Hey guys,
I found it difficult to know the right syntax (tried various combinations) but I can't seem to remember how to assign which property or class (Point or location) as the way to be able to later return a value after the x or y variable had been changed in each case. Is there a solution that somebody can provide and walk me through in? It feels I can't solve it without some clear cut solution ...
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!")
}
}
// Enter your code below
class Robot: Machine {
override func move(direction: String) {
switch move(direction: String) {
case move(direction: "Up"): location: Point(x: x, y: y + 1)
case move(direction: "Down"): Point(x: x, y: y - 1)
case move(direction: "Left"): Point(x: x - 1, y: y)
case move(direction: "Right"): Point(x: x + 1, y: y)
default: break
}
override init
return location: Point
}
}

Treehouse TeacherOk, I know some about Swift... but not enough to really help you. However, I found this post by Steven Deutsch from about a month ago that's really sort of brilliant at explaining it. To the point where even I get it. Take a peek!

4,435 PointsThanks Steven for your short blurb about the future of Swift and it's potential to stay or grow as a prominent part of computing; I was going to ask this question on Treehouse a few days ago and now I don't have to since it's answered haha

Treehouse TeacherSteven Deutsch You're welcome! If I could give you the best answer, I would. But you'll be helping me soon enough. I was working on the Swift 2.0 track when my Mac Mini died a horrible, horrible death. When I get it replaced I'm sure I'll have plenty of questions :)

21,046 PointsSorry to hear about the Mac :( Sounds good, I love helping people learn about Swift. It's such a beautiful, elegant, and modern language. Google is even considering make it a first class language for Android development. I believe Swift is the future of mobile development
