How to detect and handle HTTP error codes in UIWebView?

Question

I want to inform user when HTTP error 404 etc is received. How can I detect that? I\'ve already tried to implement

- (void)webView:(UIWebView *)webView didFailL

Heres is my swift 3 version of @AxelGuilmin response:

func webViewDidFinishLoad(_ webView: UIWebView) {

        guard let request = webView.request else { return }

        let cachedUrlResponse = URLCache.shared.cachedResponse(for: request)
        let httpUrlResponse = cachedUrlResponse?.response as? HTTPURLResponse
        if let statusCode = httpUrlResponse?.statusCode {
            if statusCode == 404 {
                // Handling 404 response
            }
        }
    }
