title: Do Prefetch Tags for iOS On-Demand Resources need to be requested?
body: <p>According to Apple's <a href="https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/On_Demand_Resources_Guide/Tagging.html#//apple_ref/doc/uid/TP40015083-CH3-SW2" rel="nofollow noreferrer">documentation</a> about <strong>Prefetched On-Demand</strong> tags:</p>
  <blockquote>
  <p>The resources start downloading after the app is installed. The tags
  will be downloaded in the order in which they are listed in the
  Prefetched tag order group.</p>
  </blockquote>
  <p>Do assets designated with Prefetched Tags need to be explicitly requested via <code>beginAccessingResources</code> on <code>NSBundleResourceRequest</code> (just like regular <strong>Downloaded Only On Demand</strong> tags), or should they automatically download without any explicit code as the docs suggest?</p>
  <p>I've tagged several assets with Prefetched Tags but I'm not seeing them automatically downloaded in Debug builds, but if I explicitly request them, they will be downloaded. (I've not yet tested on TestFlight.)</p>
