Forces the context to process changes to the object graph.
UIKit for Mac 13.0+Beta
This method causes changes to registered managed objects to be recorded with the undo manager.
In AppKit-based applications, this method is invoked automatically at least once during the event loop (at the end of the loop)—it may be called more often than that if the framework needs to coalesce your changes before doing something else. You can also invoke it manually to coalesce any pending unprocessed changes.
Sends a redo message to the context’s undo manager, asking it to reverse the latest undo operation applied to objects in the object graph.
