Having trouble with the returning complex values code challenge

I'm getting an error saying that I'm not declaring a single parameter of type String. Not sure what I'm doing wrong.

functions.swift
// Enter your code below


func coordinates(location: String) {


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

You are not returning two Double values as asked in the question. Also, you cannot use 'lat' and 'lon' keywords as they are not declared anywhere within the program. Hope this will help you :)

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)

  }
}
