Sets whether the view controller shows an editable view.
Mac Catalyst 13.0+Beta
If true, the view controller should display an editable view; otherwise, false.
If true and one of the custom views of the navigationItem property is set to the value returned by the editButtonItem method, the associated navigation controller displays a Done button; otherwise, an Edit button.
If true, animates the transition; otherwise, does not.
Subclasses that use an edit-done button must override this method to change their view to an editable state if isEditing is true and a non-editable state if it is false. This method should invoke super’s implementation before updating its view.
Returns a bar button item that toggles its title and associated state between Edit and Done.
