UIContextualAction with icon AND clear background in swift

Question

I use the following code

  let deleteAction =
   UIContextualAction(style: .normal, title: ""){ (action, sourceView, completionHandler) in

            self.dataManager.items.remove(at: indexPath.row)
            self.itemCardTableView.deleteRows(at: [indexPath], with: .automatic)
            completionHandler(true)
    }

let deleteResize = #imageLiteral(resourceName: "delete72").resizeImage(withSize: CGSize(width: 50, height: 50), scaleMode: .contentAspectFill)
    deleteAction.backgroundColor = UIColor.white
    deleteAction.backgroundColor = UIColor(patternImage: deleteResize!)

image is repeated. This is not what I want

How to fix it

show your code of `UISwipeActionsConfiguration` – Anbu.Karthik Jun 19 '18 at 06:00 — Anbu.Karthik, Jun 19 '18 at 06:00
try with `scaleMode: .contentAspectFit` – Anbu.Karthik Jun 19 '18 at 06:01 — Anbu.Karthik, Jun 19 '18 at 06:01
scaleMode: .contentAspectFit is not working – Josh Jun 19 '18 at 06:25 — Josh, Jun 19 '18 at 06:25
Please do not post image of your code, post your code! – Olcay Ertaş Jun 19 '18 at 07:03 — Olcay Ertaş, Jun 19 '18 at 07:03

Do not use UIColor(patternImage: deleteResize!), instead use the image property of the UIContextualAction instance.

To get a truly .clear background has been solved here https://stackoverflow.com/a/51939297/5058116, but appears very messy ...

Can you set background color with alpha = 0.

      let deleteAction = UIContextualAction(style: .normal, title:  "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
                  //TODO: 
        })
      deleteAction.backgroundColor = .white.withAlphaComponent(0)
