I’ve now got an application called Notenik listed in the Mac App Store!
I’d been doing some regular programming in Java over the past couple of decades, but decided this year to bite the bullet and try to learn Swift, Apple’s latest development language, and chose the Mac as my first target platform. It’s been quite an adventure to create a full-fledged Mac App in a new language, but I’m happy to report that I’ve finally crossed the goal line! More improvements to come, but I believe that version 1.0 is quite serviceable. And it’s free!
