From the show notes:
Recorded in front of a live audience in San Francisco, John Gruber is joined by Phil Schiller and Craig Federighi to discuss the news from WWDC: WatchOS 3, MacOS 10.12 Sierra, iOS 10, and more.
I tried to watch the show live, as it was recorded Tuesday night. Unfortunately, the stream kept going down and I ended up having to find a stream on Periscope to see it to the end. But the video and audio quality were piss poor, at best, and I missed a big chunk in the middle while I was searching for a bootleg stream.
Luckily, John Gruber has now published a video of the episode which I’ll be watching later tonight.
