Now that you’ve got a handle on switch statements, there’s one more important thing to cover about enumerations.

``````enum TwoDimensionalPoint {

``````case origin

``````case onXAxis(Double)
case onYAxis(Double)

``````case noZeroCoordinate(x: Double, y: Double)

``````let coordinates = (1.0, 3.0)
let twoDimensionalPoint: TwoDimensionalPoint

``````switch coordinates {

``````case (0, 0):
