Objective-C(redirected from Obj C)
Objective-CThe first commercial object-oriented version of the C programming language. Objective-C was used to write macOS and iOS (iPhone/iPad) applications prior to Apple's adoption of the Swift language. Objective-C is created in the OpenStep development environment, and applications use the Mac's Cocoa or Cocoa Touch object libraries or the GNUstep library, which is part of many Linux distributions. Windows versions are also available, and numerous hardware platforms are supported under the GNU gcc compiler.
A superset of the C language, most C programs can be compiled with an Objective-C compiler. Objective-C requires a runtime module that is considerably more lightweight than virtual machines used by languages such as Java. Originally developed by the Stepstone Corporation, Objective-C was licensed by NeXT Computer (later acquired by Apple) and made part of its NeXTSTEP/OPENSTEP environment. See Swift, NeXTSTEP, Openstep, GNUstep and object-oriented programming.
