UICollectionView error using Swift

Question

I am getting this error, trying to use a UICollectionView in Swift:

NSInternalInconsistencyException', reason: 'attempt to register a cell class which is not a subclass of UICollectionViewCell ((null))

But I think I am registering the cell:

1. ViewDidLoad:

   override func viewDidLoad()
   {
       super.viewDidLoad()
       self.collectionView.registerClass(NSClassFromString("CollectionCell"),forCellWithReuseIdentifier:"CELL")
   }
   

2. cellForItemAtIndexPath:

   func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath:NSIndexPath)->UICollectionViewCell
   {
      var  cell = collectionView.dequeueReusableCellWithReuseIdentifier("CELL", forIndexPath: indexPath) as CollectionCell
   
       cell.titleLabel.text="cellText"
       return cell
   }
   

and the cell class:

    class CollectionCell: UICollectionViewCell
    {

        @IBOutlet var titleLabel : UILabel
        init(coder aDecoder: NSCoder!)
        {
            super.init(coder: aDecoder)

        } 
     }

Any help appreciated

Answer 1

You need to pass your sub-class of UICollectionViewCell, in the Swift style, to registerClass:

self.collectionView.registerClass(CollectionCell.self, forCellWithReuseIdentifier:"CELL")

Answer 2

If your are not using any custom class just use in ViewDidLoad

myCollectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
