How to center a UICollectionView when it is tapped?

Question

I have a UICollectionView and it has quite a lot of UICollectionViewCells on it. I want to scroll the cell to the centre of the UICollectionView<

Answer 1

Swift 3 solution for scrolling and centering screen to make the tapped item visible:

override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
  collectionView.scrollToItem(at: indexPath, at: .centeredVertically, animated: true)
}

This doesn't add inset above or under the collectionView!
