I do not understand the problem with the code

What does the error want me to change?

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 "Sydney Opera House" : return (33.8587,151.214)
    default : return (0,0)
  }
}

Hi Hosni,

You've pretty much got it, except for two small typing errors in the function declaration.

  1. The external variable name should be for with a lower-case "f" ... you have an upper-case "F"
  2. To signify the return is the symbol -> (one hyphen and the greater than symbol) ... you have 2 hyphens
func coordinates(for location : String) -> (Double, Double)

Good Job & Keep Coding! :) :dizzy:
