Apple publishes a series of video clips made during the WWDC 2012 sessions

  To help developers who didn't make it to WWDC 2012 to benefit from everything that was discussed during this event, the Apple company published, in the portal dedicated to developers on its website, 113 video clips with the sessions that the company's engineers held during the WWDC. There, developers have at their disposal a lot of information about the ways in which they can improve the application development process, or the ways in which they can make better performing, more attractive applications, applications that will immediately pass through the filter of the company from Cupertino.

  If you are an iOS app developer, then you can find it here the entire list of videos.
