   > > You should migrate your app to use schemes, which should solve this issue, among other `file://` related issues with the WKWebView. Do note however that switching schemes will cause you lose web storage such as indexedDB or local storage, as the origin of your app will change.
   > > If you must use the `file://` scheme, then I would advise sticking with `cordova-ios@5.1.1` for the time being. You need to use a plugin such as https://github.com/oracle/cordova-plugin-wkwebview-file-xhr, but it currently expects the wkwebview engine to be installed, which is incompatible with cordova-ios@6. I've raised an issue at [oracle/cordova-plugin-wkwebview-file-xhr#55](https://github.com/oracle/cordova-plugin-wkwebview-file-xhr/issues/55) to see if they can update the plugin to support cordova-ios@6.

   > Works for cordova-ios@6.0.0. This was not obvious from the blog release notes nor were these explained on what they do and how to use them (documentation needs updating). They apparently implement an "app" scheme and override the file:// scheme which will be rejected by WKWEBVIEW. I have confirmed that this also works with plugins, file and fileopener2. My app doesn't use inappbrowser so I can't confirm that one.
   
   @eradin when I add those preferences the app loads to a black white screen and does not display my index.html file (which is the homepage of the app) is there anything additional I need to change when I add these config preferences?
