Instance Method


Called when dragged content enters the table view's bounds rectangle.


optional func tableView(_ tableView: UITableView, dropSessionDidEnter session: UIDropSession)



The table view that is now the potential target of the drop.


The drop session object containing information about the data being dragged.


The table view calls this method when dragged content first enters its bounds rectangle. This method is not called again until the dragged content exits the table view's bounds (triggering a call to the tableView(_:dropSessionDidExit:) method) and enters again.

Use this method to perform any one-time setup associated with tracking dragged content over the table view.
