ReplayKit

Apple's ReplayKit was introduced at last year's WWDC as a tool to record video game play on both the iPhone and iPad. Considering the popularity of video game streaming on sites like Twitch and YouTube, it is a welcome addition.

Apple is aiming to make gaming even more fun on the iPhone and iPad by introducing a few new tools for game developers to use in iOS 9.0. GameplayKit gives developers access to common gameplay mechanics so they can concentrate on other features, and Model I/O helps generate 3D model texture data.
