Functions in Swift

This Code Challenge is asking us to create a function that will return two(2) Doubles (the lat and lon).

To create the function we use the func keyword followed by the name of the function, coordinates. The single parameter is of type String with the external name for and local name location. This is how to correctly write this: (for location: String). To return two(2) Doubles, we must use -> followed by what type we are returning. In this case (Double, Double), two(2) Doubles.

Here is what we have so far.

func coordinates(for location: String) -> (Double, Double) {

}

We can use a switch to assign the names of the locations to their own case and return the lat and lon values. The return should look the same as (Double, Double) but with actual double numbers.

Here's what the switch looks like.

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, 0.0)
  }

Finally, added together!

// 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, 0.0)
  }
}
