Nativescript + iOS webview + local files - ios

Question

I'm currently working in a simple app, which has a HTML section which uses a webview.
The contents are in an app/www folder, and I access them from a "home.ts" component with something like this in the 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 a few images, some JS and some CSS.
It works fine on Android, but I can't make it work on iOS. Oh, and it works fine on the iOS emulator, but not in an actual device (I currently have a iOS 9 iPod touch for testing these things).
I have the correct keys configured on Info.plist (it works with URLs as https://www.google.com), and I think I'm not doing anything weird.
This is my package.json

It's a known bug for local pages, it's not able to determine what ~ means in terms of filesystem
you need to change the src in your code and figure out what ~refers to.
using :
import * as fs from "tns-core-modules/file-system";
public webViewSRC: string = encodeURI(`${fs.knownFolders.currentApp().path}/www/index.html`);
