Swift. A new language that lets everyone build amazing apps.

Swift is a powerful and intuitive new programming language created by Apple for building iOS and Mac apps. It’s designed to give advanced developers the freedom and capabilities they need to create a new generation of cutting-edge apps. It also opens up a whole new world of possibilities for everyone else. Swift is easy to learn and use — even if you’ve never coded before. So now anyone with an idea can create something incredible.

Developers are already doing
great things with Swift.

From the moment it was introduced, leading developers began embracing Swift. Many companies have already used it to enhance their apps — and some have built new apps entirely in Swift. This fast and efficient language provides real-time feedback and can be seamlessly incorporated into existing Objective-C code.
So not only are developers able to write safer, more reliable code. They’re able to save time and, ultimately, create even richer app experiences.

Better performance
equals better apps.

Swift apps more than live up to the name. For instance, a common search algorithm completes much faster using Swift.

up to 8.4x faster than

Educators are adding Swift
to their curriculum.

Developers aren’t the only ones who’ve noticed the potential of Swift. Some of the top universities and academic institutions have already begun teaching Swift in their computer programming courses, and many will offer free courses on iTunes U soon. Which means the transition from introductory coding to professional programming has never been easier.

Universities that are incorporating Swift into their courses

  • Aberystwyth University
  • California Polytechnic Institute
  • Cuesta College
  • Drexel University
  • Full Sail University
  • Ingésup
  • Northwest Kansas Technical College
  • Plymouth University
  • RMIT University
  • Southern Methodist University
  • Stanford
  • Technical University of Munich
  • Tecnológico de Monterrey
  • University of California, Santa Cruz
  • University of Missouri
