Just for the record, this question appears to have been asked on and linked from the Apple Developer Forums. The official response from Apple is that the HTML5 Application Cache functionality is not available in WKWebView:

The offline application cache is not enabled in WKWebView. Feel free to request that it be made available via https://bugreport.apple.com.
