Swift | CommuniCrossings

I am currently learning Apple's Swift language for iOS and OS X,
using the XCode development framework.
Current prototype apps include:
Pico Fermi Bagels (my usual initial learning exercise, e.g., JavaScript, NewtonScript, etc.)
'Enneagram mapping'.
Someday, I may finish these/others and distribute thru Apple's App Store.
If there's enough interest (and I have time), I may offer a programming history and/or how-to course at OLLI, e.g., Let's Program an App
