    let rows = [GridItem(.fixed(30)), GridItem(.fixed(30))]

    var body: some View {
        ScrollView(.horizontal) {
            LazyHGrid(rows: rows) {
                ForEach(0x1f600...0x1f679, id: \.self) { value in
                    Text(String(format: "%x", value))
                    Text(emoji(value))

                }
            }
        }
    }

    private func emoji(_ value: Int) -> String {
        guard let scalar = UnicodeScalar(value) else { return "?" }
        return String(Character(scalar))
    }
