Swift 5 Disable Redirection from WKWebView to different Apps

Question

I have a WKWebView inside my app. The problem is that when for example going on https://stockx.com/de-de and the user has the StockX app, the user is redirected to the app. Is there any way to disable this redirection in genreal for my webView? I couldn't find anything on this... Not too sure if you need code but here is my webView:

lazy var webView: WKWebView = {
    let webConfiguration = WKWebViewConfiguration()
    let webView = WKWebView(frame: .zero, configuration: webConfiguration)
    webView.uiDelegate = self
    webView.translatesAutoresizingMaskIntoConstraints = false
    return webView
}()

Apparently there is this function for an older Swift version:

func webView(webView: WKWebView, decidePolicyForNavigationAction navigationAction: WKNavigationAction, decisionHandler: ((WKNavigationActionPolicy) -> Void)) {
    print("webView:\(webView) decidePolicyForNavigationAction:\(navigationAction) decisionHandler:\(decisionHandler)")

    let app = UIApplication.sharedApplication()
    let url = navigationAction.request.URL
    let myScheme: NSString = "https"
    if (url!.scheme == myScheme) && app.canOpenURL(url!) {
        print("redirect detected..")
        // intercepting redirect, do whatever you want
        app.openURL(url!) // open the original url
        decisionHandler(.Cancel)
        return
    }

    decisionHandler(.Allow)
}

But this is no longer working in Swift 5. Any idea how to to this in Swift 5?

So what is happening here it's web app initializing universal link. What you can theoretically do to block this:

        print("webView:\(webView) decidePolicyForNavigationAction:\(navigationAction) decisionHandler:\(decisionHandler)")

        let app = UIApplication.sharedApplication()
        let url = navigationAction.request.URL
        let myScheme: NSString = "https"
        if (url!.scheme == myScheme) && app.canOpenURL(url!) {
            print("redirect detected..")
            // intercepting redirect, do whatever you want
            app.openURL(url!) // open the original url
            decisionHandler(.Cancel)
            return
        }

        decisionHandler(.Allow)
    }
