After a slight delay in rolling out the feature, Apple announced today that App Thinning has been added to iOS with version iOS 9.0.2.
Originally announced at WWDC, the company was forced to delay the release of this feature late last month after an unspecified issue related to backing up on iCloud.
App Thinning allows developers to upload device specific executables to the App Store. So, instead of downloading a file that contains assets for devices they don’t own, an iPhone 4 owner, for example, can get one executable that contains only the things their smartphone needs to run the app in question. This helps reduce the file size of apps, allowing those with older Apple smartphones and tablets to better manage their device’s storage.
