使用 Core Data 在 UITableViewController 中保存重新排序的单元格

Question

I'm looking for simple implementation of saving reordering cells in UITableViewController with Core Data.

Now I'm using the default function for reorder cells:

var timers: [Timers] = []

    override func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {

    let movedObject = timers[sourceIndexPath.row]
    timers.remove(at: sourceIndexPath.row)
    timers.insert(movedObject, at: destinationIndexPath.row)


    }

How I can implement Core Data for saving cell ordering feature?

You need to re-save the array again every leave of that vc say inside deinit
