No exact matches in call to initializer error when making a structure with a table view

Question

I am new to coding structures and this is for my school project. I am trying to make a structure with a tableview and I keep on getting the error "No exact matches in call to initializer ."

I have added my whole code in order provide a full picture of my project. My aim with this code is to be able to input a structure of my friends. Each line must include their name, age and best friend status. This must be completed with a structure and please bare with me as I am very new to this.

Thank you for your help!

 import UIKit

 class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return friends.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        //ensure the cell identifier has been labelled "cell"
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        cell.textLabel?.text = String(friends[indexPath.row]) **//error occurs here**
        return cell
    }
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        tblFriends.delegate = self
        tblFriends.dataSource = self
    }
    
    
    // Outlets
    @IBOutlet weak var txtName: UITextField!
    @IBOutlet weak var txtAge: UITextField!
    @IBOutlet weak var swiBestFriendsList: UISwitch!
    @IBOutlet weak var tblFriends: UITableView!
    @IBOutlet weak var lblMessage: UILabel!
    
    
    struct Friend{
        let name: String
        let age: Int
        let bestFriend: Bool
    }
    var friends: [Friend] = []
    
    // Actions
    @IBAction func btnAddFriend(_ sender: Any) {
        if Int(txtAge.text!) != nil && txtAge.text != ""{
            if (txtName.text!) != "" {
                let newFriend = Friend(name: txtName.text!, age: Int(txtAge.text!)!, bestFriend: swiBestFriendsList.isOn)
                friends.append(newFriend)
                print(friends)
                txtAge.text = ""
                txtName.text = ""
                if swiBestFriendsList.isOn{
                    lblMessage.text = "Best Friend has been added"
                    tblFriends.reloadData()
                }
            } else {
                lblMessage.text = "No name entered"
            }
        } else {
            lblMessage.text = "No age entered and must be a number"
        }
    }
