As promised earlier this year, Apple has officially released its Swift programming language to the open source community. Originally unveiled at WWDC 2014, the Swift programming language was intended to provide iOS developers with a simpler and higher-performance alternative to Objective-C, which had been the core development language for the iOS SDK since the debut of the App Store in 2008.
Apple integrated Swift into its set of Xcode development tools and SDKs, and streamlined the process of gradually migrating apps to Swift by allowing Objective-C and Swift code to be mixed seamlessly. By making Swift open source, Apple hopes the programming language will be adopted across a wider range of platforms, including not only mobile apps but also desktop and cloud applications.
