I use a collection of command line scripts that help me in the production of NSScreencast episodes. Most are written in Ruby, which is a language I know and love, and some are written in bash, which is... a language. I sometimes wonder what these scripts would look like if I were to write them in Swift. So in this new series I'm going to explore rewriting a script that I use to encode videos using Swift. In this episode we'll bring in the excellent Swift Argument Parser library and use it to give us a clean and consistent command line interface to start with.
