Pierre Blazquez found on Friday that a code within iOS 7.1 SDK indicates that Siri may be available on the Apple TV soon. 9to5Mac has confirmed that the code exists in iOS 7.1 and iOS 7.1.1’s files.
The file is a supporting property-list resource for Assistant (Apple’s internal name for Siri), containing information about the feature. The UIDeviceFamily array declares what platforms are compatible with the feature.
Apples document in the photo bellow shows ’1′ and ’2′ represent the iPhone/iPod touch and iPad families. The ’3′ represents the Apple TV family.
The Apple TV has been given the ’3′ designation ever since Apple TV became based off iOS. The Lowtide application uses the ’3′ identifier for instance, as do current Apple TV apps.
This isn’t evidence of new hardware and probably won’t be adding Siri to current Apple TV’s since they lack a microphone input. But it is believed that Apple is working on a new Apple TV that will focus on apps and games.
