Apple introduced a brand new programming language last year that’s meant to make coding an app for iOS or OS X easier. Starting this month it is also officially open source. Apple is opening up the language through a new website, Swift.org. Developers outside of Apple will now be able to look inside of Swift, contribute to its development, and bring it to new platforms (Apple just added Linux).
While you shouldn’t expect Apple to work on further ports of Swift itself, open sourcing its code means that other developers could choose to bring it to Windows and Android, too. Apple has said that it wants Swift to be one of the core programming languages of the next 20 years, and to truly happen it will need to work with the biggest desktop and mobile platforms.
