Swift is a programming language developed by Apple in secrecy for four years and released on June 2, 2014, combining the best features of C and Objective-C. It supports modern programming features like closures, generics, and option types while emphasizing safety and type safety. Swift 2.0 was introduced at WWDC 2015, adding built-in API availability checks and earning accolades for its open-source announcement.
