Need help with basic functions challenge

Hi guy, I'm stuck on this challenge at the moment. I'm pretty sure it's a syntax issue but I cant find a workaround in the Swift Documents. If you can see something I can't some help would be really appreciated. Thanks

functions.swift
// Enter your code below
func coordinates (for location: String) -> (Double, Double) { 
     switch location {
     case "Eiffel Tower": (48.8582, 2.2945)
     case "Great Pyramid": (29.9792, 31.1344)
     case "Sydney Opera House": (33.8587, 151.2140)
     default: (0,0)
     }
}

Hey David, it is indeed a simple syntax error. You forgot to return the coordinates in the body of your switch statement. Try this and it should work:

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)
    }
}
