I'm new to the swift language. I'm trying to use CollectionView but I'm running into some trouble. Here's the tutorial I am following.

but I can't get past 6:20 since this error message appears:

'Anyobject' is not convertible to 'UICollectionViewCell'

The only thing I did different from the tutorial is that I did not delete ViewerController class to change it to CollectionViewController.

Instead, I created a new class called CollectionViewController and followed step by step from then on. I did this because my CollectionViewController is to be added to an existing project and I don't want it to be the initial View Controller.

Let me know if you want to see my code. I only didn't paste it for simplicity

Thanks in advance

Try this code:

var cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! UICollectionViewCell

difference it as or as!. It's because of swift version.

If you're using Xcode 6.3 or later, you will need to use as! rather than as.

That's because Swift 1.2 change the downcast from as to as! or as?
