Stepper on tableview cell (swift)

I put stepper both outlets and action into tableview cell and using protocol delegate to connect it to tableview. When i tapped stepper in first row, stepper value appear normaly in first row but its also appear in some random row. how to fix this?

TableViewCell

protocol ReviewCellDelegate{
    func stepperButton(sender: ReviewTableViewCell)
}

class ReviewTableViewCell: UITableViewCell {
   @IBOutlet weak var countStepper: UIStepper!
   @IBOutlet weak var stepperLabel: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

@IBAction func stepperButtonTapped(sender: UIStepper) {
    if delegate != nil {
        delegate?.stepperButton(self)
        stepperLabel.text = "x \(Int(countStepper.value))"

    }
}

ViewController

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellIdentifier = "reviewCell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! ReviewTableViewCell


    var imageView: UIImageView?
    let photoG = self.photos[indexPath.row]
    imageView = cell.contentView.viewWithTag(1) as? UIImageView
    //let layout = cell.goodiesImage
    let tag = indexPath.row // +1
    cell.tag = tag
    photoG.fetchImageWithSize(CGSize(width: 1000, height: 1000), completeBlock: { image, info in
        if cell.tag == tag {
            imageView?.image = image
            cell.goodiesImage.image = image
        }
    })

func stepperButton(sender: ReviewTableViewCell) {
    if let indexPath = tableView.indexPathForCell(sender){
        print(indexPath)
    }
}

As mentioned by @A-Live, your component is being reused and so need to be updated.

So in your view controller:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellIdentifier = "reviewCell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! ReviewTableViewCell


    var imageView: UIImageView?
    let photoG = self.photos[indexPath.row]
    imageView = cell.contentView.viewWithTag(1) as? UIImageView
    //let layout = cell.goodiesImage
    let tag = indexPath.row // +1
    cell.tag = tag
    photoG.fetchImageWithSize(CGSize(width: 1000, height: 1000), completeBlock: { image, info in
    if cell.tag == tag {
        imageView?.image = image
        cell.goodiesImage.image = image
    }
})
    cell.countStepper.value = XXX[indexPath.row].value; //Here you update your view
    cell.stepperLabel.text = "x \(Int(cell.countStepper.value))" //And here

And

func stepperButton(sender: ReviewTableViewCell) {
    if let indexPath = tableView.indexPathForCell(sender){
        print(indexPath)
        XXX[sender.tag].value = sender.counterStepper.value //Here you save your updated value
}
