iOS Swift Enums and Structs Enums Enum Members and Raw Values

The Variable turtleSpeed was expecting a Int but wasn't

In the enum tasks, It asks you to create a var turtleSpeed and assign it the rawValue of the member Slow

var turtleSpeed = Speed(rawValue: 10)

What am I doing wrong here? I understand the error, I am creating a string turtleSpeed how am I supposed to assign it a Int value.

Whats the way around this?

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

var turtleSpeed = Speed(rawValue: 10)

''' <p>var turtleSpeed = Speed(rawValue: 10)</p> ''' is wrong try ''' <p>var turtleSpeed = Speed.Slow.rawValue</p> '''

Ahhh ok I see!!! Thanks,

So in what case do you use the code (rawValue:10) I thought that is used to assign raw values to instances of the enum
