iOS Swift Enums and Structs Enums Enum Members and Raw Values

not getting the turtleSpeed challenge. Is this a system error or a bug?

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

var turtleSpeed = Speed.Slow.rawvalue

// this is giving me an error.

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

var turtleSpeed = Speed.Slow.rawvalue

Instead of assigning turtleSpeed as a variable make it a constant. The rawValue is a constant assigned to enumeration members.

I would rewrite the code as follows using let keyword.

let turtleSpeed = Speed.Slow.rawValue

Hope this helps!

I bet your problem stems from the fact that you're not properly capitalizing the rawValue property of your enum case. Swift is case-sensitive, so you need everything to be properly capitalized. Try it like this:

enum Speed : Int{
    case Slow = 10
    case Medium = 50
    case Fast = 100
}
//Notice the capital "V" in "rawValue"
var turtleSpeed = Speed.Slow.rawValue
