Swift
Swift is Apple's main programming language for creating iPhone, iPad, and Mac applications. Think of it as the primary tool that developers use to build apps for Apple devices. It was introduced by Apple in 2014 as a more modern and user-friendly replacement for their older language, Objective-C. When you see Swift mentioned in a resume, it typically means the candidate has experience creating iOS mobile apps or other Apple platform applications. This is different from other mobile development approaches like using Java (for Android) or React Native (for cross-platform development).
