App Thinning
App Thinning is an iOS and watchOS optimization technique that reduces the size of apps downloaded from the App Store by tailoring app delivery to each user's specific device. It includes features like slicing (delivering only the resources needed for a particular device), on-demand resources (downloading additional content as needed), and bitcode (allowing Apple to re-optimize the app binary). This helps minimize storage usage and download times for users.
Developers should use App Thinning to improve user experience by reducing app download sizes, especially for large apps with many assets or multiple device configurations. It's crucial for apps targeting diverse iOS devices (e.g., different iPhone models or iPads) to avoid bloated installations and comply with App Store guidelines for efficient resource usage. This is particularly beneficial for games, media-rich apps, or apps with internationalization where resources vary by region.
