Apple Executives to Showcase Mac OS X Leopard and OS X iPhone Development Platforms at WWDC 2008 Keynote

CUPERTINO, California-May 13, 2008-Apple® today announced that a team of Apple executives, led by CEO Steve Jobs, will kick off the company's annual Worldwide Developers Conference (WWDC) with a keynote address beginning at 10:00 a.m. on Monday, June 9, 2008 at San Francisco's Moscone West. This year's WWDC will showcase two revolutionary development platforms, the ground-breaking innovations of OS X Leopard® and OS X iPhone™, the world's most advanced mobile operating system.

The five-day WWDC event, which runs from June 9 to June 13, will feature the first ever iPhone track for mobile developers with in-depth sessions and hands-on labs to fully explore the capabilities of the OS X iPhone 2.0 software, including the iPhone SDK and the App Store, a breakthrough way for developers to wirelessly deliver their applications to iPhone and iPod® touch users.

The iPhone track will also enable mobile developers to work side by side with Apple engineers to create amazing applications that leverage iPhone's revolutionary Multi-Touch™ user interface, animation technology, rich set of APIs, including programming interfaces for Core OS, Core Services, Media and Cocoa® Touch technologies, built-in three axis accelerometer and geographical location technology to deliver truly innovative mobile applications.

This year's Mac® track will give newcomers and seasoned veterans alike the technical foundation and techniques needed to develop world-class OS X Leopard applications with sessions that discuss every level of the system, including interface design and implementation, application frameworks, security, localization and networking.

WWDC 2008 will offer over 150 information-rich sessions and labs where Apple engineers will go in-depth on the innovative technologies that power OS X iPhone and OS X Leopard. Developers can bring code to the labs and work one-to-one with Apple engineers, applying development methods and best-practices gained from sessions to enhance their applications.

Other activities at Apple's WWDC 2008 include:

* presentation sessions led by engineers that provide an in-depth look at OS X iPhone, OS X Leopard and innovative tools and technologies such as the iPhone SDK, Cocoa Touch, Interface Builder, Xcode® and more;
* practical hands-on sessions where attendees can learn Apple's own coding strategies and techniques;
* technology labs where attendees can work one-to-one with Apple engineers; and
* special events, including the Welcome Reception, Apple Design Awards, Lunchtime Speakers and Stump the Experts.
