None of this is going to involve quantum leaps of comprehension. Assuming you understand the concepts summarized in the first few chapters (and we will make that assumption), this book will guide you, step by step, from a position of being able to code adequately to a position of being able to code well.
You will not only write better code, you'll write faster; you will be able to get across new frameworks more quickly; you'll soak up more of what you read on the Web and elsewhere; you'll be able to communicate your thoughts clearly to work colleagues and clients.
And I hope, very much, that you'll continue to feel that feeling of accomplishment you felt the first time you coded up Hello World in whatever language it was at the time. It's that spark that will enable you to code not only well, but brilliantly, if you stick with it.
The next chapter will provide a rapid-but-thorough review of the basics of the language's core features and syntax, assuming a basic familiarity with object-oriented programming, but no advanced knowledge of Swift's previous incarnations. So, without further ado, let us take a rapid tour of the basics of Swift 3.0.
