On December 3, 2015, the Swift language, supporting libraries, debugger, and package manager were open-sourced under the Apache 2.0 license with a Runtime Library Exception, and was created to host the project. Swift won first place for Most Loved Programming Language in the Stack Overflow Developer Survey 2015 and second place in 2016. Swift 4.1 was released on March 29, 2018. Swift 4.0 was released on September 19, 2017. Swift 3.0 was released on September 13, 2016. Swift 2.0 was announced at WWDC 2015, and was made available for publishing apps in the App Store on September 21, 2015. ![]() Swift 1.2 was released on April 8, 2015, along with Xcode 6.3. Swift 1.1 was released on October 22, 2014, alongside the launch of Xcode 6.1. Swift reached the 1.0 milestone on September 9, 2014, with the Gold Master of Xcode 6.0 for iOS. The Swift Programming Language, a free 500-page manual, was also released at WWDC, and is available on the Apple Books Store and the official website. Apple planned to make source code converters available if needed for the full release. A beta version of the programming language was released to registered Apple developers at the conference, but the company did not promise that the final version of Swift would be source code compatible with the test version. On June 2, 2014, the Apple Worldwide Developers Conference (WWDC) application became the first publicly released app written with Swift. Swift took language ideas "from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list". History ĭevelopment of Swift started in July 2010 by Chris Lattner, with the eventual collaboration of many other programmers at Apple. Swift 5.5, officially announced by Apple at the 2021 WWDC, significantly expands language support for concurrency and asynchronous code, notably introducing a unique version of the actor model. The introduction of module stability makes it possible to create and share binary frameworks that will work with future releases of Swift. Swift 5.1 builds on the previous version of Swift 5 by extending the stable features of the language to compile-time with the introduction of module stability. Swift 5.1 was officially released in September 2019. Swift 5, released in March 2019, introduced a stable binary interface on Apple platforms, allowing the Swift runtime to be incorporated into Apple operating systems. Code written with previous versions of Swift can be updated using the migration functionality built into Xcode. Swift 4.0, released in 2017, introduced several changes to some built-in classes and structures. In the first quarter of 2018 Swift surpassed Objective-C in measured popularity. Through version 3.0 the syntax of Swift went through significant evolution, with the core team making source stability a focus in later versions. Initially a proprietary language, version 2.2 was made open-source software under the Apache License 2.0 on December 3, 2015, for Apple's platforms and Linux. It underwent an upgrade to version 1.2 during 2014 and a major upgrade to Swift 2 at WWDC 2015. Swift was introduced at Apple's 2014 Worldwide Developers Conference (WWDC). Swift supports the concept of protocol extensibility, an extensibility system that can be applied to types, structs and classes, which Apple promotes as a real change in programming paradigms they term "protocol-oriented programming" (similar to traits and type classes). Īpple intended Swift to support many core concepts associated with Objective-C, notably dynamic dispatch, widespread late binding, extensible programming and similar features, but in a "safer" way, making it easier to catch software bugs Swift has features addressing some common programming errors like null pointer dereferencing and provides syntactic sugar to help avoid the pyramid of doom. On Apple platforms, it uses the Objective-C runtime library, which allows C, Objective-C, C++ and Swift code to run within one program. ![]() It was built with the open source LLVM compiler framework and has been included in Xcode since version 6, released in 2014. Swift works with Apple's Cocoa and Cocoa Touch frameworks, and a key aspect of Swift's design was the ability to interoperate with the huge body of existing Objective-C code developed for Apple products over the previous decades. First released in 2014, Swift was developed as a replacement for Apple's earlier programming language Objective-C, as Objective-C had been largely unchanged since the early 1980s and lacked modern language features. Swift is a high-level general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, D
