How to disable horizontal scrolling in webView with swift?

Question

I have a simple webView like :

@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
    super.viewDidLoad()

    let url = "https://developer.apple.com/library/mac/documentation/Swift/Conceptual/Swift_Programming_Language/TheBasics.html#//apple_ref/doc/uid/TP40014097-CH5-XID_456"
    let requestURL = NSURL(string:url)
    let request = NSURLRequest(URL: requestURL!)
    webView.loadRequest(request)

when I load this request into webView it loads perfectly fine but when Its load completely It scroll horizontally like this when I scroll it from left side and right side:

I don't want to scroll it this way and I only want it to scroll vertically is there any way to do it in swift I search on Internet but only found solution for objective-c and I try this in swift but not working.

Please provide me any solution for this.

Update Swift 4

Add both these methods into your UIViewController:

    func webViewDidFinishLoad(_ webView: UIWebView) {
    self.webView.scrollView.showsHorizontalScrollIndicator = false
}

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    if (scrollView.contentOffset.x > 0){
        scrollView.contentOffset = CGPoint(x: 0, y: scrollView.contentOffset.y)
    }
 }

in the viewDidLoad Method add these lines:

 webview.scrollView.delegate = self
 webview.scrollView.showsHorizontalScrollIndicator = false

Now this wld show an error at line webview.scrollView.delegate = self so make sure you add the UIScrollViewDelegate like this

class DetailViewController: UIViewController, UIWebViewDelegate, UIScrollViewDelegate{

And horizontal scrolling has stopped :)
