@IBAction func imageRoll(_ sender: UIBarButtonItem) {
    _ = imageArray.shuffle()
    tableView.reloadData()
}

@IBAction func addImage(_ sender: UIBarButtonItem) {

extension ViewController: UITableViewDataSource, UITableViewDelegate {

func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return imageArray.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: “ImageCell", for: indexPath) as! ImageTableViewCell
    let images = imageArray[indexPath.row]

    cell.imageCell.image = images

    return cell
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == .delete {
        imageArray.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .automatic)
    }

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 40

Firstly declare tableview cell globally:-

var cell : ImageTableViewCell?

Create image array to save in user default:-

var saverImageArr = [UIImage?]()

Now when button is pressed:-

@IBAction func imageRoll(_ sender: UIBarButtonItem) {
    for image in 0..<imageArray.count {
        if saverImageArr.count > 0
        {
            saverImageArr.removeAll()
        }

        saverImageArr.append(cell.imageCell.image)
    }
    UserDefaults.standard.set(saverImageArr, forKey: "imageArray")
    UserDefaults.standard.synchronize()
    tableView.reloadData()
}

Now to get that array from user default:-

if let imageArrfromUserdefault = UserDefaults.standard.array(forKey: "imageArray")
   {
        print(imageArrfromUserdefault)
   }
   else
   {
        print("empty array")
   }

Thank you.
