Try this out for UITableView Section Header.

1. Programatically create headerview

   func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
       let headerView = UIView.init(frame: CGRectMake(0, 0, tblView.bounds.size.width, 50))
       let lblHeader = UILabel.init(frame: CGRectMake(15, 13, tableView.bounds.size.width - 10, 24))
       if section == 0 {
           lblHeader.text = "Image Settings"
       }
       else if section == 1 {
           lblHeader.text = "Personal Settings"
       }
       else {
           lblHeader.text = "Other Settings"
       }
       lblHeader.font = UIFont (name: "OpenSans-Semibold", size: 18)
       lblHeader.textColor = UIColor.blackColor()
       headerView.addSubview(lblHeader)
       headerView.backgroundColor = UIColor(colorLiteralRed: 240.0/255.0, green: 240.0/255.0, blue: 240.0/255.0, alpha: 1.0)
       return headerView
   }
   

2. Height for HeaderView

   func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
       return 50
   }
