  • Improve application performance using compiler optimizations

This chapter uses the To Do application as an example, but everything covered applies equally to all Cocoa applications (with the exception of the document type information, which is relevant only to multidocument applications).

Configure Application Settings

There are many application specific settings in Project Builder that allow you to control various aspects of an application’s behavior. This section doesn’t exhaustively cover every option (see Project Builder’s online help for more information) but shows you what to do for the settings that are critical to correct application behavior.

Specify a Bundle Identifier

Bundle identifiers are the method Mac OS X uses to uniquely identify applications (and, in fact, any bundle). In one sense, a bundle identifier is very much like the creator code used by Mac OS 9 to identify applications.
