Answer 1

For TableView Height adjustment automatically with its content size use this in ViewController class.

//constraintTableViewHeight :- tableview height constraint 

override func viewWillLayoutSubviews() {
    super.updateViewConstraints()
    self.constraintTableViewHeight.constant = self.tableView.contentSize.height
}

and also add this

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    self.viewWillLayoutSubviews()
}

This code easily adjust tableview height automatically with its content size.
