Xcode
Xcode is Apple's premiere development environment for Mac OS X. In addition to being packaged on the DVD with every copy of Mac OS X, the latest Xcode developer release is always available for free to ADC members and includes all the tools you need to create, debug, and optimize your applications. At the heart of the Xcode tools package is the Xcode IDE, a graphical workbench that tightly integrates a professional text editor, a robust build system, a debugger, and the powerful GCC compiler capable of targeting Intel and PowerPC regardless of host platform. Xcode is both easy to use, and yet powerful enough to build the largest Mac OS X applications. The complete Mac OS X developer tools chain is distributed as part of Xcode; these tools include Interface Builder, Instruments, Dashcode, the WebObjects framework, and the complete reference documentation, to name just a few.
