I'm working on software that isn't source-available (as of now, anyway). I've written an app that is aimed at a specific demographic (so I'm not linking to it), and I'm developing an improved backend admin app. This involves mostly Swift, using UIKit, to produce an app that will run on iOS, iPadOS, and MacOS. The backend is PHP, and doesn't need much work.
