Scrolling image in SwiftUI

Hi, why doesn't this view scroll? The image is taller than the screen.
Code Block
struct ImageScroll: View {
    @State var uiImage: UIImage
    var body: some View {
        ScrollView {
            Image(uiImage: uiImage)
                .focusable()
        }
        .focusable()
    }
}

Thanks,
Spiff
Sorry, I neglected to mention that this is on tvOS though the focusable() calls indicate so.
