I am trying to make an api call to fetch contents from server, when collection view is about to end scrolling.  
I plan to override  
override func collectionView(\_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {  
if indexPath.row == array.count - 1 {  
getNextSetOfData()  
}  
}  
this function of UICollectionView. How do I find out the protocol which is responsible to make this function work?  
I have delegates for collection.delegate, collection.dataSource, collection.UICollectionViewDelegateFlowLayout set and protocols implemented, but when I try to override func collectionView(\_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath), an error pops up - “Method does not override any method from its superclass”

Please delete this question. I figured out, had to delete override to make it work
