with an external name "for" -- this is a key word of "for" loop

strange challenge task

functions.swift 
// Enter your code below
func coordinates(forLocation location: String = "") -> (Double, Double) {
  switch location {
    case "Eiffel Tower": return (48.8582, 2.2945)
    default: (0.0, 0.0)
  }
}

I am not sure if you are asking a question her, but there is no for loop?

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)
    }
}

coordinates(for: "Eiffel Tower")
