functions.swift 
// Enter your code below
func getTowerCoordinates(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)

Hi. There're quite a few issues with the code.

  • "EIffel Tower" is a misspelled, only the first letter of Eiffel needs to be capitalized.
  • The use of print() statements are incorrect here.
  • Right before the switch statement, you need to declare a variable, type (Double, Double), and assign value to the variable at each case in the switch statement, on top of that, this variable also serves as the return value of the function.
  • last but not least, it's essential to properly indent your code block for better readability. Clean code matters.
// Enter your code below
func getTowerCoordinates(location: String) -> (Double, Double) {
  var coordinate: (Double, Double)
  switch location {
    case "Eiffel Tower": coordinate = (48.8582 , 2.2945)
    case "Great Pyramid": coordinate = (29.9792 , 31.1344)
    case "Sydney Opera House": coordinate = (33.8587 , 151.2140)
    default: coordinate = (0,0)
  }
  return coordinate
}

Hope it helps. Please refer to this lecture for refreshing on the materials
