In June 2014, Apple introduced Swift, its new programming language that the company has been working on since 2010, and more complete than Objective-C. During the opening keynote of the WWDC 2015 last night, Craig Federighi, the senior vice president of software engineering at Apple, announced the launch of Swift 2 for developers.
This first major update to the programming language developed by the Cupertino company brings dozens of new features, which you can find (in English) on the image above taken from the conference. Regarding performance, Apple ensures that Swift 2 is 6 to 7 times faster than the first version, just that!
Also, be aware that Swift 2 is open source or “open source code”, for anglophobes. On its developer blog, Apple explains that publishers will be able to develop programs for OS X, iOS and Linux at first. Good news to accelerate the development of Swift and its adoption rate.
