  ` A textual representation of this instance, suitable for debugging.

  Calling this property directly is discouraged. Instead, convert an
  instance of any type to a string by using the `String(reflecting:)`
  initializer. This initializer works with any type, and uses the custom
  `debugDescription` property for types that conform to
  `CustomDebugStringConvertible`:

      struct Point: CustomDebugStringConvertible {
          let x: Int, y: Int

          var debugDescription: String {
              return "(\(x), \(y))"
          }
      }

      let p = Point(x: 21, y: 30)
      let s = String(reflecting: p)
      print(s)
      // Prints "(21, 30)"

  The conversion of `p` to a string in the assignment to `s` uses the
  `Point` type's `debugDescription` property.

  #### Declaration

  Swift

      var debugDescription: String { get }
