&gt; Just for the sake of mentioning it, this works correctly if you set the
&gt; allowFileAccessFromFileURLs preference in WKPreferences, but there's no
&gt; public API to do so.</span >

Yep, it's there in the source:
<a href="https://github.com/WebKit/webkit/blob/master/Source/WebKit2/UIProcess/API/Cocoa/WKPreferences.mm#L388-L396">https://github.com/WebKit/webkit/blob/master/Source/WebKit2/UIProcess/API/Cocoa/WKPreferences.mm#L388-L396</a>

Are you saying that there is no way to enable that preference when creating a WKWebView?</pre>
