Interesting. I used Expo recently and loved the development experience. I also built a simple iPhone app with Swift, and it was a decent experience. I have plans of building another iPhone app and was considering Swift again, which would make me miss building an Android app, but maybe Skip would allow me to do it anyways.
Biggest downside to SwiftUI development is lack of hot reloading. You can use the Inject framework but it’s fragile. This also makes it harder to iterate on with agents.
