What is Objective-C?

Objective-C is the original language for iOS and macOS development, widely used before Swift's introduction in 2014. It is a superset of C with Smalltalk-style message passing and object-oriented features. Many older iOS codebases and some Apple frameworks are still written in Objective-C, and it can be used alongside Swift in the same project.
