 <p>Can't tell you how frustrated I am trying to narrow down the cause of this one. Took me hours. Trial and error here and there.. all leads to nothing until one comment in one of the threads relating to this mentioned about "Executable". Boom! I remember the plist key "Executable file" in my project plist (PROJECT-info.plist). So I got there and found out that that entry was missing. I filled it in with whatever default you see when creating new project, "Executable file" paired with "${EXECUTABLE_NAME}". Build + Run. Then it finally worked! </p> <p>Btw, I did try all those deleting/resetting stuff found all over SO. None of them works. </p>
