CAUTION
In Xcode 3, you fixed a broken reference by selecting the file on disk. In Xcode 4, you fix it by selecting the folder
that holds the file.
FIGURE 5.10
You can change the path of a file to fix a missing reference or to substitute one version of a file in one folder with a
different version in another, although there are better ways to manage version control in Xcode.
Working with Groups
Groups are cosmetic, for your convenience. You can use any group structure, nested as deeply as you like. The
default structure with separate class and resource folders is only one of many possible arrangements. You also
may create a separate group for each class or (less usefully) a single group for every file in the project.
Moving groups and files
Files are compiled more or less in descending order through the Navigator. Circular class references are handled
automatically, so there's no significant speed advantage to reordering the groups. But it's sometimes useful to
modify the group order for clarity.
You can drag and drop groups in the Project Navigator, but dropping a group on another group nests it, which
may not be what you want.
