With the recent release of iOS 9.0.2, Apple has finally resolved a bug that prevented developers from taking advantage of an iOS 9 feature called App Thinning. Though it hasn’t gotten a lot of press, App Thinning is a great new feature that allows developers to roll out much smaller app payloads than would ordinarily be required. And especially with Apple still selling iPhones with just 16GB of storage, anything developers can do to keep app sizes as small as possible is more than welcome.
If you’re not at all familiar with App Thinning, the way it works is as simple as it is clever. As it stands today, when developers release an app onto the App Store, the binary includes a whole lot of superfluous code to accommodate a wide range of devices, from new iPhone 6s models to 32-bit iPhone 5 devices and more.
