With iOS 15, you can more easily bring your controller-based games to iPhone and iPad by using the prebuilt, onscreen touch controls that function as a game controller.
Adding controller support to your game is an easy way to provide a unified experience across iPhone, iPad, Mac, and Apple TV.
The Game Controller framework supports a wide variety of popular controllers, such as the Xbox Series X|S Wireless Controller or the Sony PS5 DualSense Wireless Controller. MacOS Monterey adds support for Adaptive-Sync, which allows you to take advantage of variable refresh rate displays while providing a low-latency, tear-free gaming experience.
