What is language swift all about?

Answer 1

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, Linux, and z/OS. Swift is designed to work with Apple's Cocoa and Cocoa Touchframeworks and the large body of existing Objective-C code written for Apple products. It is built with the open source LLVM compilerframework and has been included in Xcodesince version 6, released in 2014. On Apple platforms, it uses the Objective-C runtime library which allows C, Objective-C, C++ and Swift code to run within one program.
