Tell us about the problem

I'm trying to access fs.knownFolders.ios.sharedPublic() (or any other known .ios folder, besides Library), so I can use utils.ios.openFile() to open various files (such as pdf, doc..etc) with their default application. The returned fs.Folder is undefined, example:

let sharedPublic: fs.Folder = fs.knownFolders.ios.sharedPublic();
if (isUndefined(sharedPublic)) {
    console.log(`Shared public is undefined!`);
} else {
    console.log(`Shared public: ${sharedPublic.path}`);
}

CONSOLE LOG file:///app/app.component.ts:14:24: Shared public is undefined!

I also attempted to add UIFileSharingEnabled to my Info.plist:

        ...
        <key>UIFileSharingEnabled</key>
	<true/>
</dict>
</plist>
