Apple is planning to introduce an SDK for the Apple TV at WWDC that will enable developers to create television apps, according to BGR.
We have heard from a source that Apple will be introducing a TV SDK at WWDC next week. This would enable third-party developers to create software for Apple's TV products. BGR reported late last month that Apple has plans to demonstrate an all new TV operating system during its WWDC keynote next week.
Daring Fireball's John Gruber also theorized that this might be the case due to the amount of TBA sessions.
Apple is also expected to announce a massive update to its Mac lineup, refreshing 4 out of 5 of its offerings.
