Return a Tuple containing two Double values

Hello, everyone!

Below are my codes. But i got an error saying "Your function needs to return a Tuple containing two Double values."

I cannot find what I did wrong. Can anybody please help?

Many thanks!!

functions.swift 
// Enter your code below
func coordinates(for location: String) -> (lat: Double, lon: 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)

}

}

Hi Kuladej,

Your code is absolutely fine. There is a small note given in the challenge-

(Note: You do not have to name the return values)

Treehouse challenges need to be solved by following every small instruction given in the question. So just remove the names from your function's return values. Hope this helps :)

func coordinates(for location: String) -> (Double, Double)
