Overview of this book

Over the years, the Mastering Swift book has established itself amongst developers as a popular choice as an in-depth and practical guide to the Swift programming language. The latest edition is fully updated and revised to cover the new version: Swift 5. Inside this book, you'll find the key features of Swift 5 easily explained with complete sets of examples. From the basics of the language to popular features such as concurrency, generics, and memory management, this definitive guide will help you develop your expertise and mastery of the Swift language. Mastering Swift 5, Fifth Edition will give you an in-depth knowledge of some of the most sophisticated elements in Swift development, including protocol extensions, error handling, and closures.

It was a good language to begin programming with, but once I traded in my Commodore Vic-20 for a PCjr (yes, I had a PCjr and I really enjoyed it), I realized that there were other, more advanced languages out there, and I spent a lot of time learning Pascal and C. It wasn't until I started college that I heard the term object-oriented programming language. At that time, object-oriented programming languages were so new that there were no real courses on them, but I was able to experiment a little with C++. After I graduated, I left object-oriented programming behind, and it really wasn't until several years later, when I started to experiment with C++ again, that I really discovered the power and flexibility of object-oriented programming.In this chapter, we will cover the following...
