------------------------------------------------------------

I recently made a simple test using [cordova-plugin-wkwebviewxhrfix|https://github.com/TheMattRay/cordova-plugin-wkwebviewxhrfix.git]
and it seems to work. In addition could some in the community help validate?

+*My tests*+
My ajax requests worked after "cordova plugin add" and stopped working when "cordova plugin
remove". (cordova-plugin-wkwebviewxhrfix)

+*Test calls that I made were from:*+
$.ajax("js/test.json"
and
$.ajax("http://loacalhost: ..
and
$ajax("...Library/NoCloud/test.json" 

*+Using:+*
iOS simulator
cordova -v  7.0.1
jQuery.min.3.1.1

+*See below index.html and config file.*+
{code:xml}
//index.html
<meta http-equiv="Content-Security-Policy" content="default-src * 'unsafe-inline'; style-src
'self' 'unsafe-inline'; media-src *" />

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: cordova-plugin-wkwebview-engine

>              Labels: wkwebview-known-issues
>
> mobile-spec failure in XMLHttpRequest.spec.4 is a known WKWebView issue, where CORS is
now respected and cannot load files from file:// urls, only http*:// urls are allowed.
> With CSP off to rule things out:
> XHR to yourself of course works, but doesn't really make sense for
> real-world use. XHR to a sibling file, parent file, or any child file
> results in the error ""Cross origin requests are only supported for
> HTTP”.
> To illustrate:
> {code}
>   |
> parent.xml
>   |
> www
>   |---- index.html (file currently loaded)
>   |---- sibling.xml
>   |---- child-folder
>   |       |---- child.xml
> {code}
> index.html is the currently loaded file in the WebView. From it, you
> can't load parent.xml, sibling.xml nor child.xml using XHR according
> to my tests.
> The workaround is implementing CB-10109
