- iOS 6.0+
- Mac Catalyst 13.0+
- tvOS 9.0+
The coder object to use to decode the state of the view.
If your app supports state restoration, you should override this method for any views for which you also overrode the
encode method. Your implementation of this method should use any saved state information to restore the view to its previous configuration. If your
encode method called
super, this method should similarly call
super at some point in its implementation.
