In this chapter, we looked at what programming actually is, why it is useful, and examples of what we use programming for. We discussed what a world without programming would look like and we looked at a short introduction to the Swift programming language. Lastly, we introduced what the reader can expect to learn when reading this book and how this can be used moving further into the world of programming.

In the next chapter, we will go over the practical part of getting the user set up with the right tools in order to begin programming.
