How return string values?

Hi , I stuck on this code challenge :

import UIKit

enum Speed {
    case Slow, Medium, Fast
}

func printSpeed (speed: Speed) -> String  {
    switch speed {
    case .Slow :
        println("Slow")
    case .Medium:
        println("Medium")
    case .Fast:
        println("Fast")
    default:
        return "Unknown"
    }
    return "How return value???"
}

to return a value you just use the return keyword.

dont use println, use return in the cases:

enum Speed {
    case Slow, Medium, Fast
}

func printSpeed (speed: Speed) -> String  {
    switch speed {
    case .Slow :
        return "Slow"
    case .Medium:
        return "Medium"
    case .Fast:
        return "Fast"
    default:
        return "Unknown"
    }
}
