Corner Radius of UITableViewCell Being Reset when Editing

I have a UITableView that has a list of UITableViewCells with custom corner radii. When swiping to edit, e.g. delete/insert, the corner radius is reset back to 0.

I've tried to set the corner radius while editing:

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
    guard let cell = tableView.cellForRow(at: indexPath) as? HabitTableViewCell else { return }
    cell.layer.cornerRadius = 13
    if editingStyle == .delete {
        controller.delete(habit: frc.object(at: indexPath))
    }
}

I've also tried implementing willBeginEditingRowAt in a similar way to try to get the corner radius to stay set. The last thing I tried was creating a custom UIContextualAction in trailingSwipeActionsConfigurationForRowAt, but it doesn't change anything.

There was a similar question asked about four years ago, but no conclusive solution was ever found. Any help or insight is appreciated!

You need to set corner radius and border to contentView.

cell.contentView.layer.cornerRadius = 13

Add this code to awakeFromNib or layoutSubviews method of UITableViewCell class.

override func awakeFromNib() {
    super.awakeFromNib()
    self.contentView.layer.cornerRadius = 13

    // Your border code here (set border to contentView)
    self.contentView.layer.borderColor = UIColor.blue.cgColor
    self.contentView.layer.borderWidth = 3
}
