Area: UIKit Summary: UIDragDropSession.allowsMoveOperation & restrictedToDraggingApplication are "determined based on the UIDragInteraction's delegate's `-dragInteraction:sessionAllowsMoveOperation:` & `-dragInteraction:sessionIsRestrictedToDraggingApplication:`. There should be corresponding delegate methods in UITableViewDragDelegate & UICollectionViewDragDelegate to configure these properties. Otherwise it's impossible to implement copy-only operations or intra-app only drag-n-drop on UITableView or UICollectionView.
