Apple just posted videos for every session at WWDC 2013 so developers who didn’t make it out to California for the conference can still get all the new info on how to prepare their apps for iOS 7 and OS X 10.9 Mavericks.
The WWDC 2013 videos can be streamed from Safari, or you can download them straight to your desktop to watch later. You have to be a registered Apple Developer to view the videos which can be found here once you sign in.
