Apple CEO Steve Jobs will launch next month's Worldwide Developers Conference (WWDC) with a keynote speech.

The Jobs keynote will begin at 10am PDT (6pm BST) on Monday 11 June at San Francisco’s Moscone West.

Apple plans to show developers attending WWDC a feature-complete version of Mac OS X Leopard and give them a beta copy to take home for final testing. Leopard is scheduled to ship in October.

The five-day event, runs from 11 June to 15 June. It will offer over 150 sessions and labs aimed at getting the most out of Leopard.

The conference will also include new content to serve a wide range of developers, including Mac OS X Immersion Monday, designed to quickly get developers who are new to the Mac up to speed; a content and media track that shows developers the best ways to integrate animation, motion graphics, video, rich-media and web-based content into their applications; and dozens of hands-on labs that offer a unique opportunity to work directly with Apple engineers.

Other activities include:

– Presentations from Apple engineers who will provide an in-depth look at Leopard, from its open source foundation to new technologies and innovations like Xcode 3.0, Dashcode, Core Animation, Time Machine, iChat Theater and more;
– Practical hands-on sessions where attendees can learn Apple’s own coding strategies and techniques.
– Topic-focused technology labs with Apple engineers.
– Special events, including the Apple Design Awards.
