Successful programmers know more than a computer language. They also know how to think about solving problems.

Code Clinic is a series of ten courses where lynda.com authors solve the same problems using different programming languages. Here, Simon Allardice works with Swift.

Simon introduces challenges and then provides an overview of his solutions in Swift. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
