> The most important question for every cross platform framework is what happens to the UI?
I kindly disagree. The first feature I want from a cross-platform framework is that it lets me write a native UI. That's why I like KMP: I can just share a framework with an iOS app built with SwiftUI.
Sharing business logic makes a lot of sense in a ton of cases and has been done forever (C/C++/Rust/Go libraries, etc). Sharing UI in complex apps, in my experience, always ends up being a "write once - debug everywhere" nightmare.
What KMP (and I'm hoping Swift for Android) bring is the possibility to share a Kotlin (respectively Swift) library instead of sharing code with C/C++/Rust/Go. So that an Android/iOS team can keep using Android/Swift without having to introduce a third language for sharing logic.
