Table View Cell by Cell out of an array - ios

Question

I am new to Swift and as a little Project I would like to create something like a "Choose your own Adventure Game".
I try to achieve this through a TableView in which every Cell contains a Line of the Story out of an Array.
With my current Code on App Start every Cell is generated Instant and is displaying the Strings of the Array - which is correct but I would like to generate every Cell over Time.
Optional: If possible it would be great to show the String in each Cell Char by Char with a delay so the Characters show up one by one with 0.5 Seconds delay - after First String/Cell is completed this way it should generate the second Cell and write out the second String.
Do you have any suggestions how I can achieve this?
Thanks!
Here is my current Code which is not including any functionality for the Delay since I don't know how to manage this :)
import UIKit
class ViewController: UIViewController {
var storyLines = ["Test Cell 1 and so on first cell of many","second cell bla","aaaand third cell sup"]
var actualTables = 1
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
tableView.dataSource = self
}
#IBOutlet weak var tableView: UITableView!
}
extension ViewController : UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return storyLines.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TxtLine", for: indexPath)
cell.textLabel?.text = storyLines[indexPath.row]
cell.textLabel?.numberOfLines = 0;
cell.textLabel?.lineBreakMode = .byWordWrapping
return cell
}
}

There is an instance method named tableView(_:willDisplay:forRowAt:) in uitableviewdelegate. You can override that method and have your table view cell animated. You can refer the code below as an example.
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
cell.transform = CGAffineTransform(translationX: tableView.bounds.width, y: 0)
UIView.animate(
withDuration: 0.5,
delay: 0.05 * Double(indexPath.row),
options: [.curveEaseInOut],
animations: {
cell.transform = CGAffineTransform(translationX: 0, y: 0)
})
}
}
And don't forget to set your viewcontroller as delegate to your tableview.
tableview.delegate = self
