A code found in iOS 7.1.1 and iOS 7.1 SDK hints that Siri is coming to Apple TV.
A recent report from 9to5Mac has some hints that Apple is actually working on a new input method in the form of Siri for its upcoming version of Apple TV. Pierre Blazquez was the man who first found some code in the iOS 7.1 and iOS 7.1.1 SDK files which hinted that Siri was coming to Apple TV.
Apple internally termed Siri "Assistant". And there is a file found in iOS 7.1.1 SDK code that supports property-list resources for the Assistant feature. And the UI Device Family array present in the string of Assistant contains three items (1, 2, 3) that are compatible with the feature.
If we look into Apple’s documentation, the integers ’1′ and ’2′ shows iPhone/iPod touch and iPad families while ’3′ represents the Apple TV family. Apple is using ’3′ identifier for Apple TV family ever since the launch of Apple TV with iOS.
And this particular reference code is found in both iOS 7.1.1 and iOS 7.1 codes. However, this reference code is not found in iOS 7.0.6. Previously, some references had already been found in iOS code that point toward a new Apple TV. And this current finding does not prove that a new Apple TV hardware is coming.
However, it is obvious that the current Apple TV family will not be able to use Siri since a microphone input is not there. Hence, it seems that Apple will not bring Siri to the current generation of Apple TV.
