Great book so far - but Chapter 4 has me stumped. I am running Leopard, and won’t be upgrading in the near future.
Does Chapter 4 - Classes and Objects - require Snow Leopard? I create an Application -> Cocoa Application (no checkboxes that I can see), and I don’t get a HelloWorldAppDelegate class created.
Also, the heavy lines across top and bottom of pages uses a lot of ink when printing out the pdf :) - I’m sure it will look wonderful in the book, but I like to print out my pdfs so that I can scribble all over them.
