I have recently had an app rejected by Apple and when i attempted to make changes, my Main.storyboard was missing. I managed to delete the current reference and add an older version. After some tweaking, I restored the storyboard. (ALWAYS HAVE BACKUPS, KIDS)
I tried to run the new version, XCode could not find the first ViewController.

I have checked the box "Is initial ViewController" but to no avail.
