If we were going to model the different testing requirements in an object-oriented way, we would start off by creating a super class that contained all of the testing areas even though not all subclasses will need all of the testing areas. We would then create sub-classes of this super-class that would contain the individual requirements for each of the tests. Before we see how we would do this in an object-oriented way, let's create two enumerations that will define the different belt colors and ranks. We will also create a type alias that will define the board break requirements. The following code shows how we would define these:

enum TKDBeltColors: Int { case White, Yellow, Orage, Green, Blue, Purple, Red, FirstDegreeBlack, SecondDegreeBlack, ThirdDegreeBlack, ForthDegreeBlack } enum TKDColorRank: Int { case NoRank, Probationary, Decided, Intermediate, Senior } typealias BoardBreak = (name: String, required: Bool)
