That article is wildly out of date. Notice how it emphatically advises you *not* to compile your applications as 64-bit only, whereas 64-bit only is not only the default nowadays, but is required for all the latest additions Apple has made to the language (including, but not limited to, ARC). It also advises that you should include PPC code in your binaries, which Xcode doesn't even let you *do* anymore.
