    let name: String
}

// 構造体　→　Data にしてをUserDefaultsに保存
let user = User(id: 12345, name: "kentarou")
let data = try? JSONEncoder().encode(user)
UserDefaults.standard.set(data, forKey: "user")

//　UserDefaultsからData　→　構造体 にして読み込み
if let udData = UserDefaults.standard.object(forKey: "user") as? Data,
    let user = try? JSONDecoder().decode(User.self, from: udData) {
    print(user.id) //=> 12345
    print(user.name) //=> kentarou
}
