        cons.bottom.equalTo(self).inset(15)

Answer 1

I solve this problem By adding my View Into TableviewCell content view

 self.contentView.addSubview(stack)
 phone.delegate = self
 password.delegate = self
 stack.snp.makeConstraints { (cons) in
        cons.left.right.equalTo(self.contentView).inset(25)
        cons.centerY.equalTo(self.contentView)
        cons.height.equalTo(230)
        cons.bottom.equalTo(self.contentView).inset(15)
 }
 self.contentView.backgroundColor = .white

and I return this view from tableviewHeaderContent

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let head = tableView.dequeueReusableCell(withIdentifier: headerid) as! ProfileLoginTableViewCell
        return head.contentView
    }
