As far as I know they are all the same course, just new editions for each batch of students (and by coincidence, each new iOS versiopn).
I followed it when it was still objective c, and I can only assume it gets better each time. As long as it's still the excellent Paul Hegarthy holding it, just use the latest one.
If you use the Itunes U app on the ipad you'll get all the exercises etc in a nice format. And at least when I did it there was even a special forum for all the MOOC students to discuss the lectures and exercises.
I can't recommend this course enough, it's one of the best I've ever come across, any category.
Swift 4 and iOS 11 are coming soon, but I wouldn't wait for the course to get updated. Downside of it being a university lecture is that it'll be a while.
