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
}
public enum AMInputType:Equatable {
case list(AMSelectionStyle)
case number(AMNumberType)
case calender(AMCalenderMode)
case freeText
case boolian

public static func ==(lhs: AMInputType, rhs: AMInputType) -> Bool {

Hello Team,
We are Testing Health Records feature into our Patient Application. We have imported sample data available in Simulator and modelling it using FHIR Model. We are trying to group test results based on Origin(Lab Name and Result Date) of Lab Reports. But we are not able to retrieve Lab Name and Lab Test Panel Mapping information.
