I am trying to move from xcode 3.1 to 4.1 and in the process, I installed Xcode 4.1 and opened project I created with Xcode 3.1. But when I build project, it gives error:
The document "filename.xib" could not be opened. The operation couldn’t be completed. * -[NSCFArray insertObject:atIndex:]: attempt to insert nil.
The file is not full screen View with status bar, it is freeform view.
Thanks, Jignesh
