Equatable protocol not called when enum compared in switch case.
Here is my code
`import Foundation
public enum AMSelectionStyle{
case single
case multiple
case any
}
public enum AMCalenderMode{
case date
case time
case dateTime
case any
}
public enum AMNumberType:String{
case natural = "N" //(also called positive integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …}
case whole = "W" //This is the set of natural numbers, plus zero, i.e., {0, 1, 2, 3, 4, 5, …}.
case integer = "Z" // This is the set of all whole numbers plus all the negatives (or opposites) of the natural numbers, i.e., {… , ⁻2, ⁻1, 0, 1, 2, …}
case rational = "Q" //This is all the fractions where the top and bottom numbers are integers; e.g., 1/2, 3/4, 7/2, ⁻4/3, 4/1 [Note: The denominator cannot be 0, but the numerator can be].
case real = "R" //(also called measuring numbers or measurement numbers). This includes all numbers that can be written as a decimal. This includes fractions written in decimal form e.g., 0.5, 0.75 2.35, ⁻0.073, 0.3333, or 2.142857. It also includes all the irrational numbers such as π, √2 etc. Every real number corresponds to a point on the number line.
case all = "" // all of the above
}
