Swift
Swift is Apple's main programming language for creating apps that work on iPhones, iPads, and Mac computers. It was introduced by Apple in 2014 as a more modern and easier-to-use replacement for their older language, Objective-C. Think of Swift as the primary tool that developers use to build any software that runs on Apple devices. It's similar to how architects use specific tools to design buildings - developers use Swift to design and build Apple apps. While other programming languages like Java or Kotlin are used for Android apps, Swift is specifically designed for Apple's ecosystem.
