I had collectionViewCell blank problems until i realized my viewController was not in file i did not know how this file was end up trash it took me while to figure it out.

Answer 3

Problem is with setting the title to button, use the following code.

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

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

        var button = cell.viewWithTag(1) as! UIButton
        //button.titleLabel?.text = Array[indexPath.row]
        button.setTitle(Array[indexPath.row], forState: UIControlState.Normal)
        return cell
}
