在新的Firebase和Swift中创建用户

pod 'Firebase/Auth'

pod install

import Firebase

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    FirebaseApp.configure()
    return true
}

import FirebaseAuth

func createUser(email: String, password: String, completion: @escaping (Result<User, Error>) -> Void) {
    Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
        if let error = error {
            completion(.failure(error))
            return
        }
        
        guard let user = authResult?.user else { return }
        completion(.success(user))
    }
}

@IBAction func signUpButtonTapped(_ sender: UIButton) {
    let email = emailTextField.text ?? ""
    let password = passwordTextField.text ?? ""
    
    createUser(email: email, password: password) { result in
        switch result {
        case .success(let user):
            print("User created successfully: \(user.uid)")
            // 用户创建成功，可以进行下一步操作，例如导航到主屏幕
        case .failure(let error):
            print("Error creating user: \(error.localizedDescription)")
            // 处理错误，例如显示错误消息
        }
    }
}
