I am getting an error message that says there is an int expected with the variable I am creating in the challenge.

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

let turtleSpeed = Speed.Slow

wich challenge is this? is it asking you to call slow? if so you for got to call it after you defined it:

if so try:

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

let turtleSpeed = Speed.Slow

The variable turtleSpeed is essentially needs to be assigned to the number 10. The member 'Slow' in the Speed enum has a member value of 10. You wrote Speed.Slow but since the variable is an instance of the Speed struct's member Slow which has a value of 10, 'Speed.Slow' only references the enum Speed's member with a name called Slow. However Slow is assigned to an Int value in the enum, which needs to be referenced by using 'rawValue' to refer to the number 10.

enum Speed: Int {
    case Slow = 10
    case Medium = 50
    case Fast = 100
var turtleSpeed = Speed.Slow.rawValue

oh never mind hahahaKyle got it
