UITableView Displaying Incorrectly - swift

Question

I am trying to use a UITableView by implementing the code I saw on many tutorials but it doesn't work correctly when I run it. What am I doing wrong? I added a cell to the view and added a corresponding identifier. My storyboard look like that
and code is the following:
import UIKit
import Firebase
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var ref: DatabaseReference?
var data = ["m","2","3"]
#IBOutlet weak var tableV: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableV.delegate = self
tableV.dataSource = self
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return data.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableV.dequeueReusableCell(withIdentifier: "PostCell")
cell?.textLabel?.text = data[indexPath.row]
return cell!
}
}
And
what it looks like.
Please help me to solve this problem.

Answer 1

You should use this way to correct errors.
change this:
let cell = tableV.dequeueReusableCell(withIdentifier: "PostCell")
with:
let cell = tableV.dequeueReusableCell(withIdentifier: "PostCell", for: indexPath)
and you need to check cell identifier.
