iOS Swift Enums and Structs Enums Enum Members and Raw Values

Enum init broken in Treehouse tester?

Works in playground:

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

var turtleSpeed = Speed(rawValue: 10)

Fails here: expected to be Int but wasn't

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

var turtleSpeed = Speed(rawValue: 10)

You're assigning it to the enum case here rather than the raw value. This is the opposite of what the challenge is asking for.

Here is the correct code:

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

var turtleSpeed = Speed.Slow.rawValue

Hope that helps :)
