Hello, is it possible right now to remove the background from the view passed in UIKitView in compose? I tried adding a transparency background in the modifier, in the background, but nothing helped

UIKitView(
    modifier = Modifier.background(Color.Transparent),
    background = Color.Transparent,
    factory = { someIconFactory() }
)

I also tried adding configuration to the ComposeUiViewController:

ComposeUIViewController(configure = { opaque = false }) {

that didn't help either

I just dealt with the ComposeUIViewController case, and the opaque = false worked for me. But there may be other views in the hierarchy that you have to set backgroundColor to .clear.
For the UIKitView case, I would check that the someIconFactory has the background set the way you want. "Debug ViewHierarchy" in XCode is your friend here.

For example, I am putting a ComposeUIViewController into a parent UIViewController as a container, so I have also do the following:

child.view.backgroundColor = .clear
        view.backgroundColor = .clear

where child is the wrapped ComposeView and view is the UIViewController I am creating and showing from other areas of my app.

Hi, thank you very much for your answer and tips,
Its strange coz I removed background from iOS chromecast icon for iOS but It still has a black background in the composeContainer.. Im rendering some image on that view and I want chromecast icon to be on the top of that image and take on the background color of this image. See screenshoots below

If you can see that in the Xcode view hierarchy, it is likely not a compose issue, but an issue with your image or its rendering mode or its backgroundColor
