iOS 12 vs iOS 11: What’s New in iOS 12.4.1

Use Siri to Play On Your Apple TV + AirPlay Upgrades

With Siri on your iPhone or iPad you can now control your Apple TV. This isn't total control, but you can start the process easily enough. 

Simply start Siri, or say "Hey Siri", and then "Play movie title on my TV".

We expect that you will need to be specific if you have multiple Apple TVs in your house, but this is a handy way to start a program even if you are in the kitchen and your Apple TV remote is across the room. You can ask Siri to play any video, show, movie, sports event or channel that you have access to, and it should start streaming on your Apple TV. 

You also get AirPlay upgrades with iOS 12.2 that make it easier to use. 

• Dedicated TV controls in Control Center and on the Lock Screen give you quick access to TV controls
• AirPlay multitasking for video allows you to browse other apps, as well as play other short form audio and video files locally on your device without interrupting AirPlay
• AirPlay destinations are now grouped by content type making it faster for you to find what device you want to play to
