Problems rendering HTML for iOS physical device when updating to WKWebView

Question

When I'm attempting to render HTML in a WKWebView using a custom renderer in iOS, the CSS and images aren't rendered when I use;

public void LoadUrl(string url)
{
var uri = new Uri(url);
var safeHostUri = new Uri($"{uri.Scheme}://{uri.Authority}", UriKind.Absolute);
var safeRelativeUri = new Uri($"{uri.PathAndQuery}{uri.Fragment}", UriKind.Relative);
LoadRequest(new NSUrlRequest(new Uri(safeHostUri, safeRelativeUri)));
}

or;

public void LoadUrl(string url)
 {
 var stringHtml = File.ReadAllText(url, Encoding.UTF8);
 var baseUrl = Path.GetDirectoryName(url);
LoadHtmlString(stringHtml, baseUrl == null ? new NSUrl(NSBundle.MainBundle.BundlePath, true) : new NSUrl(baseUrl, true));
 }

There is no problem in Android or in iOS emulators. Any help is greatly appreciated!

Welcome to Microsoft Q&A!

Try to use WKWebView.LoadFileUrl instead of LoadHtmlString() to access local html file.
