Permanent storage To-Do App Swift - swift3

Question

I've got a simple to do list app, and I would like the items in the list to appear after the app is closed. What I have so far does not do it, not sure if everything is in the right place?
Code in my first ViewController:
var list = [String]()
class FirstViewController: UIViewController,UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var myTableView: UITableView!
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return list.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "cell")
cell.textLabel?.text = list[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
list.remove(at: indexPath.row)
myTableView.reloadData()
}
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(_ animated: Bool) {
myTableView.reloadData()
if let x = UserDefaults.standard.object(forKey: "cell") as? [String]! {
list = x
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
Code in my second ViewController:
class SecondViewController: UIViewController {
#IBOutlet weak var input: UITextField!
#IBAction func addItemButton(_ sender: AnyObject) {
list.append(input.text!)
input.text = ""
UserDefaults.standard.set(input.text, forKey: "cell")
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}

Answer 1

You are reloading the tableview at viewDidAppear before getting the data. Get your data from user defaults first (set list) and then reload the table view.
Hint:-
override func viewDidAppear(_ animated: Bool) {
if let x = UserDefaults.standard.object(forKey: "cell") as? [String]! {
list = x
myTableView.reloadData()
}
}
