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