Could you show me where I’m going wrong?

Can’t seem to figure this one out.

functions.swift 
// Enter your code below

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

 }

Your code is very close to correct. The issue is that you are switching on coordinates (the function) rather than location (the string passed to the function). If you fix that issue like this:

func coordinates(for location: String) -> (Double, Double) {
  switch location { // coordinates changed to 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)
  }
}

Then your code will work perfectly fine.
