Being aware of the available types in Swift, knowing their similarities, and, more importantly, their differences will help you make better decisions about the way you write your code. The preceding segments have listed several properties of value types and references types. More specifically, you learned a lot about classes, structs, and enums. Closures are also a reference type because they get passed around by their location in memory rather than their value, but there isn't much else to say about them in this context.
