如何使用firebase在xcode中验证电子邮件和密码

import Firebase

FirebaseApp.configure()

@IBAction func loginButtonTapped(_ sender: UIButton) {
    guard let email = emailTextField.text, let password = passwordTextField.text else {
        // 处理错误情况，例如输入为空
        return
    }
    
    Auth.auth().signIn(withEmail: email, password: password) { (user, error) in
        if let error = error {
            // 处理验证错误
            print("登录失败：\(error.localizedDescription)")
        } else {
            // 验证成功，执行相应操作
            print("登录成功")
        }
    }
}
