I get an error saying it was expecting an Int but when I put it into xcode it works fine

I don't see where the error is in the code as it works in xcode without any errors

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

var turtleSpeed = Speed(rawValue: 10)

They are just looking for you to access the raw value via this format:

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

var turtleSpeed = Speed.Slow.rawValue
