Once again, Stanford University has released a great iOS development course on iTunes University completely for free.
This time, the course teaches the basics of Apple’s new programming language [Swift] and presents an incredible opportunity if you are still coding everything with Objective-C.
The course, titled Developing iOS Apps with Swift, can be accessed through this link of iTunes U. It is currently happening in Stanford, and they have already uploaded the three first classes with their respective presentations. As in previous courses, the teacher [that you may already know] is Paul Hegarty—a good friend of Steve Jobs.
