extension View {
    func makePreviews() -> some View {
        Group {
            ForEach(PreviewDevice.configs, id: \.name) {
                previewDevice($0.device)
                    .previewDisplayName($0.name)
                    .environment(\.colorScheme, $0.colorScheme)
            }
        }
    }

extension PreviewDevice {
    static var configs: [(device: PreviewDevice, name: String, colorScheme: ColorScheme)] {
        [
            (PreviewDevice(rawValue: "iPhone 11 Pro"), "11 Pro", .dark),
