Hi all
I tried to add

implementation("com.badoo.reaktive:rxjava3-interop:1.3.0")

into compose-multiplatform-ios-android-template
and I am getting errors..

Could somebody help to figure out with it ?

RxJava interop is only available for JVM and Android, because RxJava is a Java library. It can't be used in a shared code targeting non-Java platforms.

[Dmitry Motyl]

Oh, you are right
I missed it
Thank you!

[Dmitry Motyl]

@Arkadii Ivanov what is about coroutines interop ?
It should be for iOS ?

[Dmitry Motyl]

I mean in theory. I see that now it is not supported

[Arkadii Ivanov]

Yes, it should work for iOS. Please check the readme, as there are some tricky things.

[Arkadii Ivanov]

It is supported

[Arkadii Ivanov]

Assuming you are using the new memory model, if you are using Reaktive v1.x then you should use -nmtc version of coroutines-interop module (e.g. com.badoo.reaktive:coroutines-interop:1.3.0-nmtc. With Reaktive v2.x it should just work.

[Dmitry Motyl]

I use Reaktive v2

I see that problem with androidx.compose.runtime/collectAsState

I am trying to use Reaktive with iOS Compose like that

@Composable
fun StringListView(
    viewModel: ListViewModel<String>
) {
    val items = viewModel.items.asFlow().collectAsState(emptyList())
....

[Arkadii Ivanov]

Well. You could just write your own collectAsState for Observable and/or BehaviorObservable. So that you don't need to use the coroutines interop at all.

From the top of my head.

fun <T> Observable<T>.collectAsState(initialValue: T): State<T> {
  val state = remember(this) { mutableStateOf(initialValue) }

  DisposableEffect(this) {
    val disposable = subscribe { state.value = it }
    onDispose(disposable::dispose)
  }

  return state
}

fun <T> BehaviorObservable<T>.collectAsState(): State<T> =
  collectAsState(value)

But your approach should also work. What's the error?

Oh, I believe there are multiple similar known issues with Compose for iOS! The first thing is to try a workaround from https://github.com/JetBrains/compose-multiplatform/issues/2046. If doesn't help, you could search and/or ask #compose-ios.

[Dmitry Motyl]

looks like problem was that “shared compose ios framework” can be only static if you use cocoapods for integration

[Dmitry Motyl]

your workaround helped, thank you!
static framework was a second problem 😃
