Ray Wenderlich's site now has a nice little tutorial on building a Bitcoin price tracking app using Swift:

WatchKit Tutorial with Swift: Getting Started

I tried it, got it running and scratched my itch!

P.S. You'll need to have Xcode 6.2-beta installed.

Nice, I'm working my way through this now. The bonus is this gives me a great opportunity to try out a bit more Swift. I've been reluctant to use it as production code but haven't really found the time to try it out so this is effectively killing two birds with one stone. Thanks! :D
