webViewDidFailLoadWithError

webViewDidFail is a delegate method in iOS development, specifically used in the UIWebViewDelegate protocol. This method is called when a web view fails to load a request. It is typically used to handle errors that occur during the loading of web content within an application. The method signature is as follows: func webView(_ webView: UIWebView, didFailLoadWithError error: Error). The parameters include the web view that failed to load the request and the error that occurred. This method allows developers to implement custom error handling logic, such as displaying an alert to the user or attempting to load a different URL. It is important to note that this method is deprecated in iOS 12 and later, and developers are encouraged to use WKWebView and its corresponding delegate methods instead. Despite its deprecation, understanding webViewDidFail is still valuable for maintaining and updating older iOS applications.
