Last Challenge in swift 3 functions

Eiffel Tower - lat: 48.8582, lon: 2.2945 Great Pyramid - lat: 29.9792, lon: 31.1344 Sydney Opera House - lat: 33.8587, lon: 151.2140

Declare a function named coordinates that takes a single parameter of type String, with an external name for, a local name of location, and returns a tuple containing two Double values (Note: You do not have to name the return values). For example, if I use your function and pass in the string "Eiffel Tower" as an argument, I should get (48.8582, 2.2945) as the value. If a string is passed in that doesn’t match the set above, return (0,0)

beats me...any help out there?????????

Hey Rich,

You need to use a switch inside the function and return a tuple for the coordinates to each location.

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)

coordinates(for: "Eiffel Tower")
