struct User: Decodable { let id: Int; let name: String }

func fetchUser() {
    let url = URL(string: "https://api.example.com/user/1")!
    let task = URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else { return }
        if let http = response as? HTTPURLResponse, http.statusCode == 200 {
            let user = try? JSONDecoder().decode(User.self, from: data)
            print(user?.name ?? "No name")
        }
