why this code not working

The error says Make sure you accept a single parameter of type String in your function declaration

functions.swift 
// Enter your code below

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)
    }

}

coordinates("job")

you forgot the for in the function parameter, the code challenge was very specific about it.

Declare a function named coordinates that takes a single parameter of type String, with an external name for, a local name of location

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

other than that, your function definition is fine, hope it helps. :)

i should point out that technically this code challenge only asks that you implement the coordinates function, it doesn't ask that you call the function; therefore, it's fine to delete the last line in your code.
