> Can you actually write a Preferences panel in Swift? I wouldn’t be surprised if the answer were “nope, Obj-C only”.
If that was the case (I don't believe it is), it would only be because modern Apple doesn't care enough about Preference Panes to add easy support. A third party Preference Pane is not any more "OS machinery" that a third party screen saver.
