Tue, 19 Jun 2012 18:40:30 PDT Just days after the conclusion of its 2012 Worldwide Developers Conference ( WWDC) in San Francisco, Apple has posted the full set of session videos to its website and iTunes. Access to the videos requires a minimum of a free Registered Apple Developer account. With over 100 sessions available, the videos are a significant resource for those looking to learn more about developing for OS X and iOS. The quick turnaround on posting the videos is helpful for developers who were unable to attend WWDC, especially given that the conference sold out in less than two hours this year. Apple used to charge several hundred dollars for the videos, but ended that practice in 2010 as the company restructured its developer programs to lower the cost of entry and its increasing popularity led to conference sell-outs that prevented some willing developers from attending in person.
