Hey guys, I am trying to use a SwiftView on top of my Composable Screen, a SwiftUI Text() using UIKitViewController. However, it always seems to add a White background to it. I understand there’s a active issue for it but is there a workaround for it?

val factory = LocalNativeViewFactory.current
UIKitViewController(
    modifier = modifier
        .width(100.dp)
        .height(50.dp),

    factory = {
        factory.createTextView(
            label = "IOS Text",
        )
    }
)

struct SimpleIOSText: View {
  var label: String
   
  var body: some View {
  
      Text(label)
        .font(.headline)
     
  }
}

this is a simpler example of what i want to do. My usecase is using .stroke() api in swift and using it on top of my Compose View nackground

Transparency is not supported in interop views. It won't be changed in short-term

See my explanation in the previous thread - https://kotlinlang.slack.com/archives/C0346LWVBJ4/p1742458773528449?thread_ts=1742395588.034329&cid=C0346LWVBJ4

Issue to track - CMP-3154

This idea is a hack, but maybe you could draw the swift view on top of the compose view in the host view controller, and sync it using Modifier.onGloballyPositioned (making the compose version just a transparent Box) by writing to some sort of view position registry CompositionLocal and make that set the swift view's location to match?
