Apple today announced a new programming language called Swift at WWDC, which will replace Objective C as the language developers use for building iOS and OS X apps.
Craig Federighi announced the new language on stage saying, “We’ve used Objective-C for 20 years, and we love it. But we wondered what we could do without the baggage of C.”
Federighi confirmed that Swift code and C can live in the same app together, too, so developers can upgrade their code as they go, rather than replacing it in one go.
