iOS Functions in Swift Adding Power to Functions Returning Complex Values

I am declaring a Parameter of type String but it keeps telling me that I am not, somebody please help

As you can see in my code after

func coordinates

my argument is (location: String)

the error that I'm receiving is that my function argument isn't of type String.

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)
    }
}

Hey Shawn,

The error is definitely misleading as you do have a parameter of type String. However, the instruction ask you to

Declare a function named coordinates that takes a single parameter of type String, with an external name for, a local name of location, and returns a tuple containing two Double values

In your function, you are missing the external name "for".

Keep coding! :dizzy:
