switch statements

can someone give me a pointer with this one. Below is a link to the code challenge:

https://teamtreehouse.com/library/build-a-simple-iphone-app-with-swift-20/getting-started-with-ios-development/swift-recap-part-2

class Point { var x: Int var y: Int

init(x: Int, y: Int){
    self.x = x
    self.y = y
}

}

class Machine { var location: Point

init() {
    self.location = Point(x: 0, y: 0)
}

func move(direction: String) {
    print("Do nothing! Im a machine!")
}

}

class Robot: Machine {

override init(){
    super.init()
}


override func move(direction: String){
    switch Point(x: 0, y: 0) {
    case func move(direction: "Up"):
    Point(x: 0, y: y += 1)
   default:
        break

}

}

Here is the correct code, I think you should review the video on switch statement again as your code has multiple syntax errors. good luck :)

class Robot: Machine {

override func move(direction: String){
    switch direction {
    case  "Up": location.y += 1
    case  "Down" : location.y -= 1
    case  "Right": location.x += 1
    case  "Left" : location.x -= 1

    default:
        break
    }
}

}
