cell?.selectionStyle = .none

Answer 1

First of all set a tag to the button which it will be in your case the
row of the IndexPath, add this code in cellForRowAt:
cell?.Trash.addTarget(self, action: #selector(deleting(_:)), for:
.touchUpInside)
cell?.Trash.tag = indexPath.row
You need to modify the deleting() function to be #objc since selectors
after swift 3+ are a must to add that and add the button as param into it:
#objc private func deleting(_ button:UIButton){
// here you got the object
let selectedObject = JSONList[button.tag]
}

Answer 2

use closure to get the tapped buttons cells indexpath.
update the table view cell with ibaction and call the closure whenever tapping on trash button.
class FakeTableCell: UITableViewCell{
var selectedCell: ((UITableViewCell) -> ())?
#IBAction func trashButtonTapped(){
selectedCell?(self)
}
}
then we can get the indexpath of the cell in cell for row for indexpath as follows
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = FakeTableCell()
cell.selectedCell = { selectedCell in
if let ip = tableView.indexPathForRow(at: selectedCell.center){
self.deleteData(with: ip.row)
}
}
return cell
}
func deleteData(with row: Int){
// get the object by JSONList[row]
let item = JSONList[row]
// perform deletion
}
