Get Sprite's position in another class - ios

Question

This is probably a dumb question ,but here is my situation.
I have an SKShapeNode rect that goes from left to right on the screen as follows :
// GameScene.swift
var rect = SKShapeNode()
var counter = 0{
didSet{
rect.position = CGPoint(x: CGFloat(counter) , y: frame.midY)
if CGFloat(counter) > frame.width{
counter = 0
}}}
override func update(_ currentTime: TimeInterval) {
counter = counter + 4
}
In the ViewController.swift I try to get the rect.position like this , which I know is wrong because it creates a new Instance.
//ViewController.swift
let gameScene = GameScene()
#IBAction func button(_ sender: Any) {
// gameScene.rect.position = games.frame.CGPoint(x: 200, y: 400)
print(gameScene.rect.position) // Always returns (0,0)
}
Question: How can I get rect.position in real time from the other class. So that whenever I press the button , I get the actual position of the rect?
UPDATE
On Ron's suggestion I updated the viewDidLoad method in my ViewController.swift from this :
let gameScene = GameScene()
override func viewDidLoad() {
super.viewDidLoad()
if let view = self.spriteView {
// Load the SKScene from 'GameScene.sks'
if let scene = SKScene(fileNamed: "GameScene") {
// Set the scale mode to scale to fit the window
scene.scaleMode = .aspectFill
// Present the scene
view.presentScene(scene)
}}
to this :
var gameScene : GameScene!
override func viewDidLoad() {
super.viewDidLoad()
if let view = self.spriteView {
// Load the SKScene from 'GameScene.sks'
if let scene = GameScene(fileNamed: "GameScene") { // SKScene changed to GameScene
self.gameScene = scene // scene assigned to gameScene variable
// Set the scale mode to scale to fit the window
scene.scaleMode = .aspectFill
// Present the scene
view.presentScene(scene)
}
}
INTENTION
I wanted to get the position of the moving bar when the play button was clicked.
Note that the GameScene only represents a part of the actual screen

Answer 1

When you first transition to your GameScene (Assuming that you are going directly from your GameViewController to your GameScene) create a class level variable for gameScene. Then when you need the information from GameScene use that same variable vs. creating a new GameScene variable
var gameScene: GameScene!
override func viewDidLoad() {
super.viewDidLoad()
if let view = self.view as! SKView? {
// Load the SKScene from 'GameScene.sks'
if let gameScene = GameScene(fileNamed: "GameScene") {
self.gameScene = gameScene
gameScene = .aspectFill
// Present the scene
view.presentScene(gameScene)
}
}
}
func getCoords() {
print("gameScene.rect.position \(gameScene.rect.position)")
}
