my code works its still saying i need to return a tuple containing two double values

func getTowerCoordinates(towerCoordinates: String) -> (lon: Double, lat: Double){

switch towerCoordinates {
    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)

}

}

getTowerCoordinates("Eiffel Tower")

// error still comes back as saying i need to return a tuple containing two double values

functions.swift 
// Enter your code below

func getTowerCoordinates(towerCoordinates: String) -> (lon: Double, lat: Double){


    switch towerCoordinates {
        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)

    }
}

getTowerCoordinates("Eiffel Tower")

Hey Tahire,

You will soon notice that the challenges are very specific and very picky. While your code may be syntactically correct, it is not exactly what the challenge asks for. You overlooked the one line in the instructions that says, "Note: You do not have to name the return values".

So, if you delete those, you're code will pass.

func getTowerCoordinates(towerCoordinates: String) -> (Double, Double) {

Keep Coding! :)

:dizzy:
