How to print out the status here?

In this example, how would you print out the status (rather than it just saying Enum Value)?

I think I figured it out:

You can just add raw values to the enum and then use:

task.status.rawValue

Am I right?

I don't believe there's a way to do this yet. There's a couple work arounds for this. One of which would be adding a String Description as a raw value to each case. Another way would be to create a func with a switch case I believe which would return a value dependant on self.

You can. Just add rawValues to the enum

enum Status: String {
        case Doing = "Doing", Pending = "Pending", Completing = "Completing"

        init() {
            self.init()
        }
    }

and then:

var task = Task(description: "Learn Swift", status: .Pending)
println("\(task.status.rawValue)")

I actually worked on this when completing the challenge. My solution was to use a method within the struct.

    func printStatus() {
        let status = self.status
        if status == Task.Status.Completed {
            println("This task has been completed")
        } else if status == Task.Status.Doing {
            println("This task is being done")
        } else if status == Task.Status.Pending {
            println("This task is pending")
        } else {
            println("Error! I don't know what the status is.")
        }
    }
