In this challenge, we have the following geographical coordinates
Eiffel Tower - lat: 48.8582, lon: 2.2945 Great Pyramid - lat: 29.9792, lon: 31.1344 Sydney Opera House - lat: 33.8587, lon: 151.2140
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 doesn’t match the set above, return (0,0)
// Enter your code below
func coordinates (for location : String) -> (lat : Double, lon : Double){
var lat = 0.0
var lon = 0.0
switch location{
case "Eiffel Tower" :
lat = 48.8582
lon = 2.2945
case "Great Pyramid" :
lat = 29.9792
lon = 31.1344
case "Sydney Opera House" :
lat = 33.8587
lon = 151.2140
default :
lat = 0.0
lon = 0.0
}
return (lat , lon)
}
var loc = coordinates (for : "Eiffel Tower")
loc.lat
loc.lon

13,117 PointsIn the challenge it is mention that -> (Note: You do not have to name the return values) just remove the names of the return values.
// Enter your code below func coordinates (for location : String) -> (Double, Double){ var lat = 0.0 var lon = 0.0 switch location{ case "Eiffel Tower" : lat = 48.8582 lon = 2.2945 case "Great Pyramid" : lat = 29.9792 lon = 31.1344 case "Sydney Opera House" : lat = 33.8587 lon = 151.2140 default : lat = 0.0 lon = 0.0 } return (lat , lon) }
var loc = coordinates (for : "Eiffel Tower")

14,084 PointsThis is just passed for me:
// Enter your code below
func coordinates (for location : String) -> (Double, Double) {
var lat = 0.0
var lon = 0.0
switch location{
case "Eiffel Tower" :
lat = 48.8582
lon = 2.2945
case "Great Pyramid" :
lat = 29.9792
lon = 31.1344
case "Sydney Opera House" :
lat = 33.8587
lon = 151.2140
default :
lat = 0.0
lon = 0.0 }
return (lat , lon) }
var loc = coordinates (for : "Eiffel Tower")

4,704 PointsThis seems cleaner (and just passed for me):
func coordinates(for location: String) -> (Double, Double) {
var lat = 0.0
var lon = 0.0
switch location {
case "Eiffel Tower": lat = 48.8582; lon = 2.2945
case "Great Pyramid": lat = 29.9792; lon = 31.1344
case "Sydney Opera House": lat = 33.8587; lon = 151.2140
default: lat = 0.0; lon = 0.0
}
return (lat, lon)
}
