Challenge Task 1 of 1
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)
// Enter your code below
func coordinates (for location : String) -> (Double, Double){
eiffelTower - lat = 48.8582, lon = 2.2945;
greatPyramid - lat = 29.9792, lon = 31.1344;
sydneyOpera House - lat = 33.8587, lon = 151.2140;
}
var loc = coordinates (for : "eiffelTower")

17,748 PointsYou can use a switch statement on the location parameter which returns a tuple of doubles
// Enter your code 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)
}
}
