iOS Functions in Swift Adding Power to Functions Returning Complex Values

Playground think is correct but the EDITOR in treehouse is saying MAKE SURE YOU HAVE RETURNED THE CORRECT VALUES

// Enter your code below func coordinates (for location : String) -> (Double,Double) {

switch location{
case "Eiffel Tower" :(48.8582,2.2945)
case "Great Pyramid" :(29.9792,31.1344)
case "Sydney Opera House" :(33.8587,151.2140)
default :(0,0)
}
return (0,0)

}

var loc = coordinates (for : "Great Pyramid")

functions.swift
// Enter your code below
func coordinates (for location : String) -> (Double,Double)
{

    switch location{
    case "Eiffel Tower" :(48.8582,2.2945)
    case "Great Pyramid" :(29.9792,31.1344)
    case "Sydney Opera House" :(33.8587,151.2140)
    default :(0,0)
    }
    return (0,0)
}

var loc = coordinates (for : "Great Pyramid")

You are missing return after your cases?

func coordinates(for location: String ) -> (Double, Double) {

    switch location {
    case "Eiffel Tower":
        return (48.8582, 2.2945)
    case "Great Pyramid":
        return (29.9792, 31.1344)
    case "Sydney Opera House":
        return (33.8587, 151.2140)
    default:
        return (0,0)
    }
}

thanks it worked
