title: App thinning for custom assets
body: <p>I'm writing a game and i'd love to have multiple asset packages (these are .dat files) for different iOS devices (768p iPad, 1536p iPad, 640p iPhone, 750p iPhones, 1080p iPhones).</p>
  
  <p>Is achievable via App Thinning feature ?</p>
  
  <p>I know unity allows this somehow

  <p>I'm using Xamarin, but if its achievable via some command line tools of XCode - thats okay.</p>
