Whats wrong with my code? It works in swift but not here in treehouse
// Enter your code below
func coordinates (for location: String) -> (a: Double, b: Double){
var a = 0.0
var b = 0.0
switch location{
case "Eiffel Tower": a = 48.8582; b = 2.2945
case "Great Pyramid": a = 29.9792; b = 31.1344
case "Sydney Opera House": a = 33.8587; b = 151.2140
default: a = 0; b = 0
}
return (a, b)
}

The code compiles because it is valid Swift code. You just didn't solve the question the way Treehouse wanted you to. Instead of assigning the lon/lat values to variables a and b, just return the values directly.
// 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, 151.2140)
default:
return (0, 0)
}
}
You don't have to name the return values inside of the tuple, as stated in the challenge.
Good Luck
Fredrik Carlsson
