Nativescript + iOS webview + local files

I am currently working on a simple application that has an HTML section that uses webview.

The content is in the app / www folder and I am accessing them from the "home.ts" component with something like this in HTML

<GridLayout
    class="main-layout"
    columns="*"
    rows="*"
>
    <WebView
        src="~/www/index.html"
        class="web-view"
        col="0"
        id="wv"
        row="0"
    ></WebView>
</GridLayout>

      

        
        
        
      

    

This file uses multiple images, some JS and some CSS.

It works great on Android, but I cannot get it to work on iOS. Oh, and it works fine on the iOS emulator, but not on the device itself (I currently have an iPod touch for iOS 9 to test these things).

I have the correct keys configured on Info.plist (it works with urls like https://www.google.com ) and I think I'm not doing anything weird.

This is my .json package
