According to Apple, you will be able to use Xbox Series X controllers on iPads, iPhones, Apple TVs, and Macs. Apple’s support page updated with a sentence, stating, “Microsoft and Apple are working together to bring compatibility for the Xbox Series X controller to customers in a future update.”
Apple currently supports Xbox Wireless controller, Xbox Elite Wireless Series 2 controller, Xbox Adaptive controller, and PlayStation DualShock 4 Wireless controller.
Getting Xbox Series X controllers to work on Apple devices will make it easier for Microsoft’s xCloud service–a feature that allows Xbox players to stream games to a screen of their choice–to gain greater traction. While xCloud only works on Android devices currently, Microsoft plans to extend the function to Apple devices in 2021. According to The Verge, Microsoft is working on getting xCloud on Apple products by creating a “direct browser-based solution.” xCloud is integrated with Xbox Game Pass Ultimate, Microsoft’s gaming subscription service, at no extra cost.
