Data not showing up in UITableView - ios

Question

class TableController: UIViewController {
#IBOutlet var ListTable: UITableView!
var list: [Dictionary<String, String>] = []
override func viewDidLoad() {
super.viewDidLoad()
let ListTable = UITableView(frame: view.bounds)
self.ListTable = ListTable
ListTable.dataSource = self
ListTable.delegate = self
initList()
}
func initList() {
// get list from firebase
self.ListTable.reloadData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return list.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let item = self.list[indexPath.row]
let cellIdentifier = "ListCell"
let cell = CustomCell(style: .default, reuseIdentifier: cellIdentifier)
cell.foodLabel?.text = item["Banana"]
return cell
}
}
extension QueueController: UITableViewDataSource, UITableViewDelegate {
}
CustomCell class:
import UIKit
class CustomCell: UITableViewCell
{
#IBOutlet weak var foodLabel: UILabel!
override func awakeFromNib()
{
super.awakeFromNib()
}
}
My data from firebase loads properly. On storyboard I have a normal view controller with a UITableView embedded inside of it. That table view is liked to my IBOutlet for my ListTable. In the table there is a cell with 3 labels. That cell has the identifier ListCell and it's class is CustomCell.
Edit: There is no error but my data isn't showing up.

Answer 1

This is because your Custom Cell does not dequeue properly. Try this one
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellIdentifier = "ListCell"
var cell : ListCell? = tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as! ListCell?
if (cell == nil) {
cell = Bundle.main.loadNibNamed("ListCell", owner: nil, options: nil)?[0] as? ListCell
}
cell?.backgroundColor = UIColor.clear
cell?.contentView.backgroundColor = UIColor.clear
return cell!
}

Answer 2

Perhaps try registering your cell in viewDidLoad
ListTable.register(UINib(nibName: "CustomCell", bundle: Bundle.main), forCellReuseIdentifier: "ListCell") //this is assuming that your nib is named "CustomCell"
Also, for the record, you should follow camel-case conventions and name your UITableView listTable

Answer 3

You did never add the TableView to your view... (or part go the code is missing )
