Description

This course introduces Apple's Swift programming language in considerable technical depth, focusing on those parts of the language that you will find new or unfamiliar. Swift is Apple's preferred programming language, and is a vastly better alternative to Objective-C. Learning it is an essential first step to working effectively on the Apple platform. This course is geared to working programmers---prior experience with an OO language is required. You don't need to know anything about the Apple ecosystem, however: this is a language course, not an iOS or OSX programming course. This course covers the most recent version of Swift (2.0).
