Try this out:

func collectionView(_ collectionView: UICollectionView,layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
if collectionView == verticalCollectionView {
let size = CGSize(width: collectionView.bounds.width, height: collectionView.bounds.height)
        return size
    }
let point = CGPoint(x: self.view.frame.size.width/2.0, y:35 )
//or you can try this code also
//let point = CGPoint(x: UIScreen.main.bounds.width/2, y:35 )
    print(point)
let centerIndex = self.collectionView.indexPathForItemAtPoint(point)
    if indexPath.item == centerIndex {
        return CGSize(width: 70, height: 70)
    }
    return CGSize(width: 50, height: 50)
}

This code gives you the index of the item at the center of the collection View. Hope this helps
