Making a Call From UIButton

In my project I am trying to make a phone call when the UI button is topped. Below is the implementation but when I run it from the Simulator or on my iPhone it doesn’t work. How do I fix it?
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ListOfCarsTableViewCell
let carsIndex = carsArray[indexPath.row]
cell.phoneButton.setTitle(carsIndex.dealer.phone.toPhoneNumber(), for: .normal)

        return cell
        
    }
    
    @objc func callTapped(_ sender: UIButton) {
        let buttonPosition = sender.convert(CGPoint.zero, to: self.tableView)
        if let indexPath = tableView.indexPathForRow(at: buttonPosition){
            let phoneNumber = carsArray[indexPath.row].dealer.phone
            callNumber(phoneNumber: phoneNumber)
        }
        
    }
    
        func callNumber(phoneNumber:String) {
            if let phoneCallURL = URL(string: "\(phoneNumber)") {
                let application:UIApplication = UIApplication.shared
                if (application.canOpenURL(phoneCallURL)) {
                    application.open(phoneCallURL, options: [:], completionHandler: nil)
                }
            }
        }

>Solution :

You can try

    cell.phoneButton.tag = indexPath.row
    cell.phoneButton.setTitle(carsIndex.dealer.phone.toPhoneNumber(), for: .normal)
    cell.phoneButton.addTarget(self, action: #selector(callTapped), for: .touchUpInside)

@objc func callTapped(_ sender: UIButton) {
    let phoneNumber = carsArray[sender.tag].dealer.phone
    callNumber(phoneNumber: phoneNumber)
    
}

Also Don’t forget to add tel:// before phone number
