如何检查UITextField的文本是否是有效的电子邮件？

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var emailTextField: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func checkEmailButtonTapped(_ sender: UIButton) {
        if let email = emailTextField.text {
            let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"
            let emailPredicate = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
            if emailPredicate.evaluate(with: email) {
                print("Valid email")
            } else {
                print("Invalid email")
            }
        }
    }
}
