Cant assign the rawValue of 10 to turtleSpeed

I tried following code to assign the rawValue of 10 to turtleSpeed, but I can not find out why this is not the right solution. Any hints?

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

var turtleSpeed = Speed(rawValue: 10)

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

var turtleSpeed = Speed(rawValue: 10)

task 1 states: Create a variable called turtleSpeed and assign it the Raw value of the member Slow.

to access the raw value of an enum member you use the raw value property:

EnumName.memberName.rawValue

so to create a variable called turtleSpeed and assign it the raw value of slow you use:

var turtleSpeed = Speed.Slow.rawValue

Here's how I approached it:

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

Step 1: Create a variable called turtleSpeed

var turtleSpeed

Step 2: Assign the raw value of the member Slow

var turtleSpeed = EnumName.memberName.rawValue

Step 3: Piece it together

var turtleSpeed = Speed.Slow.rawValue
