Objective-C
Objective-C is an object-oriented programming language that is widely used for developing applications for Apple's Mac OS X and iOS operating systems. It is a high-level language that provides a simple syntax for writing complex applications, and is known for its dynamic binding and message passing features. Objective-C is an extension of the C programming language and is widely used for building software for the Apple ecosystem, including desktop applications, games, and mobile apps. The language is also used in conjunction with Apple's Cocoa and Cocoa Touch frameworks, which provide a comprehensive set of libraries and tools for developing graphical user interfaces and other complex software. With its strong support for object-oriented programming and its ability to interface with other technologies, Objective-C remains a popular choice for developing software on Apple platforms.
