4. Add an action to your sign up button that creates a user with the user's email and password using Firebase Authentication.

@IBAction func signUpButtonPressed(_ sender: UIButton) {
    guard let email = emailTextField.text, let password = passwordTextField.text else { return }
    Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
        if error != nil {
            // Handle sign up error
            return
        }
        // Sign up successful
    }
}

5. Handle any errors that may occur during the sign up process.
