@Alivin solution using layoutAttributesForItemAtIndexPath works but only for the presented/current scroll view that the user sees.

Meaning, if you select the first presented visible cells you will get the actual frame, but if you scroll, the frame will have a deviation and you won't get the coordinates you need.

This is why you need to use convertPoint:toView :

let realCenter = collectionView.convertPoint(cell.center, toView: collectionView.superview)

Basically this method takes a point (cell.center) in one view and convert that point to another view (collectionView.superview) coordinate system which is exactly what we need.

Thus, realCenter will always contain the coordinates to the actual selected cell.
