Apple CEO Steve Jobs, who is on medical leave, won't be doing the keynote. However, a team of Apple executives, led by Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing, will handle the chores. WWDC will offer in-depth sessions on both iPhone OS 3.0 and Mac OS X Snow Leopard, the next major version of the operating system.
“Last June, we gave developers an early look at the powerful new technologies that form the underpinnings of Mac OS X Snow Leopard,†says Bertrand Serlet, Apple’s senior vice president of Software Engineering. “At WWDC, we will be giving our developers a final Developer Preview release so they can see the incredible progress we’ve made on Snow Leopard and work with us as we move toward its final release.â€
Snow Leopard and Mac technical sessions will showcase hundreds of refinements to the operating system and dive deep into its new technologies including a 64-bit architecture, QuickTime X, next-generation multicore and GPU processor support, and new accessibility technologies. iPhone OS 3.0 technical sessions will cover introductory and advanced concepts to help developers get the most out of the iPhone OS 3.0 SDK (software developer kit) and over 1,000 new APIs (application programming interfaces) available for iPhone OS 3.0.
