Where am i going wrong here?

functions return complex values

functions.swift 
// Enter your code below
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 "Syndey Opera House": return (33.8587,151.2140)
    default: return (0,0)
  }

  return (location)
}

You pretty much have the correct answer except for a couple issues. Primarily, you don't need to return the location. The switch statement is returning the tuple for you. Your function is expecting you to return a tuple of types Double, not the location parameter. Also, make sure you spell Sydney Opera House correctly.

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)
  }
}
