Answer

There are couple of UIWebViewDelegate such as shouldStartLoadWithRequest or webViewDidStartLoad or webViewDidFinishLoad or didFailLoadWithError that help you to accomplish your goal. If you want to perform operation after download then implement this delegate method

public func webViewDidFinishLoad(webView: UIWebView){
 let yourTargetUrl = webView.request?.URL
}
