You could subclass UITableViewCell and add a button, here is an example class:

import UIKit

private let DWWatchlistAddSymbolCellAddSymbolButtonLeftMargin: CGFloat = 15

class DWWatchlistAddSymbolCell: UITableViewCell {

  private(set) var addSymbolButton:UIButton

  init(reuseIdentifier:String?, primaryTextColor:UIColor) {
    self.addSymbolButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
    super.init(style:UITableViewCellStyle.Default, reuseIdentifier:reuseIdentifier)
    selectionStyle = UITableViewCellSelectionStyle.None
    backgroundColor = UIColor.clearColor()
    imageView!.image = UIImage(named:"PlusIcon")!
    addSymbolButton.setTitle("Add Symbol", forState:UIControlState.Normal)
    addSymbolButton.setTitleColor(primaryTextColor, forState:UIControlState.Normal)
    addSymbolButton.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left
    addSymbolButton.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
    contentView.addSubview(addSymbolButton)
  }

  required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }

  // MARK: Layout

  override func layoutSubviews() {
    super.layoutSubviews()
    addSymbolButton.frame = contentView.frame
    let imageViewFrame = imageView!.frame
    let imageViewMaxX = imageViewFrame.origin.x + imageViewFrame.size.width
    let addSymbolButtonX = imageViewMaxX + DWWatchlistAddSymbolCellAddSymbolButtonLeftMargin
    addSymbolButton.contentEdgeInsets = UIEdgeInsetsMake(0, addSymbolButtonX, 0, 0);
  }
}

You can see the "Add Symbol" button at the bottom:

                                       

When you're returning the cell for the UITableViewDataSource, make sure to set the target for the button:

private func addButtonCell(tableView: UITableView) -> UITableViewCell {
  var cell:DWWatchlistAddSymbolCell? = tableView.dequeueReusableCellWithIdentifier(kDWWatchlistViewControllerAddButtonCellReuseIdentifier) as? DWWatchlistAddSymbolCell
  if (cell == nil) {
    cell = DWWatchlistAddSymbolCell(reuseIdentifier:kDWWatchlistViewControllerAddButtonCellReuseIdentifier, primaryTextColor:primaryTextColor)
  }
  cell!.addSymbolButton.addTarget(self,
    action:Selector("didPressAddSymbolButton"),
    forControlEvents:UIControlEvents.TouchUpInside)
  return cell!
}
