How to see a value of Enum

I managed to write my own code but I have a question regarding an Xcode. On the right panel there is a Enum value but how can see what that value is. For example: I have a new instance and I want to see a status, how can I see it (lets pretend I didn't write that code and I don't know what statuses are available)

you can use the rawValue attribute.

You can also create a function which displays a String value for the enum you created

 enum Status{
    case Pending
    case Doing
    case Completed

    init(){
        self = .Pending
    }

    func toString() -> String{
        switch self{
        case .Pending:
            return "Pending"
        case .Doing:
            return "Doing"
        case .Completed:
            return "Completed"
        default :
            return "Not a valid status"
        }
    }
}
struct Task {
    var description : String
    var status = Status()

    init(description : String){
        self.description = description
    }
}
var taskOne = Task(description: "Shower")
taskOne.status.toString()
taskOne.status = Status.Completed
taskOne.status.toString()
