collectionView:cellForItemAtIndexPath: why my view has zero subviews?

Question

Please consider the following code:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("DataItemCell", forIndexPath: indexPath) as DataItemCollectionViewCell

    println("\(cell.parametersView.subviews.count)")

    return cell
}

and the view hierarchy of the cell:

I can't figure out why output is 0.

What I'm trying to achieve is to recursively loop through all descendants of parametersView.

I try to simulate a similar project and I had the same issue (my prototype cell wasn't used). Be sure that you don't have any

    self.collectionView.registerClass(UICollectionViewCell, forCellWithReuseIdentifier: reuseIdentifier)

or

    self.collectionView.registerClass(DataItemCollectionViewCell, forCellWithReuseIdentifier: "DataItemCell"DataItemCollectionViewCell)

anywhere in your code.

Usually, there is one in the func viewDidLoad() function.

Edit:

Send me an exemple by mail, if you still have the problem.
