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 (Note: You do not have to name the return values). For example, if I use your function and pass in the string "Eiffel Tower" as an argument, I should get (48.8582, 2.2945) as the value. If a string is passed in that doesnβt match the set above, return (0,0)
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)
}
}

21,844 PointsWow, it took longer than I thought but mine was finally accepted with the above correction from Michael Ayoub.
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)
}
}

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

21,844 PointsOriginally mine would not work because I kept trying "forLocation location." I don't really understand why that didn't work. I thought that was what it meant to name the external name as for.
func coordinates(forLocation location: String) -> (Double, Double) {
