Apple has announced to developers that the size limit for tvOS app bundles has been significantly increased, with the new maximum size going up to 4GB from the prior 200MB limit. This change will allow developers to include more media content bundled in their app package so that it installs at the same time the user installs the app on their Apple TV, which should minimize the number of games and other apps that need to download additional content when first opened. tvOS apps can also now host up to 20GB of additional content on the App Store using On-Demand Resources.
This is likely to have an impact on users’ Apple TV storage capacities, meaning users with a lot of larger apps and the lower capacity 32GB Apple TV model may find themselves constrained for space as their apps are updated to include media content within the app bundles. The prior 200MB limit kept the apps small and allowed storage on the Apple TV to be optimized by discarding on-demand data from apps when the Apple TV ran low on space; this will not be an option for an app that stores a large amount of media content within the app bundle itself. This could also be a sign that Apple is preparing to release higher-capacity Apple TV models in the near future.
