Tangent but I'm holding out from learning Swift until I see how the "Cross platform UI" wars shake out. We've got at least Kotlin, Dart, and JavaScript all battling it out (via Kotlin Multiplatform, Flutter, React Native) to be the king of UI languages across all platforms. I really like Swift though (from the little I've learned), so it's too bad it doesn't really have a cross platform UI story yet.
(I could learn all four but I have kids, so it'll probably just be React Native for me.)
