iOS Swift Enums and Structs Enums What is an Enum?

"What is an enum?" Help on Challenge

Hello,

I'm having a bit of trouble with a very simple challenge. Here:

https://teamtreehouse.com/library/swift-enums-and-structs/enums/what-is-an-enum-2

I'm unable to get my code to validate. Following the exact example in the video (below) doesn't work.

// enum Speed { case: Slow, case: Medium, case: Fast}

Some other things I've tried:

// enum Speed { case: "Slow", case: "Medium", case: "Fast"}

// enum Speed : Int { case Slow = 10 case Medium = 50 case Fast = 100 }

I'm sure it's something simple, but I'd appreciate some guidance. Thank you.

Hi Steven,

Try:

enum Speed { case Slow
case Medium 
case Fast}

or:

enum Speed { case Slow, Medium, Fast}

I hope that helps!

Steve.

You don't need the colons after the case keyword. If you separate each case with a comma, you only need to declare case once, too.
