Instance Property


A Boolean value that indicates whether the collection view contains drop placeholders or is reordering its items as part of handling a drop.


var hasUncommittedUpdates: Bool { get }


When the value of this property is true, avoid making any significant changes to the collection view. Specifically, do not reload the collection view's data, as doing so deletes all placeholders and recreates items from the data source.
