Answer 1

If you want array to mutable declare it as var instead of let. and Create 1 var numberOfRecordtoShow
var animalNames = ["lion","monky","tiger"]
var animalImages = [UIImage(named: "lion"), UIImage(named: "monky"), UIImage(named: "tiger")]
var numberOfRecordtoShow = 1
Increate numberOfRecordtoShow by 1 till array count.
#IBAction func addingImages(_ sender: UIButton) {
if numberOfRecordtoShow > animalNames.count{
return
}
numberOfRecordtoShow = numberOfRecordtoShow + 1
//reload table now
tableView.reloadData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return numberOfRecordtoShow
}
