Unable to load a local URL or html file in Corodva iOS with inAppBrowser

Problem

What is expected to happen?

What does actually happen?

I have recently upgraded to Cordova InAppBrowser plugin to 3.2.0 which uses wkwebview to render HTML content. I have always been able to load local HTML file by using the following the code:

 cordova.InAppBrowser.open(
          'cdvfile://localhost/bundle/www/assets/index.html',
          '_blank',
        );

However, wkwebview doesn't support 'cdvfile' so I tried using the relative file as below

 cordova.InAppBrowser.open(
          'assets/index.html',
          '_blank',
        );

This approach is not working either. The inAppBrowser opens and shows HTML Error 403: forbidden. After I close the browser, all the local files like IMG becomes unavailable and browser console [Error] Failed to load resource: the server responded with a status of 403 (Forbidden). I don't understand why closing browser cause other local files become accessible.

I have the same issue. Using "cdvile" scheme gives me an "unsupported URL" error, while using the "file" scheme gives me the following error:

webView:didFailProvisionalNavigation - 1: The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 1.)

I opened a PullRequest to fix opening files with the "file" scheme with WKWebView:

#693

Since I don't want to use a fork in my project, for now I'll use a workaround to avoid loading local files in InAppBrowser in my app, I hope this is fixed soon :)
