With recent versions of Xcode, the palettes exercise in Cocoa Programing for Mac OS X has become unusable. These days, when you create a palette project, Xcode creates a palette target and a framework target. Thus, the palette chapter has become a palette/framework chapter.

Here is the updated chapter.

Special thanks to the students at the Cocoa Bootcamp in Rome. As the guinea pigs, they caught several errors and typos.
