What's wrong with my code, I don't understand

Hi so my code is not working and I want to implement a few new things in to the code these things are to be placed in the order they are displayed in this post although I´m posting them as ´´//`´in the post. What im trying to to is an automatic UIView which is also able to respond to interactions such as a drag. Hopefully the code will explain easier what im trying to achieve here.

import UIKit

class ViewController: UIViewController {
    
    
    @IBOutlet var collectioView: UICollectionView!
    @IBOutlet var myPage: UIPageControl!
    
    var SliderImages:[String]=["3","",""]
     // var SliderImages = [UIImage(named: "2")!, UIImage(named: "2")!, UIImage(named: "2")!]
     // var timer : Timer?
     // var currentCellIndex = 0
    
    // var currentPage:Int=0

    override func viewDidLoad() {
        super.viewDidLoad()
        collectioView.delegate = self
        collectioView.dataSource = self
        // pageControl.numberOfPages = SliderImages.count
        myPage.currentPage=0
        myPage.numberOfPages=SliderImages.count
        
        // startTimer()
    }
    
    // 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

extension ViewController : UICollectionViewDataSource , UICollectionViewDelegate {
    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
    }
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int{
        return SliderImages.count
    }
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! MyCollectionCell
        cell.myWebImage.image=UIImage(named: SliderImages[indexPath.row])
        return cell
    }
    
    func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
        myPage.currentPage=indexPath.row
        
         // func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSIZE { return CGSize(width: collectionView.frame.width, height: collectionView.frame.height.
      }
    
     // func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat { return 0
}

So I’ve run this code and it’s obviously wrong and of course while it says what’´s wrong I don’t really know how to fix this. Thanks for any kind of response!
