Swift is a compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program. A second free implementation of Swift targets Microsoft's Common Language Infrastructure (a.k.a. .NET) and the Java/Android platform.

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.
