Hi im creating an automatic UIIMAGEVIEW in SwiftUI but I can't seem to find the issue, anyone who has any idea?

import UIKit
class ViewController: UIViewController {
@IBOutlet var collectioView: UICollectionView!
@IBOutlet var myPage: UIPageControl!
var SliderImages = [UIImage(named: "3"),UIImage(named: "4"),UIImage(named: "5"),UIImage(named: "2")]
// var SliderImages = [ "3", "4", "5"]
// var SliderImages = [UIImage(named: "2")!, UIImage(named: "2")!, UIImage(named: "2")!]
var timer = Timer()
var counter = 0
override func viewDidLoad() {
super.viewDidLoad()
collectioView.delegate = self
collectioView.dataSource = self
myPage.numberOfPages=SliderImages.count
myPage.currentPage=0
DispatchQueue.main.async {
self.timer = Timer.scheduledTimer(timeInterval: 2.0, target: self, selector: #selector(self.changeImage), userInfo: nil, repeats: true)
}
}
@objc func changeImage(){
if counter < SliderImages.count {
let index = IndexPath.init(item: counter, section: 0)
self.collectioView.scrollToItem(at: index, at: .centeredHorizontally, animated: true)
myPage.currentPage = counter
counter += 1
}else {
counter = 0
let index = IndexPath.init(item: counter, section: 0)
self.collectioView.scrollToItem(at: index, at: .centeredHorizontally, animated: true)
myPage.currentPage = counter
counter = 1
}
}
// func startTimer(){ timer = Timer.scheduledTimer(timeInterval: 2.5, target: self, selector: #selector(moveToNextIndex), userinfo: nil, repeats: true)
}
// @objc func moveToNextIndex(){ if currentCellIndex < SliderImages.count -1{ currentCellIndex += 1
// } else { currentCellIndex = 0
// } currentCellIndex += 1 collectionView.scrollToItem(at: IndexPath(item: curentCellIndex, section: 0), at: .centeredHorizontally, animated: true)
// pageControl.currentPage = currentCellIndex
