Load local html files from applications's document directory swift wkwebview

I am trying to load a local html file which is downloaded to my application with wkwebview. Along with this html file i am downloading two js files, they are referenced inside the html file.

But what ever i do, they are not loading in wkwebview 

 @IBOutlet var webView: WKWebView!
    @IBOutlet var act: UIActivityIndicatorView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Adding webView content
        webView.uiDelegate = self
        webView.navigationDelegate = self


let fm = FileManager.default
    let docsurl = try! fm.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
    let myurl = docsurl.appendingPathComponent("index.html")
    print("my url = ",myurl )
// myurl prints file///var/some directories/index.html
let request = URLRequest(url: myurl!)
            webView.load(request)
}

My html file

<!DOCTYPE html>
 <html> 
<head>
<script src="jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("button").click(function(){
    $("p").hide();
  });
});
</script>
</head>
<body>

<h2>This is a heading</h2>

<p>This is a paragraph.</p>
<p>This is another paragraph.</p>

<button>Click me</button>

</body>
</html>

But it is not loading on the screen from safari(Develop/) i can see that An error occured trying to load the resource, page is coming as about:blank

URLRequest is basically made for live url. For system file just load the URL. You need to use below method and it will work:

/*! @abstract Navigates to the requested file URL on the filesystem.
     @param URL The file URL to which to navigate.
     @param readAccessURL The URL to allow read access to.
     @discussion If readAccessURL references a single file, only that file may be loaded by WebKit.
     If readAccessURL references a directory, files inside that file may be loaded by WebKit.
     @result A new navigation for the given file URL.
     */
    @available(iOS 9.0, *)
    open func loadFileURL(_ URL: URL, allowingReadAccessTo readAccessURL: URL) -> WKNavigation?

So that:

self.webView.loadFileURL(myurl, allowingReadAccessTo: myurl)
