What do i need to add to this code after getting:The variable 'turtleSpeed' was expected to be of type 'Int'?

Error: Bummer! The variable 'turtleSpeed' was expected to be of type 'Int', but it wasn't.

Original task: Create a variable called turtleSpeed and assign it the Raw value of the member Slow.

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

var turtleSpeed = Speed(rawValue: 10)

The value you've assigned turtleSpeed to is technically equal to the raw value of the member Slow, but not assigned to the raw value of the member Slow. For example, if you changed Slow to equal a different value (say 25), then turtleSpeed and Slow would hold different values. To access the raw value of a member you want to use the following syntax:

enumName.memberName.rawValue
