How do i get a return value of Double, Double from a String parameter?

This question is regarding the test in "returning complex value" for functions in Swift.

functions.swift
// Enter your code below
func coordinates(for location: String) -> (Double, Double) {

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



}

Hello Adam,

You almost have it! Instead of using print, use return and your code should pass the challenge. Like so:

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)
  }
}
