A site with tutorials on Cocoa topics (usually aimed at beginners) and highlights of recent blog posts on Cocoa.

The articles are generally very well-written with good illustrations, and will help novice programmers especially to get a firm footing in Cocoa and Objective-C. By themselves, these tutorials probably won't enable you to create the next "killer app", but will provide a general idea of how some basic tasks work and help you get your feet wet with Objective-C.
