What have you tried — how are you displaying this webview? — Chris Droukas, Mar 22 '17 at 18:43
Sure, but you have a view controller that presents a webview (or something)? — Chris Droukas, Mar 22 '17 at 18:47
of course WebViewController my present webview i input username and password my app after login on website — Burak Şentürk, Mar 22 '17 at 18:49
In that case, use `UIWebViewDelegate` to invoke native (Swift or Obj-C) functions/methods from your webview. http://stackoverflow.com/a/15541607/1313761 — Chris Droukas, Mar 22 '17 at 18:57

You can use a WKScriptMessage and javascript to make a callback to your viewController and exicute native code.

In your viewController:

//MARK: WKScriptMessageHandler (callback from js in HTML file)
func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage){
    if message.name == "callbackHandler" {
        print(message.body)

        //My function
        if (message.body as AnyObject).contains("myFunctionName"){
            self.playVideo()
        }
    }
}

In your HTML file:

<!-- JS for Native Application Callbacks -->
<script type="text/javascript">
    function callNativeApp () {
        //iOS
        try {
            window.webkit.messageHandlers.callbackHandler.postMessage("myFunctionName");
        } catch(err) {
            console.log('The native context does not exist yet');
        }
    }
</script>
