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 face this problem , because in the viewDidLoad() I registered my cell with UICollectionViewCell class . In my cellForItemAtIndexPath used CustomSubcalssCollectionViewCell for dequeueReusableCell.

make sure registerClass and dequeueReusableCell are the same class solve the problem

self.registerClass(SomeUICollectionCellClass.self, forCellWithReuseIdentifier: reuseIdentifier)

let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! SomeUICollectionCellClass
