  window.webkit.messageHandlers.MobileBridgeBridge.postMessage({
    // ......message body
  })

  # receive message
  let webConfiguration = WKWebViewConfiguration()
  let contentController = WKUserContentController()
  
  contentController.add(self, name: "MobileBridgeNative")
  webConfiguration.userContentController = contentController;
  
  webView = WKWebView(configuration: webConfiguration) // plus any other settings
  
  func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
      if (message.name == "eventHandler"){
          let data = message.body as! NSDictionary
         // use data
      }
