Possible Error in Ch. 3 Regarding Carnivore WatchKit Extension

In “Chapter 3: UI Controls” page 62, it says:

  • Carnivore WatchKit Extension: This target houses all of the code that runs as an extension on your iPhone. Refer back to Chapter 2, “Architecture”, for more.

Isn’t that incorrect? In watchOS 1.0 the WatchKit extension ran on the phone, but no longer in watchKit 2? Right?
