Could you tell me, how to add custom image to delete button when swipe cell on UITableview?

As of iOS 8.0 there's an easy way to customize the list of buttons that appear when the user swipes from right to left: editActionsForRowAt . Return an array of UITableViewRowAction objects that have titles and styles (and also background colors if you want to customize their appearance), and iOS does the rest.
When you want to handle deleting, you have to do three things: first, check that it's a delete that's happening and not an insert (this is down to how you use the UI); second, delete the item from the data source you used to build the table; and third, call deleteRows(at:) on your table view.
A view that presents data using rows in a single column. iOS 2.0+ iPadOS 2.0+ Mac Catalyst 13.1+ tvOS 9.0+
search you need function "editActionsForRowAtIndexPath", where you create scope of actions. You need to set UIImage to backgroundColor of UITableViewRowAction.
let someAction = UITableViewRowAction(style: .Default, title: "") { value in
println("button did tapped!")
}
someAction.backgroundColor = UIColor(patternImage: UIImage(named: "myImage")!)
There's this UITableView delegate function you can make use of:
@available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .normal, title: "", handler: {a,b,c in
// example of your delete function
self.YourArray.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .automatic)
})
deleteAction.image = UIImage(named: "trash.png")
deleteAction.backgroundColor = .red
return UISwipeActionsConfiguration(actions: [deleteAction])
}
PS: Personally, I think icon size 32 is the best
