Why do I keep getting wrong on this?

I don´t get this.

functions.swift 
// Enter your code below
func Coordinates (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)
    }
}

Two things are incorrect with your code

  1. The function is coordinates with lowercase you have Coordinates
  2. You are missing the external name of "for" in you argument
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)
    }
}
