I'm interested to see what Swift adoption will look like in the App Store going forward (now that it's at 1.0 [1]) especially on iOS vs. OS X. I wonder if it will be a glacial Carbon -> Cocoa style shift, or move faster thanks to the now-much-larger install base.

Swift is going to gain quick adoption. Why wouldn't developers move to a more modern language? The fact that you can easily integrate Swift with ObjC means it's easy to start. All the pre-release blogging is a good sign. I've gathered almost 100 links. I've got more that I'll add after my vacation. http://www.h4labs.com/dev/ios/swift.html

I looked into Objective C a bit last year but couldn't wrap my head around a lot of conventions. Swift on the other hand I'm looking forward to. That tutorial looks like it'll help :)

Interesting to see the migration process of an app from Objective C to Swift. I didn't know that an app can include both codebases at once.

It was covered in the main WWDC video. There's an Apple iBook. You can find the book on Apple's site.
