Preparing for On-Demand Resources

If you’re using on-demand resources in your iOS 9 app, please note the following as you prepare your app for submission.

Make sure your code checks for on-demand resource asset packs as part of your standard code path and uses NSBundleResourceRequest to manually download the content if it is not present. This is important as there is a known issue that may cause initial and pre-fetch on-demand content to not download automatically.

On-demand resource asset packs that are added or changed as part of an app update are currently inaccessible. Be sure to include new or updated asset packs in your application bundle during your app update submission.

These issues will be resolved in a future iOS update.
