How would one print the coords/result with out the word "Point" to console. Display (1,1)... vs Point(x: 1, y:1)

How can one print the coordinates/result without the word "Point" to the console? Currently prints as follows: [Point(x: 1, y: 1), Point(x: 1, y: 2), Point(x: 1, y: 3), Point(x: 2, y: 1), Point(x: 2, y: 2), Point(x: 2, y: 3), Point(x: 3, y: 1), Point(x: 3, y: 2), Point(x: 3, y: 3)]

What I want to be able to do is just have the coordinates themselves printed as follows: [(1,1), (1,2),(1,3)...etc.]

You'd need to use the description property to do this.

  1. Conform your class/struct/enum to CustomStringConvertible
  2. Add var description as a computed property according to your desired output

For example:

struct Point: CustomStringConvertible {
  var latitude: Double
  var longitude: Double

  var description: String {
    return "(\(latitude),\(longitude))"
 }
}
