Im confused where I'm going wrong

i can't seem to grasp where i have gone wrong.

functions.swift
func coordinates(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)
    }

}

Hi Graeme,

in the challenge is states to Declare a function named coordinates that takes a single parameter of type String, with an external name for, a local name of location

You're missing the external name, it should be :

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

func coordinates(for location: String) -> (lat: Double, lon: 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, 151.2141)
default:
    print("Location not found")
    return(0,0)
}

}
