Add TableView into .xib View in swift

Question

On clicking button I have a .xib view in which I define a tableView.Here for cell I create another .xib file because there is only option . no default cell is there I think.. so How can I display the items in tableview cell. I have registered the .Xib like this and tried but surprising view I got.

class CustomAddOnVC: UIViewController,UITableViewDataSource,UITableViewDelegate {

let items = ["pk","ak","sk"]

override func viewDidLoad() {
    super.viewDidLoad()
}
 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return items.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    
    let identifier = "Cell"
    var cell: CustomOneCell! = tableView.dequeueReusableCellWithIdentifier(identifier,forIndexPath: indexPath) as? CustomOneCell
    if cell == nil {
        tableView.registerNib(UINib(nibName: "CustomOneCell", bundle: nil), forCellReuseIdentifier: identifier)
        cell = tableView.dequeueReusableCellWithIdentifier(identifier,forIndexPath:indexPath ) as? CustomOneCell
        cell.addOnName.text = items[indexPath.row]
        cell.addOnPrice.text = "£0.0"
    }
    
    return cell
}

Here the items counting came as 3 but the data is populating in the first one only.

And one more thing How can I set the the height of view till the end of all items?? As you can see extra space after the items. If i decrease the size and more items came then again same problem.I want to set the height dynamically according to the items data

I think it is because it does not enter your cell == nil anymore as you register for the first time. Therefore, my suggestion is to move your updating text outside the if statement. Like this:

if cell == nil {
    tableView.registerNib(UINib(nibName: "CustomOneCell", bundle: nil), forCellReuseIdentifier: identifier)
    cell = tableView.dequeueReusableCellWithIdentifier(identifier,forIndexPath:indexPath ) as? CustomOneCell
}
cell.addOnName.text = items[indexPath.row]
cell.addOnPrice.text = "£0.0"`
