Summary


In this chapter, we covered control flow and functions in Swift. It is essential to understand the concepts in this chapter before going on. Every application that we write, beyond the simple Hello World applications, will rely very heavily on the control flow statements and functions.

The control flow statements are used to make decisions within our application, and the functions will be used to group our code into the sections that are reusable and organized.
