title: Swift iOS- How to hide label then make it appear after a certain time period
body: <p>I have a label that gets hidden when a button is pressed. After a certain time period like 60 secs I want the label to reappear. I'd assume I do that in viewDidAppear, How would i do that?</p>
  
  <pre><code>@IBOutlet weak var myLabel: UILabel!
  
  override func viewDidAppear(_ animated: Bool) {
          super.viewDidAppear(animated)
         //after 60 secs myLabel should reappear
         //self.myLabel.isHidden = false
      }
  
  
  @IBAction func buttonTapped(_ sender: UIButton){
         self.myLabel.isHidden = true
  }
  </code></pre>
