So, when I say “a specific set of related, discrete values.” What do I mean? Some commons examples are cardinal directions, colors, or card suits. State machines, like a traffic light, are also a great use case.

String Raw Values

Let’s set up one more Enumeration! This one will be for seasons

enum Season

CaseIterable

Sometimes you might want to do something like figure out how many cases an enumeration has, or iterate through those cases and do something with each of them. You can absolutely do that, you just need to make your enumeration conform to the CaseIterable protocol.
