Remarks

This interface contains the required methods (if any) from the protocol defined by UICollectionViewDropDelegate.

If developers create classes that implement this interface, the implementation methods will automatically be exported to Objective-C with the matching signature from the method defined in the UICollectionViewDropDelegate protocol.

Optional methods (if any) are provided by the UICollectionViewDropDelegate_Extensions class as extension methods to the interface, allowing developers to invoke any optional methods on the protocol.
