Apple’s Siri, the virtual personal assistant that’s currently available in the company’s mobile product line, could be making its way to the Apple TV set-top box, if a newly discovered code string is to be believed. An entry in the iOS 7.1 software development kit mentions Siri support for the Apple TV, 9to5Mac is reporting after confirming its existence in the code. Apple did its best to hide the feature, calling Siri “Assistant” in its code and using integer value “3” to describe Apple TV.
