Hello!

Thanks for the question and good news, we have a way of doing that. You can use the MapViewReader  to access the proxy which has operations for the MapView. And on that proxy we have a method to export an image of the current map. Like this:

var body: some View {
    MapViewReader { proxy in
        MapView(map: map)
            .task {
                // This will export the image when the view appears
                // but I recommend putting this code where you want
                // to take the screenshot.
                let screenshot = try? await proxy.exportImage()
            }
    }
}
