Help with unresolved identifier issue in struct method.

Can anyone help me with this code? Or maybe a better suggestion to accomplish this task? It's saying use of unresolved identifier but I thought North was declared in my constant? I'm trying to get it to print out what state you're heading towards depending on your direction. (North = New York, East = Carolinas, South = Florida, West = California) import Foundation

struct CompassPoints {

   let compassDirections = ["North", "East", "South", "West"]

    func stateBound() -> String? {
        for direction in compassDirections {
            switch direction {
            case North:
                return "You're heading towards New York"
            }
        }
    }

}

Try this:

enum CompassPoints {
    case North, East, South, West

    func stateBound() -> String {
        switch self {
        case .North:    return "New York"
        case .East:     return "Carolinas"
        case .South:    return "Florida"
        case .West:     return "California"

        }
    }
}

let North = CompassPoints.North
let Northdir = North.stateBound()
println("You're heading towards  \(Northdir).")
