Apple now sells the Microsoft Xbox Wireless Controller through its online store. The move is likely due to Apple's recent push into the gaming market. Considering the latest OS updates for all Apple devices (e.g., iOS 13, iPadOS, and macOS Catalina) include native support for the Xbox Wireless Controller and Sony's DualShock 4 controller, it makes sense for Apple to offer the controller directly to its user base.
