I am working on a wrapper for WKWebView and want to make sure I handle possible errors.
How can I make WKNavigationDelegate's method
func webView(_: WKWebView, didFail _: WKNavigation!, withError error: Error)
called?
The first thing I tried was to call webView.load(request) with invalid url. As a result, func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error) only was called -- not what I wanted.
The second thing I tried was to call webView.loadHTMLString(html, baseURL: nil) with malformed html. Nevertheless, webView displayed without throwing an error.
You can load a valid URL and stop loading manually as soon as the navigation is committed.
func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {
print("didCommit called - stopping navigation now.")
webView.stopLoading()
}
func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
print("didFail navigation called")
}
