Can't get the data on class uitableview Swift 3 - ios

Question

I'm having trouble presenting the data. I have copied the code from https://stackoverflow.com/a/39307841/7118403 because i want to test his method on saving the checkmark. But unfortunately I can't present the data on tableView. When i try to print the "myItems" it shows [tableViewCheckmark.Item]. I can't seem to find the solution. PS. I'm a new to programming. Thank you in advance.
class Item {
let name : String
var selected = false
init(name: String) {
self.name = name
}
}
class TableViewController: UITableViewController {
#IBOutlet var uiTableView: UITableView!
var myItems = [Item]()
override func viewDidLoad() {
uiTableView.reloadData()
}
override func viewWillAppear(_ animated: Bool) {
let item = Item(name:"Foo")
myItems.append(item)
print(myItems)
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath)
let item = myItems[indexPath.row]
cell.textLabel!.text = item.name
cell.accessoryType = item.selected ? .checkmark : .none
cell.selectionStyle = .none
cell.tintColor = UIColor.green
return cell
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
saveDefaults()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return myItems.count
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let item = myItems[indexPath.row]
item.selected = true
tableView.reloadRows(at: [indexPath as IndexPath], with: .none)
}
func saveDefaults() {
let selectedCells = myItems.filter { $0.selected }.map { $0.name }
let defaults = UserDefaults.standard
defaults.set(selectedCells, forKey:"selectedCells")
}
func readDefaults()
{
let defaults = UserDefaults.standard
let selectedItems = defaults.stringArray(forKey: "selectedCells")!
for item in myItems {
item.selected = selectedItems.contains(item.name)
}
tableView.reloadData()
}
}

Signature of UITableViewDataSource methods is changed in Swift 3 also you are currently passing array count in numberOfSections(in:) remove it and add below methods.
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return myItems.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath)
let item = myItems[indexPath.row]
cell.textLabel!.text = item.name
cell.accessoryType = item.selected ? .checkmark : .none
cell.selectionStyle = .none
cell.tintColor = UIColor.green
return cell
}
override func tableView(tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let item = myItems[indexPath.row]
item.selected = true
tableView.reloadRows(at: [indexPath], with: .none)
}
