Understanding the Apple Documentation
Accessing the documentation from the web for the first time can feel overwhelming. The organization seems
haphazard, and it's not clear which elements are essential, which are useful, and which are irrelevant. The con-
tents are organized by OS and also by
resource types—
different kinds of information. Confusingly, there's signi-
ficant overlap between the OS X and iOS documentation and also between different versions of each OS.
Comparing iOS and OS X and their different versions
If you access the documentation from the web, the organization online doesn't distinguish between different
versions of iOS and OS X. The iOS and OS X portals always show the most up-to-date content. This can be a
beta version of the OS, which may not be what you want.
Xcode's own documentation viewer, shown in Figure 6.3, makes the differences between OS versions explicit.
Each OS has a separate library header, so you can find the information you need without ambiguity.

Using Xcode's documentation viewer is built into the Organizer section of Xcode, but it can be accessed directly
from the main menu.
