View table Cells that change colors when scrolling Swift

Question

I am creating an application that uses colored table view tables to categorize other cells. I do this by coloring cells with different colors using if else statements. But for some reason, when I launch the application, the more I look up and down the table view, the more other cells randomly change color. This is the code in my customTableCell class:

@IBOutlet var nameLabel: UILabel?
@IBOutlet var descriptionLabel: UILabel?
@IBOutlet var thumbnailImage: UIImageView!

func configurateTheCell(recipie: Recipie) {
    self.nameLabel?.text = recipie.name
    self.descriptionLabel?.text = recipie.description
    self.thumbnailImage?.image = UIImage(named: recipie.thumbnails)
    if nameLabel!.text == "Instrument"
    {
        backgroundColor = UIColor.orangeColor()
        nameLabel?.textColor = UIColor.blackColor()
    }
    else if nameLabel!.text == "Optional addon"
    {
        backgroundColor = UIColor.cyanColor()
    }

}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    if nameLabel!.text == "Instrument"
    {
        return 20
    }
    else if nameLabel!.text == "Optional addon"
    {
        return 20
    }
    else
    {
        return 100
    }


}

and this is what the application looks like at startup:

against. when the user scrolls a bit:

also, if someone knows how, I would like the color cells to be smaller too, so that the application looks better.

cellForRowAtIndexPath

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier("your identifier", forIndexPath: indexPath)
     if cell.recipie.name == "Instrument"
     {
      backgroundColor = UIColor.orangeColor()
      nameLabel?.textColor = UIColor.blackColor()
     }
    else if cell.recipie.name == "Optional addon"
     {
      backgroundColor = UIColor.cyanColor()
     }
   else{
    backgroundColor = UIColor.whiteColor()
   }
  return cell
 }
