iOS Swift 2.0 Functions Function Parameters Returning Complex Values

I am having trouble finding out what this means by returning tuple.

I have made this to where it does return the coordinate values, but I am having trouble as to what it keeps asking for with the tuple value.

functions.swift 
func getTowerCoordinates(location: String) {
    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)
}
return location
}

Tuple is where you return more than variable. Try adding something like this above the switch:

let lat = 0 let long = 0

then adjust your switch to something like:

case "Eiffel Tower": lat = 48.8582, long = 2.2945

then finally a return:

return (lat, long)
