4,074 PointsThe challenge will not let me see anything in the Preview window. It says that my code will not compile.
So can you fix this so that I can 'see' the errors being returned? It works in xCode.
// code challenge ------------------------------------------------------------- class Point99 { var x: Int var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
class Machine { var location: Point99
init() {
self.location = Point99(x: 0, y: 0)
}
func move(direction: String) {
print("Do nothing! Im a machine!")
}
}
// Enter your code below
class Robot: Machine {
override init() {
super.init()
}
override func move(direction: String){ switch direction { case "Up": self.location.y + 1 case "Down": self.location.y - 1 case "Left": self.location.x - 1 case "Right": self.location.x + 1 default: break } }
}//end of subclass Robot
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! I'm a machine!")
}
}
class Robot: Machine {
override func move(direction: String) {
switch direction {
case "Up": location.y += 1
case "Down": location.y -= 1
case "Left": location.x -= 1
case "Right": location.x += 1
default: break
}
}
}

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! I'm a machine!")
}
}
class Robot: Machine {
override func move(_ direction: String) {
switch direction {
case "Up":
location.y += 1
case "Down":
location.y -= 1
case "Left":
location.x -= 1
case "Right":
location.x += 1
default:
break
}
}
}
