Answer 1

Create protocol

 protocol HomeTableViewCellDelegate {
    func bookMarkBtnTapped(btn: UIButton)
 }


class HomeTableViewCell: UITableViewCell {

   @IBOutlet weak var bookMarkBtn: UIButton!

   //add delegate var for protocol
   var delegate: HomeTableViewCellDelegate?

   @IBAction func bookMarkBtnAction(_ sender: UIButton) {

    sender.isSelected = !sender.isSelected

    if(sender.isSelected == true)
    {
        sender.setImage(UIImage(named:"favorite_blue"), for: UIControlState.normal)
    }
    else
    {
        sender.setImage(UIImage(named:"favorite_white"), for: UIControlState.normal)
    }

    //set this which button is pressed
    self.delegate?.bookMarkBtnTapped(btn: sender)
   }
}

HomeViewController implement HomeTableViewCellDelegate method

class HomeViewController: HomeTableViewCellDelegate {

     func bookMarkBtnTapped(btn: UIButton) {

 //        here btn is book mark button tapped by user from tableview cell
     }
}
