2,278 Pointsswift tuple functions
I would like some help on tuple within a function. I need to have a function with a local of location and return two double. i.e. user needs to input a name, if it matches a case then print out its coordinates.
// Enter your code below
func coordinates(for location: String) -> (lat: Double, long: Double)
{
let value //Possibly need a constnt of Value...
switch location
{
case "Eiffel Tower": print(48.8582, 2.2945)
case "Great Pyramid": print(29.9792, 31.1344)
case "Sydney Opera House": print(33.8587, 151.2140)
default: print(0,0)
}
return () //Need to return Tuple of string to double...
}

23,970 PointsHere is what is wrong with your code :)
- The task states not to name the return Doubles so there is no need for the lat and long
- You don't need the let value
- The task does not ask you to print anything; therefore, you can replace your print with return and you will be returning the tuple the you are looking for
- You can remove the return () you have at the end
Your correct code will look like the 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)
}
}

2,278 PointsThanks Jeff! I spent two day trying to figure it out, but it seems I was overthinking it.
