Apple has announced that it is increasing the maximum app size from 2GB to 4GB, thus allowing developers to release apps that are up to 4GB in size. This could pave the way for high-quality game titles that need more space for improved graphical effects and longer playtimes.
The size limit of an app package submitted through iTunes Connect has increased from 2 GB to 4 GB, which means developers can now include more media in their submission and offer a better user experience upon installation.
Apple's new 4GB limit marks the first-ever size increase. The previous size limitation has prevented some games from being available on the App Store, such as Final Fantasy VII, among others. Now, hopefully, we will start seeing more awesome games being released on the iTunes store.
Though the maximum app size has increased to 4GB, Apple is still enforcing the 100MB over-the-air download limit introduced in 2013.
