Screen jumps

[grosch]

When I do my long press, the entire screen "jumps" and then everything works like normal. It's very jarring visually. I only implemented two of your methods so far:

// MARK: - RAReorderableLayoutDataSource
extension HomeScreenViewController: RAReorderableLayoutDataSource {
func collectionView(collectionView: UICollectionView, reorderingItemAlphaInSection section: Int) -> CGFloat {
return 0.3
}
}

// MARK: - RAReorderableLayoutDelegate
extension HomeScreenViewController: RAReorderableLayoutDelegate {
func collectionView(collectionView: UICollectionView, atIndexPath: NSIndexPath, didMoveToIndexPath toIndexPath: NSIndexPath) {
let item = collectionData.removeAtIndex(atIndexPath.item)

    collectionData.insert(item, atIndex: toIndexPath.item)
}

}
