What is Objective-C?
Objective-C is an object-oriented programming language closely associated with the development of macOS and iOS and was later acquired by Apple. Until the introduction of Swift, Objective-C was the primary programming language for macOS and iOS applications. Many well-known apps and frameworks were developed in Objective-C, including Core Foundation and Cocoa Touch.
Swift or Objective-C?
Although Swift is now preferred, there are still many existing codebases in Objective-C that need to be maintained and migrated. The Objective-C community remains active, providing support and resources for developers, although many have switched to Swift.
Shortcut Objective-C
Objective-C was long the #1 for macOS and iOS apps and still forms the backbone of many well-known Apple frameworks. Even though Swift has now taken the lead, Objective-C remains relevant - many apps still run on this basis, and the community continues to support them with know-how and resources.
