The iOS 14.5 beta update released a few days ago introduces support for Sony and Microsoft’s latest gaming controllers, allowing iPhones and iPads to be used with the PS5 DualSense controller and the Xbox Series X controller.
An earlier iOS 14 beta indicated that the updated controller’s support is working, but they’re going to live on iOS 14.5. The accompanying tvOS update, tvOS 14.5, is also likely to earn support for the controllers.
The PS5 DualSense and Xbox Series X controller options will be compatible with Apple Arcade games and other iOS games which support controllers. iOS 14.5 is currently limited to developers, but Apple will probably have a public beta coming soon, with the update due in the early spring.
