11. Add following code to view did load. When app is opened then by default segment 0 is selected.

    override func viewDidLoad() {
        super.viewDidLoad()
        // 11
        segment.selectedSegmentIndex = 0
        
        content.text = "New segment feature is included"
        
        // Do any additional setup after loading the view, typically from a nib.
    }

12. Add following code to index change button

    @IBAction func indexChanged(sender: UISegmentedControl) {
        // 12
        switch segment.selectedSegmentIndex {
            
        case 0:
            content.text = "New segment feature is included"
        case 1:
            content.text = "We make iPhone apps"
        case 2:
            content.text = "apoorv@apoorvmote.com"
        default:
            ()
            
        }
        
    }
