Swift - Delegate function not returning value

VC-A is embedded in a nav controller and has a button going to VC-B via a popover segue. VC-B has a table view with a few font names. When I select a font name, VC-B closes and, using delegate/protocol, VC-A should get the selected name. It does not. I found that if I set a breakpoint at the end of didSelectRowAt, delegate is nil for some reason.

VC-A

class ViewController: UIViewController, FontDelegate {
    @IBOutlet weak var infoLabel: UILabel!
    let fontTable = FontTableTableViewController()

    override func viewDidLoad() {
        super.viewDidLoad()
        fontTable.delegate = self
    }
    
    func getFontName(data: String) {
        infoLabel.text = data
    }
}

VC-B

protocol FontDelegate {
    func getFontName(data: String)
}
    
class FontTableTableViewController: UITableViewController {

   let fontArray = ["Helvetica", "Arial", "Monaco"]
   var delegate: FontDelegate?

   // MARK: - Table view functions go here...

   override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
      let font = fontArray[indexPath.row]
      self.delegate?.getFontName(data: font)
      self.dismiss(animated: true, completion: nil)
   }
}

This shows the storyboard connection from the button in VC-A to VC-B.
