Apple has posted information to its website detailing which sessions it will offer developers at its upcoming WWDC (Worldwide Developers Conference). The conference, which will obviously focus on Mac OS X Leopard, takes place 11-15 June in San Francisco.

"There's no better time to attend WWDC," Ron Okamoto, Apple's vice president of Worldwide Developer Relations, told PC Advisor's sister title Macworld. "Mac, iPod and Apple TV offer software, hardware and content developers an unrivalled opportunity for innovation."

One popular Apple product not mentioned is the iPhone. Okamoto said that the iPhone would not be released until June and Apple did not want comment further on the product until then.

Apple will help developers get the most out of Leopard with more than 100 sessions and labs. As with past developer conferences the sessions are presented by the Apple engineers that work on the technologies, so developers get first-hand experience in making the technology work with their applications.

The six technical tracks at this year's WWDC are: Leopard Innovations, Mac OS X Essentials, Developer Tools, Information Technologies, Graphics & Imaging and Content & Media.

In 2006 Apple attracted over 4,000 developers to its conference, which led to some innovative products being released - a trend the company expects to continue in 2007.

"The volume and quality of products from our developers has been inspiring," said Okamoto. "It's coming from both camps - small developers and the more established developers that have been with the Mac for a long time. We expect to see much more of that in 2007."
