iOS Enumerations and Optionals in Swift Introduction to Enumerations Modeling Finite Data

Is the array needed?

In the first video Pasan creates an array called week. I just want to make that I am understanding this correctly? That array is not needed, is it? The rest of the code would work the same without that array?

1 Answer

You are correct: The week array is not needed for the enum. Enums are a kind of custom type you create to assist your programming. It helps you out with syntax highlighting and auto completion. If you take a look at the Swift documentation they have even more functionality and will make your code cleaner.
