Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk-style message passing (messaging) to the C [3] programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system .
Brad J. Cox (May 2, 1944 – January 2, 2021) [1] was an American computer scientist who was known mostly for creating the Objective-C programming language with his business partner Tom Love and for his work in software engineering (specifically software reuse) and software componentry.
The most important usage of PyObjC is enabling programmers to create GUI applications using Cocoa libraries in pure Python. [2] Moreover, as an effect of Objective-C's close relationship with the C programming language (it is a pure superset), developers are also able to incorporate any C-based API by wrapping it with an Objective-C wrapper and then using the wrapped code over the PyObjC bridge.
When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C programming language. [1] It was extended to compile C++ in December of that year. Front ends were later developed for Objective-C, Objective-C++, Fortran, Ada, D, Go and Rust, [6] among others. [7]
Cocoa is Apple's native object-oriented application programming interface (API) for its desktop operating system macOS.. Cocoa consists of the Foundation Kit, Application Kit, and Core Data frameworks, as included by the Cocoa.h header file, and the libraries and frameworks included by those, such as the C standard library and the Objective-C runtime.
GNUstep contains a set of graphical control elements written in the Objective-C programming language. The graphical user interface (GUI) of GNUMail is composed of graphics control elements. GNUMail has to interact with the windowing system, e.g. X11 or Wayland, and its graphical user interface has to be rendered.

Swift and Objective-C code can be used in one program, and by extension, C and C++ also. Beginning in Swift 5.9, C++ code can be used directly from Swift code. [95] In the case of Objective-C, Swift has considerable access to the object model, and can be used to subclass, extend and use Objective-C code to provide protocol support. [96]
