Flows in SwiftUI (preview) - Hot Flow

[carlosmonzon]

Hi

I was playing with Flows in SwiftUI and try to have a similar behaviour on android and iOS.
I created a simple ViewModel with the following code.

class TestViewModel: ViewModel() {

    val countState: SharedFlow<Int> = flow {
        var count = 0
        while (true) {
            count++
            emit(count)
            delay(1000)
            println("count $count")
        }
    }.shareIn(scope = viewModelScope, started = SharingStarted.Lazily, replay = 1)
}

And collecting using Observing on iOS

            Observing(viewModelStoreOwner.instance.countState.withInitialValue(0)) { uistate in
                Text("Click me! \(uistate)")
            }

On android, when resuming the app, the flow still active and emitting values and when the app is active again, the UI gets the latest values.

On iOS I am having a different behaviour, the flow stops emitting values while the app is in the background and start active again in the foreground.

Is this an intended behaviour? - It is worth mentioning that in this test I am using androidx viewmodel exposed on iOS.
