Chapter 15. Development Tools > The Developer Folder

15.2. The Developer Folder

The /Developer folder contains the following subfolders:


Aqua applications for development, as detailed further in the next section.


This folder holds an immense amount of system documentation in HTML and PDF format, covering the entirety of Mac OS X from a developer's point of view. Topics range from general descriptions of system functionality, to highly specific reference manuals, to the Cocoa and Carbon programming APIs. For more about the documentation that the Developer Tools offer, see Section 15.4.1.

All the documentation found in this folder also exists on Apple's developer web site, http://developer.apple.com.


The /Examples folder contains a wide variety of application project folders, organized by category. Some are .pbproj files and related Aqua interface and localization resources all ready for opening in Project Builder, while others are simple shell scripts or AppleScripts that demonstrate various concepts.

The /Examples/Web Services folder, for example, contains a source to an Aqua application called XMethodsInspector, a couple of AppleScripts (embedded in shell scripts), and a couple of C++ source files. All show different ways of invoking SOAP and XML-RPC web services from your software.


This folder contains FlatCarbon flat header files, which help developers port applications from Mac OS 9 (which had no concept of Frameworks—see Section 15.7.1, later in this chapter, for the difference). The FlatHeaderConversion folder holds tops and perl scripts to help you convert existing legacy source files' header invocations into Mac OS X-style #include directives. Either of these methods will help you migrate older Macintosh codebases to Mac OS X, but the latter method results in code that compiles faster.


Headers and other resources used by Project Builder's Cocoa-Java bridge (see the Java entry in Section 15.5).


Makefiles that Project Builder transparently uses when building applications. Generally speaking, you can leave these be.


Interface Builder (described later in this chapter in Section 15.6) uses palettes to hold the basic elements of Aqua applications' interfaces: windows, controls, and views. When designing interfaces through Interface Builder, drag these controls off the available palettes and into the interface that you're designing.

This folder contains extra palettes beyond those built into Interface Builder.

ProjectBuilder Extras

Extra templates, plug-ins, and examples for Project Builder (see Section 15.4).


Command-line tools from Apple, specifically useful for Darwin development or working with HFS+ filesystems. Chapter 25 covers them all in detail.
