Removing WebView from View Controller

Question

I have a tableView which launches a URL after the cell was pressed. I am creating webView for it:

var webView = UIWebView(frame: self.view.bounds)
webView.scalesPageToFit = true
view.addSubview(webView)
let request = URLRequest(url: catPictureURL!)
webView.loadRequest(request)
webViewDidStartLoad(webView)

And I have a function to create a close button in it:

func webViewDidStartLoad(_ webView: UIWebView){
    print("JUHUUU")
    var subView = UIView()
    subView.frame.size.height = 10
    subView.frame.size.width = 10
    subView.frame =  CGRect(x: 0, y: 50, width: 100 , height: 100)
    let button = UIButton(type: .system)
    button.frame = CGRect(x: 0, y: 50, width: 100, height: 100)
    button.backgroundColor = UIColor.red
    button.setTitle("CANCEL", for: [])
    button.addTarget(self, action: #selector(webView.removeFromSuperview), for: UIControlEvents.touchUpInside)
    self.view.addSubview(button)
    webView.addSubview(subView)
    //subView.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Done, target: self, action: "dismiss")
}

I have tried in button.addTarget to close the webView and show previous screen, but the

action: #selector(webView.removeFromSuperview)

is removing rootView - not the webView (which is causing crashes). I don't really know how to get webView closed. PS. I have also tried doing #selector("dismiss") and preparing a function with self.dismiss but the result is the same.
