Scrape web data with swift

I am trying to grab content from a webpage and everytime I load a webpage into a webview i get an error I have no idea what is going wrong this is the whole of my code

@IBOutlet weak var webView: WKWebView! let url = URL(string: "https://www.google.com")

func applicationDidFinishLaunching(_ aNotification: Notification) {
    // Insert code here to initialize your application
    let request = URLRequest(url: url!)
    webView.load(request)
 webView.evaluateJavaScript("document.getElementsByTagName('html')[0].innerHTML", completionHandler: {(value, error) in
    if value != nil {print("INNER HTML: \(value)")}else{
        print("ERROR: \(error)")}
    })
