Taking first plunge with collection views and am running into this error:
Terminating app due to uncaught exception \'NSInternalInconsistencyException
I had the same problem. When I created a CollectionViewController, the default reuseIdentifier was Cell with capital C, but I made a mistake and made my cell identifier in Storyboard to be cell They must be the same.
reuseIdentifier
Cell
C
Storyboard
cell
