    // Our rounded button
    @IBOutlet weak var roundedButton: UIButton!
    
    // Push 'Start' button

        // Show progress indicator for our buttnon 
        roundedButton.showProgressIndicator(width: 5, color: UIColor.purple, backgroundColor: UIColor.lightGray, cycleDuration: 7.0)
    }
    
    // Push 'Stop' button
    @IBAction func pushStop(_ sender: UIButton) {
        // Hide progress indicator
        roundedButton.hideProgressIndicator()
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
  
        // Make rounded button
