Objective-C was created in 1983 and evolved through various versions. It was incorporated into Apple products like Mac OS X in 1996 and influenced by Smalltalk and C++. Objective-C 2.0 introduced new features in 2007 and supported the new iPhone platform that year. The language uses square bracket syntax and object oriented features to interface with Cocoa frameworks for building GUI apps on Mac OS X and iOS.
