You can’t do much in Xcode without
a project. From the Project Assistant
window, create a new Cocoa documentbased
application named Hello World.
You will be prompted to give the project
a name and a location, as shown in
Figure 25-6. I’ve created a ~/Projects
folder in my home folder, adjacent my
~/Documents folder. I like to subdivide my
Projects folder into general categories,
but you can adapt this exercise to your
own work style.
Xcode’s project window is split vertically
into two views. On the left is the
Groups & Files sidebar, which organizes
your project in a logical, hierarchical
way. On the right is a details view that
gives you more information on whatever
is selected in the sidebar. While it’s
not immediately obvious at first, the right pane is actually further split horizontally. Centered at
the bottom of the view is a small dot. Grabbing the dot with your cursor and dragging reveals
the editor view, as shown in Figure 25-7. You can also reveal the editor by selecting a source code
file in the sidebar, or by clicking the editor toolbar item.

Your new project already has a lot of content in its sidebar. These are Xcode’s smart groups.
Like iTunes, some of these are functional and built-in, while others simply serve to demonstrate
the kinds of smart groups you can create yourself. Any of the preset smart groups can be toggled
by right- or Cmd+clicking the sidebar to bring up its contextual menu, and then selecting
Preferences.
