Greetings,In my application I'm loading a locally stored webPage.html that is being packaged alongside the app inside its bundle.Prior to iOS 13 the application successfully loaded the webPage.html and received further load events triggered by the JavaScript, these pages were loaded using load(request:) on WKWebView.After updating the device to iOS 13 beta 3 (public) I'm getting the following error messages:Received an unexpected URL from the web process: 'file:///var/containers/Bundle/Application/{Application Identifier}/{Application Name}.app/Html/webPage.html' WebPageProxy::Ignoring request to load this main resource because it is outside the sandboxLooking into it I've discovered the loadFileURL(url:, allowingReadAccessTo:) which solved the above issue.However when the HTML page attempts to load any local reference like /nextPage it fails with the following log:Received an unexpected URL from the web process: 'file:///nextPage' WebPageProxy::Ignoring request to load this main resource because it is outside the sandboxThis only occurs on iOS 13 beta 3 (public),This is not reproduceable in simulator. (simulator works out of the box, without any changes)I haven't attempted on the iOS 13 beta 4 (developer) as of yet.
