why does userDefaults not working in this code - ios

Question

import UIKit
class ViewController: UIViewController {
var nameInputTextField = UITextField()
var nameLabel = UILabel()
var button = UIButton()
override func viewDidLoad() {
super.viewDidLoad()
let storedName = UserDefaults.standard.object(forKey: "name")
if let userName = storedName as? String {
nameLabel.text = userName
}
let width = view.frame.size.width
let height = view.frame.size.height
nameInputTextField.placeholder = "Name"
nameInputTextField.borderStyle = .roundedRect
nameInputTextField.textAlignment = .center
nameInputTextField.frame = CGRect(x: width * 0.5 - width * 0.8/2 , y: height * 0.2 - height * 0.04/2, width: width * 0.8, height: height * 0.04)
view.addSubview(nameInputTextField)
nameLabel.text = "Your name: "
nameLabel.textAlignment = .center nameLabel.frame = CGRect(x: Int(width * 0.5 - width * 0.8/2) , y: Int(height * 0.3 - height * 0.04/2), width: Int(width * 0.8), height: Int(height * 0.04))
view.addSubview(nameLabel)
button.setTitle("Click to save", for: UIControl.State.normal)
button.setTitleColor(UIColor.blue, for: UIControl.State.normal)
button.frame = CGRect(x: width * 0.5 - width * 0.3/2, y: height * 0.4 - height * 0.06/2, width: width * 0.3, height: height * 0.06)
view.addSubview(button)
button.addTarget(self, action: #selector(ViewController.whenClicked), for: UIControl.Event.touchUpInside)
}
#objc func whenClicked(_ sender: Any) {
nameLabel.text = "Your name: \(nameInputTextField.text!)"
UserDefaults.standard.set(nameInputTextField.text!, forKey: "name")
}
}
Hello, I have been learning Swift, and I learned how to store data on the phone with userDefaults. I tried it with adding labels and textfields by drag and drop, but this time I decided to create those by writing myself, but this time code is not working (It's not saving the data). What is wrong?

The problem is that you set the text value of your nameLabel two times. Delete the
nameLabel.text = "Your name: "
line and consider the following suggestion:
if let userName = storedName as? String {
nameLabel.text = "Your name: \(userName)"
} else {
nameLabel.text = "Your name: "
}
