Why is UICollectionViewCell's outlet nil?

I have created a custom UICollectionViewCell in Interface Builder, binded views on it to the class, and then when I want to use and set a string to the label on the string, tha label has a nil value.

override func viewDidLoad() {
super.viewDidLoad()

// Register cell classes
self.collectionView.registerClass(LeftMenuCollectionViewCell.self, forCellWithReuseIdentifier: "ls")
}

override func collectionView(collectionView: UICollectionView!, cellForItemAtIndexPath indexPath: NSIndexPath!) -> UICollectionViewCell! {

var cell: LeftMenuCollectionViewCell
cell = collectionView.dequeueReusableCellWithReuseIdentifier("ls", forIndexPath: indexPath) as LeftMenuCollectionViewCell
println(cell.label) // <- this is nil, why??
cell.label.text = "asd"

return cell
}


And the subclassed cell:

class LeftMenuCollectionViewCell: UICollectionViewCell {

@IBOutlet weak var imageView: UIImageView!
@IBOutlet weak var label: UILabel!
@IBOutlet weak var activityIndicatorView: UIActivityIndicatorView!
}

Answer

I am calling self.collectionView.registerClass(LeftMenuCollectionViewCell.self, forCellWithReuseIdentifier: "ls") again. If you are using a storyboard you don't want to call this. It will overwrite what you have in your storyboard.

If you still have the problem check wether reuseIdentifier is same in dequeueReusableCellWithReuseIdentifier and in storyboard.
