after you've messed around.
