Thinking about making my SwiftUI code cross platform, beyond Apple.

I don’t really want SwiftUI on every platform and dealing with the impedance mismatch of SwiftUI and the host - despite having a few OSS engines that do it.

What I have come to realize is that using SwiftUI @Observables is all you need: swap the actual front end for a tightly coupled UI to the host platform, but keep your logic shared.

And you can have an LLM do the heavy lifting for you.

@Migueldeicaza I’m using Xamarin/ now Maui for some years and in theory it’s how you describe it. Back with Xamarin it was two apps, each with its own “native” UI bound to the core logic that’s used by both apps, then with .forms / now Maui it’s “the same” UI which is nice.

But in reality it’s still adding platform specific code and handling. Navigation stack handled differently, Modal acting differently, statusbar, toolbar, navigation bar, accidental double touches …it’s quite some extra work
