I'm implementing undos in an app using CoreData. My app also uses State Restoration.
What's not clear to me from the docs is if the NSUndoManager will persist its undo history between launches / state restoration? It's not a major issue if it doesn't, it's just I need to know so I can code for it accordingly.
It does not. It also does not support NSCoding or NSSecureCoding, so there appears to be no way to archive it yourself.
