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

I received this error when the custom class (on Xcode inspector) still had its class set to the default UICollectionViewCell rather than my custom class for TestProject.CollectionViewCell.

To fix it, simply change the custom class to your implementation.
