Mitchel Broussard, MacRumors:

Apple has added the Xbox Wireless Controller to Apple.com, although the accessory is currently unavailable to purchase at the time of writing. Apple sells a few different gaming controllers on its website to connect to iOS, iPadOS, and tvOS devices, but as of yet the company has never directly sold Microsoft or Sony’s own gaming controllers.

I’ve been using an MFi controller on my iPad and, I have to say, it makes all the difference in playing Apple Arcade games.
