Cocoa

Cocoa is an application environment for both the Mac OS X operating system and iPhone OS, the operating system used on multi-touch devices such as iPhone and iPod touch. It consists of a suite of object-oriented software libraries, a runtime, and an integrated development environment.

This chapter expands on this definition, describing the purpose, capabilities, and components of Cocoa on both platforms. Reading this functional description of Cocoa is an essential first step toward understanding Cocoa as a developer.
