Apple delivers Xbox and PlayStation 4 controller for iPhone, iPad and Apple TV in the fall. It's a big change from the previously selected MFi Bluetooth controllers that means you can now easily connect any PS4 or Xbox One controller to your device to play games on the go.
I've tried an Xbox One S controller (with Bluetooth support) on my iPad Pro running the new public beta, and I'm convinced this is a big step toward using an iPad as a portable game console.
While all PS4 DualShock 4 controllers support Bluetooth and will work fully on the Xbox page, make sure your controller supports Bluetooth. If it has a headphone jack at the bottom, then you're probably good at walking. You can also check the top of a controller to identify if it has Bluetooth, but most modern Xbox One controllers do.
Pairing a controller is as easy as any other Bluetooth device, and most games that already support MFi controllers immediately detect that the Xbox controller is present and working as you would expect. I've played Real Racing 3, Grand Theft Auto: San Andreas, and Fortnite and I've even managed to stream Xbox games from my console thanks to a third-party app.
Sony's PS4 Remote Play app now supports native DualShock 4 controllers thanks to iOS 13 so you can stream games from your PS4 directly to your iPhone or iPad and use the controller you are more familiar with. This is a good step if you want to play PS4 games remotely, but Microsoft does not yet support this for Xbox games.
With Console Streaming from your Xbox One, you can:
✅ Turn your Xbox One into your own personal console server
✅ Stream your Xbox One library, including Xbox Game Pass, free

Microsoft releases its own Console Streaming Remote Play solution in October. Until then, OneCast, a third-party app priced at $ 11.99, the second best thing and working with the Xbox One controller on iOS 13. You can access your console within your local Wi-Fi, but things like f. eg. The Xbox Home button does not work just yet through OneCast.
This controller support also extends to the Apple TV, allowing you to connect an Xbox or PS4 controller and play back supported games on a larger screen.  I usually play games on the go thanks to the Nintendo Switch, but the smaller 6.2-inch screen, 720p resolution and the overall performance pale compared to most modern iPads, especially the more affordable iPad Pro models. I have not really taken games on the iPad seriously before, as the controller support was missing and titles just did not exist. Like Fortnite on an iPhone X was an exciting look at the future of mobile games, this new controller support in iOS 13 is the next logical step.
It comes at an important time for the gaming industry, as giants like Sony, Microsoft and Google all focus strongly on gaming streaming. Although Microsoft and Google have not committed to xCloud or Stadia running on an iPhone or iPad right now, this additional controller support helps it much easier on the Microsoft site. Google connects its own controller directly to the Stadia instances.
Apple has also aggressively improved its iPad and iPhone chips to better support games, and we are at a turning point where we could begin to see some interesting titles in addition to popular games like Fortnite and PUBG appears on Apple's devices. Apple is not betting on game flow itself yet, but it is tempting game makers in its own Apple Arcade subscription that will offer exclusive titles for iPhone, iPad and Apple TV.
We're heading for a future where you can just bring your phone or tablet with you to play AAA games on the go, whether streamed to the device or running nationally. Performance will always be better in front of your TV with a real console or PC running your games. But if you're on holiday and don't want to have an Xbox or PS4 with you, the iPad is a good alternative.
