iOS Swift 2.0 Functions Function Parameters Returning Complex Values

Your function needs to return a tuple containing two Double values.

what I've missed?

functions.swift 
// Enter your code below
func getTowerCoordinates(location:String) ->(location:String,value:String){

    var value:String

    switch location {

    case "Eiffel Tower": value = ("lat:48.85,lon:2.29")
    case "Great Pyramid":value = ("lat:29.97,lon:31,139")
    case "Sydney Opera house":value = ("lat:33.85,lon:151.21")
    default: value = ("0,0")
    }

    return (location,value)
}

jc laurent, the problem is that you're returning a tuple that contains two Strings instead of two Doubles.

Your final code should look like this:

// Enter your code below
func getTowerCoordinates(string: String) -> (Double, Double) {
    switch string {
    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)
    }
}

I had an issue with this problem as well. Everything was correct but it made me add break behind default.

i.e. default: break

Then it worked.
