Challenge Task 1 of 1

For this challenge, let's say we're building a component of an app that allows a user to type in a location of a famous landmark and get back the geographical coordinates.

To keep the scope limited, let's say we're only working with the following values.

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 getTowerCoordinates that takes a single parameter of type String, named location, and returns a tuple containing two Double values (Note: You do not have to name the return values)

Use a switch statement to switch on the string passed in to return the right set of coordinate values for the location.

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.

For the default case in the switch statement, return (0,0).

Here you go:

func getTowerCoordinates(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)
    }
}

let test = getTowerCoordinates("Eiffel Tower")

The function takes a String and returns a tuple made up of the lat and long values.
