Hi all, I was trying out Compose ios (alpha) and got stuck at one point. I needed to consult you for your opinion. I am attaching a screenshot that shows a small part of both iOSApp and Android App project. Attached you can see viewModels , Activity/ContentView.
Just like Android, I am trying to update the content on iOS, but it’s not working by using binding<state> etc.
How can I get the redraw action on iOS?
Any ideas or examples would be very helpful :) Have a nice K / K cheers

you can create a state and store it in
val stateFlow = MutableStateFlow<YourState>(...)

After that - you can subscribe to state changes with in Composable function with:
val state = stateFlow.collectAsState()

And draw that state:
Text(state.value.toString())

state.value will have a type of YourState

It appears you are using KMPNativeCoroutines. Then on the Kotlin side, put @NativeCoroutinesState above your val state. Then on the iOS side wrap the generated stateFlow with the KMPNativecoroutines.createObservable method, then use the RxSwift observe methods...

Thanks all,

The requirement is , updating the ComposeUIView by using ViewModel.swift: ObservableObject. Fetching data is OK but updating it. I’m able to draw a composeView with default state , and it never gets updated 🙂
I need a trick which refreshes my rootComposable

Also, you can simply use in Kotlin Composable functions:
val state = remember{ mutableStateOf(MyState()) }
Read and change this state state.value
