On Tuesday October 6th, the third beta version of the upcoming tvOS for developers was released.
Recall that a similar release of the second beta took place less than two weeks ago. tvOS is the operating system for the new TV device Apple TV, which will also be released soon. The tvOS device has support for Siri, universal search, and App Store, thus allowing you to run games on TV.
The update can be installed both wirelessly (on-the-air) itself Apple TV, and through the developer center Apple.
At the moment, almost nothing else is known. But if something interesting appears, we will definitely inform you.
