Remarks

The extension methods for IUICollectionViewDragDelegate allow developers to treat instances of the interface as having all the optional methods of the original UICollectionViewDragDelegate protocol. Since the interface only contains the required members, these extension methods allow developers to call the optional members of the protocol.
