Check out kotlin compose multiplatform. Takes the Android declarative jetpack compose UI framework and makes it run cross platform. You get most of the modern UX conveniences from Android, can reuse libraries etc. Works with either JVM or compiling to native code too.

Turbine is fantastic. I've had an eye on zipline because it solves a deployment issue I face (we deploy to enterprise devices which don't have an app store or MDM so need manual app updates that take a few weeks to co-ordinate).

Redwood also looks very promising as a correct way to do cross platform UI.

Great that it's finally 1.0! Zipline as well! I didn't know they were doing a summer of kotlin multiplatform. Keep posting updates!
