Like many of the prior 'MainStoryboard missing in NSBundle' questions, I've got the same prompt but have found no issue with naming and no issue with if the storyboard exists within an area XCode likes.
All the pointers lead to the same file, I've changed my .plist a good 5 times to make it responsive to the same call as found in Build Stages. Now I'm all kinds of tired of this crap because I just want to program, not debug compiler screw ups.
It happened in an instant and now I've been a day and a half without an interface that works. How should I proceed?
I got the following similar error in XCode 4.3.3:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'MainStoryboard'
I fixed it by doing the following:
-info.plisthas Main story board file based name =
en.lprojfolder in your projects directory and add it
Got the idea from this SO post: XCode 4.2 MainStoryBoard Not Found
