Linking text views to scroll together

I have two side by side text views. How can I link them so that if one is scrolled down other automatically scrolls the same as first one in swift 2.

Set your viewController conforms to UITextViewDelegate,then set textView delegate to self,then in scrollViewDidScroll sync both contentOffSet

For example Gif

enter image description here

Code

class ViewController: UIViewController,UITextViewDelegate {

@IBOutlet weak var textview2: UITextView!
@IBOutlet weak var textview1: UITextView!
override func viewDidLoad() {
    super.viewDidLoad()
    textview1.delegate  = self
    textview2.delegate  = self
    // Do any additional setup after loading the view, typically from a nib.
}
func scrollViewDidScroll(scrollView: UIScrollView) {
    if scrollView == textview1{
        textview2.contentOffset = textview1.contentOffset
    }else{
        textview1.contentOffset = textview2.contentOffset
    }
}

}
