And more than Swift

But whether you refer to yourself as a software engineer, app developer, or hacker, there is substantially more to the job than writing Swift code inside Xcode. We will also be looking at interacting with bash shells in Terminal, dealing with files in XML format, data returned from the Web in JSON format, a little HTML, and the odd sprinkling of other languages, which may be used outside Xcode to good advantage.

We won't be going into a great amount of depth in these peripheral topics (if they can even be considered peripheral), but we will present what is essentially needed to get the job done, and give the reader an idea of the role they play in the larger picture. The interested reader will find no shortage of books and web resources with which to expand on the information presented here. There are also a number of articles available on the website that accompanies this book: http://grimshaw.de/macOS-book.
