I've followed this tutorial to build the view:

Answer 1

You can find the point of your cell by using:

let realCenter = collectionView.convert(cell.frame, to: collectionView.superview)

But if this will give you with respect to the collectionView . If you need to find the centre with respect to main view , you need to go through all the superview .

let realCenter = collectionView.convert(cell.frame, to: collectionView.superview?.superview?.superview?.superview)

loop through the views to find your superview you are looking for and then find the frame
