Swift iOS - UITableView Custom Cell not appearing?-CodePudding

I'm trying to populate my tableView with a custom cell - seems pretty straight forward, but for some reason when I run the following code, the custom cell doesn't appear? I feel like I'm missing something super obvious.

Custom cell name is: OffersTableViewCell

DashboardViewController

class DashboardViewController: UIViewController, UITableViewDelegate, UITableViewDataSource  {

    
 @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.tableView.dataSource = self
        self.tableView.delegate = self
        
        self.registerTableViewCells()
    }

    func tableView(_ tableView: UITableView,
                   numberOfRowsInSection section: Int) -> Int {
        return 10
    }
    
    func tableView(_ tableView: UITableView,
                   cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if let cell = tableView.dequeueReusableCell(withIdentifier: "OffersTableViewCell") as? OffersTableViewCell {
            return cell
        }
        
        return UITableViewCell()
    }
    
    private func registerTableViewCells() {
        let textFieldCell = UINib(nibName: "OffersTableViewCell",
                                  bundle: nil)
        self.tableView.register(textFieldCell,
                                forCellReuseIdentifier: "OffersTableViewCell")
    }
    
 

}

OffersTableViewCell

import UIKit

class OffersTableViewCell: UITableViewCell {

    @IBOutlet weak var offerTitle: UILabel!
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
    
}

I think you should be able to resolve the issue by using the code below. I would suggest we remove UITableViewCell().


    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.tableView.dataSource = self
        self.tableView.delegate = self
        
        self.registerTableViewCells()
        self.tableView.reloadData()
    }

    func tableView(_ tableView: UITableView,
                   cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "OffersTableViewCell", for: indexPath) as! OffersTableViewCell 
        return cell
        //put any other exception conditions to display UITableViewCell() if necessary
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

Make sure you have the Cell named - OffersTableViewCell.swift class, and OffersTableViewCell.xib that is having UI for that cell.

override func viewDidLoad() {
    super.viewDidLoad()
    
    self.registerTableViewCells()

    self.tableView.dataSource = self
    self.tableView.delegate = self
}

func tableView(_ tableView: UITableView,
               cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = tableView.dequeueReusableCell(withIdentifier: "OffersTableViewCell", for: indexPath) as? OffersTableViewCell else { return UITableViewCell() }
     
    cell.offerTitle.text = "blabla.."

    return cell
}

Please register cell before you assign the tableView delegate & datasource. Or just call reloadData after you register cell Nibs.

Also, make sure you are loading safe data otherwise return default TableViewCell please.
