How to display a specific ViewController in OneSignal Swift

I do app with OneSignal and Swift 3. I got push. How to display a specific ViewController with WebView in OneSignal when notification is clicked. In push in additional data with field "link" I got link, but can't display this link in my WebView.

I try use global variable tempURL to put url from additional data. But it not work.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    OneSignal.initWithLaunchOptions(launchOptions, appId: "MYID", handleNotificationAction: { (result) in
      let payload = result?.notification.payload
        print("This is Payload \(payload)")
        var fullMessage = payload?.title
        let messageTitle = "OneSignal Example"

        if (result?.action.actionID) != nil {
        let additionalData = payload?.additionalData
        let url = additionalData?["link"] as! String?
        tempURL = url!
        fullMessage =  fullMessage! + "\nPressed ButtonId:\(url)"

        }

        let alertController = UIAlertController(title: messageTitle, message: fullMessage, preferredStyle: .alert)
        let okAction = UIAlertAction(title: "OK", style: .default)
        alertController.addAction(okAction)
        alertController.show(alertController, sender: nil)

     })
   return true
}

Try to show:

func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {

    let aViewController = ViewController()
    aViewController.loadAddressURL(url: tempURL)
    UIApplication.shared.keyWindow?.rootViewController?.present(aViewController, animated: true, completion:nil)

}

I have error:

fatal error: unexpectedly found nil while unwrapping an Optional value

first of all you can't pass data in your way. You should instantiate ViewController with StoryboardID. I explained how to use it with this link.

If you are pretty sure, your additionalData is not nil, you can pass your data with StoryboardID.
