Apple Updates Official WWDC App With New Look, Apple TV Compatibility
A tvOS version of this app is now available, so you can stream and download videos from WWDC 2016 and previous conferences on Apple TV. This update supports live streaming on iOS and tvOS. It also supports multitasking on iOS 9 on iPad.The WWDC app is designed to be used by both conference attendees and developers who were not able to obtain tickets for the event. In addition to providing on-site tools for viewing start times for labs, sessions, and events, the app also offers the ability to watch live streaming sessions with Apple engineers.
With the new tvOS version of the WWDC app, developers who are not attending the San Francisco conference will be able to virtually attend sessions through their television screens.
Apple has also released a schedule of sessions that will take place during the conference, many with humorous names to conceal information that won't be available until iOS 10 and OS X 10.12 are unveiled at the keynote event.
The Worldwide Developers Conference starts on June 13 with a keynote that will take place at 10:00 a.m. at the Bill Graham Civic Auditorium in San Francisco. Apple will likely live stream the keynote on both its website and on the Apple TV, and MacRumors will also provide live coverage on MacRumors.com and through the MacRumorsLive Twitter account.
Apple's WWDC app can be downloaded from the App Store for free. [Direct Link]
