Hi, I'm trying to get banner ads showing in a list on iOS. I'm setting a callback from swift to kotlin to get a UIViewController factory for compose, setting this in swift and invoking it when I draw my list. The ads are clickable (they take me to the webpage), but are not being drawn. Code in 🧵 . Any ideas?

Kotlin

@Composable
actual fun GoogleAd() {
    UIKitViewController(
        factory = factory!!,
        modifier = Modifier.fillMaxWidth().height(100.dp).border(2.dp, Color.Blue),
    )
}

private var factory: (() ->UIViewController)? = null

fun setFactory(f: ()-> UIViewController){
    factory = f
}

Swift

Ads_iosKt.setFactory(f :  {() -> UIViewController in
            let ad = BannerAdView()
                .frame(width: GADAdSizeBanner.size.width, height: GADAdSizeBanner.size.height)
                .background(Color.red)
            return UIHostingController(rootView: ad)
            }
        )

I was going something with the graphics layer on a containing composable. This prevented the view from being drawn. This is working now.
