What is Objective C?

Objective C is a programming language that was developed in the early 1980s and has historically been used to create software and applications for Apple’s macOS and iOS operating systems. It was the primary programming language used for macOS and iOS development before the introduction of Swift, which is now the preferred language for developing applications on Apple platforms.

Objective C is an object-oriented programming language, which means it revolves around the concept of objects, encapsulation, and inheritance. It extends the C programming language with object-oriented features, making it possible to write programs that are modular, organized, and easier to maintain.

One of the notable aspects of Objective C is its dynamic runtime environment. This means that much of the behavior of the program is determined at runtime, allowing for features like message passing to objects, which enables the ability to add or modify methods during runtime.

While Swift has largely replaced Objective C as the primary programming language for Apple development due to its modern syntax, performance improvements, and safety features, Objective C code still exists in many legacy applications and libraries. Understanding Objective C can be valuable for developers maintaining or working with older codebases.
