Cant figure out why its giving the error?

I believe am returning the tuples, but what am i missing?

functions.swift 
// Enter your code below
func getTowerCoordinates(a: String )-> (lat: Double, lon: Double){
var lat: Double
var lon: Double
switch a{
  case "Eiffel tower": (lat = 48.8582, lon = 2.2945 )
  case "Great Pyramid": (lat = 29.9792, lon = 31.1344 )
  case "Sydney Opera House": (lat = 33.8587, lon = 151.2140)
  default: return(0,0)
}
return (lat, lon)
}

let towerCoordinates = getTowerCoordinates(a:"Great Pyramid")

// Enter your code below

// func getTowerCoordinates(a: String )-> (lat: Double, lon: Double){
// "Note: You do not have to name the return values" –> pretty much means don't do it in this case
func getTowerCoordinates(a: String )-> (Double, Double){
var lat: Double
var lon: Double
switch a{
  // case "Eiffel tower": (lat = 48.8582, lon = 2.2945 )
  // tiny typo with "tower" instead of "Tower"
  case "Eiffel Tower": (lat = 48.8582, lon = 2.2945 )
  case "Great Pyramid": (lat = 29.9792, lon = 31.1344 )
  case "Sydney Opera House": (lat = 33.8587, lon = 151.2140)
  default: return(0,0)
}
return (lat, lon)
}

// if I understand this correctly - swift 2 does not use the name of your variable –  (a: "Great Pyramid")
// it is however required now in swift 3
let towerCoordinates = getTowerCoordinates("Great Pyramid")
