Here is the question: 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 doesnβt match the set above, return (0,0)
func coordinates()

23,970 PointsHi Joshua - You want to first declare a function named coordinates (which I see that you have). The function takes a single parameter of type string with external name for and local name of location. You place the for before location because it is the external name. You then need to create a switch statement that will switch output depending on the case selected. Finally you need to create a default case at the end of the switch statement
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)
}
}
