Cocoa is an object-oriented application environment designed specifically for developing Mac OS X native applications. The Cocoa frameworks support rapid development and high productivity, and include a full-featured set of classes designed to create robust and powerful Mac OS X applications. Cocoa provides developers starting new Mac OS X projects the fastest way to full-featured, extensible, and maintainable implementations. Applications from UNIX and other platforms can also be brought to Mac OS X quickly by using Cocoa to build state-of-the-art Aqua user interfaces while retaining most existing core code.
