Drag & Drop from TableView to Another View in Swift

Currently I does't have the time to test the code, but it should be enough to make sense.... You can do something like this:

class ViewController: UIViewController, UITableViewDataSource {

    private var dragView: UIView?
    @IBOutlet weak var dropZone: UIView!

    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)

        let lpGestureRecognizer: UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: #selector(didLongPressCell))
        cell.contentView.addGestureRecognizer(lpGestureRecognizer)

        return cell
    }

    func didLongPressCell (recognizer: UILongPressGestureRecognizer) {
        switch recognizer.state {
        case .Began:
            if let cellView: UIView = recognizer.view {
                cellView.frame.origin = CGPointZero
                dragView = cellView
                view.addSubview(dragView!)
            }
        case .Changed:
            dragView?.center = recognizer.locationInView(view)
        case .Ended:
            if (dragView == nil) {return}

            if (CGRectIntersectsRect(dragView!.frame, dropZone.frame)) {
                if let cellView: UIView = (dragView?.subviews[0])! as UIView {
                    cellView.frame.origin = CGPointZero
                    dropZone.addSubview(cellView)
                }

                dragView?.removeFromSuperview()
                dragView = nil

                //Delete row from UITableView if needed...
            } else {
                //DragView was not dropped in dropszone... Rewind animation...
            }
        default:
            print("Any other action?")
        }
    }

}

Update on comment:

sure, one possibility would be to tag the fields... like this:

private let imageViewTag: Int = 997
private let textLabelTag: Int = 998
private let detailTtextLabelTag: Int = 999

//...

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    //...
    cell.imageView?.tag = imageViewTag
    cell.textLabel?.tag = textLabelTag
    cell.detailTextLabel?.tag = detailTtextLabelTag
    //...

}

func didLongPressCell (recognizer: UILongPressGestureRecognizer) {
    //...
    case .Ended:
    let cellImageView: UIImageView? = recognizer.view?.viewWithTag(imageViewTag) as? UIImageView
    let cellTextLabel: UITextField? = recognizer.view?.viewWithTag(textLabelTag) as? UITextField
    let cellDetailTextLabel: UITextField? = recognizer.view?.viewWithTag(detailTtextLabelTag) as? UITextField
    //...
}
