It's only two lectures, so far. Maybe wait until the whole course is up before giving a review?
(Stanford has some older iOS programming courses up on iTunes as well. For example, the course "Developing iOS 7 Apps for iPhone and iPad" [1] is 18 lectures.)
Of course it's too early to know for sure, but judging from the superb quality of Paul Hegarty's previous iOS programming courses, this course will probably become the best learning resource for wannabe iOS developers.
Would you have a few mins. today to talk by phone or email about your experience with Swift and/or this course? I'm writing a news release for Stanford News and would like a couple of user quotes.
Thanks for Swift reply to redwoodfroggie at gmail dot com, or (760) 709-6599.
