Build Twitch app for Apple TV as well
There currently is no official Twitch app for Apple TV. Since you already build for iOS and iPadOS, there should be high codebase overlap with an Apple TV application.
As a Twitch viewer, I currently need to keep another Apple device open and AirPlaying to the Apple TV. If I move out of range, the stream will drop and needs to be set up again on return. I'd like to let my TV keep running sometimes, just like I could if I was watching cable - no awkward handovers between people to keep the TV running.
If an official Twitch app is out of scope, blessing one of the various 3rd party apps ("Twitchy", "Game Theater for Twitch", "Player2 for Twitch", etc) would be handy so fans would know which one to get/could expect to work well.
Apple TV now has its own Twitch app!
