How to do it?


A: you need to maintain a quantityArray to store current quantity of every index
var quantityArray:[Int] = [] //initialize quantity array

then add initial quantity values to quantityArray
For example : If your list array count 10 and initial quantity of all item will be one means
add initial values to the array
for i in 0 ..< 10 {
   quantityArray.append(1)
}

then in your tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)
assign quantity value from quantityArray
cell.qtyLbl.text = "\(quantityArray[indexPath.row])"
cell.incrementBtn.tag = indexPath.row
cell.incrementBtn.addTarget(self, action: #selector(self.incrementBtnClicked(_:)), for: .touchUpInside)
cell.decrementBtn.tag = indexPath.row
cell.decrementBtn.addTarget(self, action: #selector(self.decrementBtnClicked(_:)), for: .touchUpInside)

add below functions into your viewcontroller
func incrementBtnClicked(_ sender:UIButton){
    let increasedQty = quantityArray[sender.tag]+1
    self.quantityArray.replaceSubrange(sender.tag, with: increasedQty)
    self.tableView.reloadData
}

func decrementBtnClicked(_ sender:UIButton){
    let decreasedQty = quantityArray[sender.tag]-1
    self.quantityArray.replaceSubrange(sender.tag, with: decreasedQty)
    self.tableView.reloadData
}

If you use like this even after scroll tableview also quantity in the cell will be populated from quantity array
Hope this will help you

A: All you have to do is to add an action to your button and do your job.
@IBAction func increase() {
    quantityLabel.text = "\(quantity)" // increase the quantity number and set it
}

btw. before getting any help you should consider posting your code.
