Apple has posted the first set of scheduled sessions and labs for this year’s WWDC here: Worldwide Developers Conference 2009 – Sessions & Labs.

Off the top of my head I think I will be keeping an eye on:

• Advanced Debugging

• Cocoa Tips and Tricks

• Concurrent Programming in Cocoa

• Effective iPhone App Architecture

• Embedding Maps in iPhone Applications

• Performance Tuning with Shark on Mac and iPhone

• User Interface Design for iPhone Apps

Which ones do you have your eyes on?
