Getting Started

Figure 1.7

At the left of the navigation bar, a separate menu shows files and items that are more loosely related to

the currently selected file.

Using the Assistant

Xcode 3 included a counterpart file selector that switched an editor window between a class

header and its corresponding implementation file. Xcode 4 introduces Assistant, which is

designed to work with a new vertically split double-pane view. When you select a file for edit-

ing, Assistant makes an informed guess about a useful counterpart and displays it automati-

cally, as shown in Figure 1.8. By default, this means that selecting a header displays the

implementation file in the second pane, and vice versa.
