How to make a enum conform to a protocol in Swift.

SimpleEnum

enum SimpleEnum : ExampleProtocol {
    case Base, Adjusted
    
    var simpleDescription: String {
        get {
            return self.getDescription()
        }
    }
    
    func getDescription() -> String {
        switch self {
        case .Base:
            return "A simple description of enum"
        case .Adjusted:
            return "Adjusted description of enum"
        default:
            return "default description"
        }
    }
    
    mutating func adjust() -> Void{
        self = SimpleEnum.Adjusted
    }
}

var c = SimpleEnum.Base
c.simpleDescription
c.adjust()
c.simpleDescription
