It’s happening. :)
I’m at a Swift hackathon!
Thanks to a little encouragement from (one of) my (two) friend(s named) Nick, I joined a Swift developer group and went to a meetup a few weeks ago. Then I signed up for the Hackathon meetup, took some (surprisingly awesome) web-based Swift classes, and today I managed (with some help from my fellow hackers) to use the CoreLocation framework and Google geocoding API to extend one of the class projects.
