To get the most out of this book

Before reading this book, you should already be comfortable with Swift and have a decent understanding. We will not go into any great detail regarding Swift as we will assume that you are already familiar with it. Any new topics will be discussed:

If you do copy and paste code, please understand that this will cause your code to not be formatted and will make it difficult to read. It may also add extra text and/or strange characters that result in errors within your code. As the author of this book, I can advise you that copying and pasting code with which you are unfamiliar is hard and will cause a lot of problems.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
