you can call java script function when webview didfinishload, before that your javascript function is not called..

import UIKit

class yourViewController: UIViewController, UIWebViewDelegate {

    @IBOutlet var webView : UIWebView

    var url = URL(string: "https://xyz.aspx")

    override func viewDidLoad() {
        super.viewDidLoad()

        //load initial URL
        var req = URLRequest(URL : url)
        WebView.delegate = self
        webView.loadRequest(req)
    }
    func webViewDidFinishLoad(webView : UIWebView) {
         WebView.stringByEvaluatingJavaScript(from:"LoginByMobileApp()")
    }
}

@ Er. Khatri check the image in top of the question.

you have done it using WKWebView.., you can also use UIWebView to call javascripts in iOS

@jakirhussain try the above answer once.., I am sure your LoginByMobileApp() function will be successfully called

You could use evaluateJavaScript function for WKWebView.

let javaScriptString = "YOUR_JAVASCRIPT_FUNCTION"

 webView.evaluateJavaScript(javaScriptString, completionHandler: nil)

I'm using @IBOutlet weak var WebView: UIWebView!

You cannot do it using UIWebView. Migrate to WKWebView.
