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

I got this problem when I added the .plist to my target (Info.plist -> Get Info -> Targets -> Target Memberships). It went away when I unchecked it again.

I see that that's separate from the Targets -> -> Get Info -> Build -> Packaging -> "Info.plist file" -> my.plist that trips mentioned, but I still don't really understand what's going on, and definitely don't understand why we get such an unhelpful error message.
