Apple has posted the 2015 WWDC event online, which you can stream at your leisure. I say "event" because the day included a comedic intro with several celebrities, beautiful product videos -- three for Apple Music alone -- and a musical performance by The Weeknd. The whole thing clocks in at two-and-a-half hours, so set some time aside to watch.
It was an interesting event with lots of good news for developers, like open-source Swift 2, and glimpses at the future of OS X, iOS and watchOS. There were odd moments too, like an apparently nervous Drake and Eddy Cue's Music Hour. Watch now and see for yourself.
