Are there any recommendations on how to use Multiplatform ViewModels with Swift Export yet?

[François]

That's a good question, I’m trying to migrate my playground from skie to swift export and that’s not easy.

Some API that’s kotlin can export easily in objc can’t be in swift

FWIW AI spit this out for me. Has been working pretty well so far *extension* View {

/// Mirrors a Kotlin StateFlow into binding for as long as the view is alive.
///
/// Swift export bridges StateFlow as an AsyncSequence, so views keep a plain
/// @State copy of the latest value instead of observing the ViewModel itself.
*func* mirroring<Element>(
_ flow: *any* KotlinTypedStateFlow<Element>,
into binding: Binding<Element?>
) -> *some* View {
task {
*do* {
for try *await* value *in* flow.asAsyncSequence() {
binding.wrappedValue = value
}
} catch *is* CancellationError {
// Expected when the view's task is torn down.
} *catch* {
assertionFailure("StateFlow observation failed: \(error)")
}
}
}
}

It’s totaly possible to reproduce SKIE with the flow, your snippet is a little example.

Does Skie support swift export?

[François]

No, it won’t.

By reproducing, I mean the behavior of SKIE but with Swift export.

Hello there. The simplest way to connect androidx Vm with SUI is something like this - github.com/joreilly/PeopleInSpace/pull/524/changes#…, as demonstrated by @John O'Reilly (quite close to the snippet made by your AI)

In our tutorials for using androidx VM from SUI we as Kotlin Ecosystem actually recommend using github.com/rickclephas/KMP-ObservableViewModel by @Rick Clephas, as it helps with a lot of boilerplate.

RN we are discussing, what would be the correct approach of providing a support for KMP-ObservableVM inside the Swift Export, stay tuned 😉 But no timeframe on that integration
