À propos de Objective-C
Objective-C is an object-oriented programming language, designed by Tom Love and Brad Cow in the early 1980s.
It is a superset of C and was designed to add object-oriented programming features to C. This makes it possible to compile C programs with an Objective-C compiler. The distinguishing feature of Objective-C is that it is a compiled language with a dynamic runtime. It is used in Apple’s macOS and iOS and their respective application programming interfaces (APIs): Cocoa and Cocoa Touch.
However, it can also be used to develop applications on Linux and Windows, among other systems.
