Could not cast value of type 'UICollectionViewCell'

Question

I use a custom CollectionViewCell in my Storyboard. When I start the app I get this message:

Could not cast value of type \'UICollectionViewCell\' to T

Answer 1

 self.collectionView!
     .register(MyCollectionViewCell.self, 
               forCellWithReuseIdentifier: reuseIdentifier
              )

You don't have to delete this line. You will register your own cell class inherited by UICollectionViewCell.self if you want to register class using code
