UITableViewDiffableDataSource does not work for reordering

I'm trying to use UITableViewDiffableDataSource to implement a UITableView which supports reordering.

Firstly, I set tableView.isEditing = true.

Then I subclassed UITableViewDiffableDataSource in order to override func tableView(_: UITableView, canMoveRowAt _: IndexPath) -> Bool however it does not work.

After that, I also override func tableView(_: UITableView, canEditRowAt _: IndexPath) -> Bool  and the reorder control showed up.

However, the leading delete button cannot be hidden. So I wrote this code:

Code Block 
  override func tableView(_: UITableView,
                          editingStyleForRowAt _: IndexPath) -> UITableViewCell.EditingStyle
  {
    .none // Disable the delete button BUT there's unexpected left indent
  }

Unfortunately, the left indent for the delete still keeps.

So I add this kind of code to disable the leading indent:

Code Block 
cell.shouldIndentWhileEditing = false // Code to disable left indent does not work at all

But it does not work at all.

Anything I can do?

I published all the code for reproduction:
