In an announcement that had the crowd shouting its approval, Craig Federighi, Apple's senior vice president of software engineering, said "We think Swift is the next big programming language. We think Swift should be everywhere and used by everyone. So we're going to do something really big. Today we're announcing that Swift will be open source."
While Apple hoped Swift would make coding easier, faster and more stable while creating results that perform better in the end. it hasn't been without problems and bugs. By open-sourcing it, Apple hopes to find and fix these bugs faster.
"We will be rolling out the compiler and standard libraries for iOS, OSX and Linux. It will all be out there by the end of the year," said Federighi,
"Swift provides a single language to create apps for both OS X and iOS. There are really so many possibilities for you to use these platforms and these tools to create unbelievable apps that will impact health-care, education and really everything in our lives. There's seemingly no limit to what you can do."
He added that Swift will be adding new language features. This won't be at the expense of speed. Federighi said, "Swift was designed from the beginning to be fast. continued to roll out targeted optimizations all year long. Now [in Swift 2.0 the language will include] whole module optimization."
