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

Changing the product name worked for me. I tried several different alternatives and all of them worked fine. It was the "magic product name" I used at the onset that failed every time I went back to it. YMMV.
