If you’re a member of Apple’s iOS or Mac developer program, head over to Apple’s Development Videos Site, where Apple has just published the videos of the WWDC 2011 sessions. As last year, the videos are a free download for all registered developers and not only for WWDC attendees.
I am sure this year’s WWDC videos will again turn out to be the best way to learn about all the new technologies Apple will introduce in Lion and iOS 5. Each session is between 45 minutes and one hour long and the presentations are usually top notch. You should watch as many of them as you can.
Keep in mind that the release of the WWDC videos does not mean that we are allowed to talk publicly about the new stuff that Apple introduced at WWDC. Everything that is related to unreleased software (Lion and iOS 5) is still under NDA until the official release.
