“The size limit of an app package submitted through iTunes Connect has increased from 2GB to 4GB, so you can include more media in your submission and provide a more complete, rich user experience upon installation.”
It’s then noted that although the app size is higher, there has been no change to the maximum allowed app size for users to download over a cellular network. This remains at 100MB.
Apple’s 2GB maximum size restriction has been in place since 2008, but developers have often worked around the limit by forcing apps to download further resources after installation. Such measures won’t be as important now. The announcement comes soon after Apple began heavily promoting pay-once games, a type of app which will be most affected by this new alteration.
This change will also affect users. The iPhone 6 and iPhone 6 Plus are available with up to 128GB of internal storage space – a first for the range – but the basic 16GB models are still offered. The iOS operating system takes up around 4GB, leaving users with room for two 4GB apps, if they what to have a little space for anything else. This puts app storage inside an iPhone at an even higher premium than ever before.
