Getting Started

A guided introduction and learning path for developers new to Cocoa.

Cocoa is Apple's name for the collection of frameworks, APIs, and accompanying runtimes that make up the development layer of Mac OS X. By developing with the Cocoa frameworks you will be writing applications the same way that Mac OS X itself is written, with complete access to the full power of the operating system, including the signature Mac look and feel. Cocoa is simply the best way to create native Mac applications.

The Cocoa frameworks are primarily written in Objective-C, and support both 32-bit and 64-bit applications as well as Objective-C 2.0's garbage collection, although there are a few components written in other languages such as C for performance or compatibility reasons, such as Core Foundation. The Cocoa frameworks are completely accessible to Objective-C programs, and can even be accessed using native syntax from AppleScript, Python, and Ruby. Example frameworks included within Cocoa are Foundation, which defines the "nuts and bolts" classes for Objective-C programming, and Application Kit which includes higher-level controls such as windows, buttons, menus, and text fields. Whatever you need to develop, Cocoa contains the frameworks to make development productive and enjoyable. Read More...
