HomePod and Apple TV
While even registered developers can’t get their hands on the iOS 13 beta for the HomePod yet, Apple is teasing the new features in the Home app in beta 2 on the iPhone, which also implies that it will provide tighter integration between Apple’s in-home devices — not only the HomePod, but also the Apple TV.
Specifically, new screens appear in the Home app showing setup options for multi-user features on the HomePod and profiles on the Apple TV. It appears that the latter will let you more easily add your identity to Apple’s set-top box for Family Sharing simply by transferring your sign-on credentials directly your iPhone.
