ios – Getting an error “try and insert row 4 into part 1, however there are solely 4 rows in part 1 after the replace” whereas drop and drag

I am attempting to implement drop and drag, however getting an error: try and insert row 4 into part 1, however there are solely 4 rows in part 1 after the replace

I get this error, when attempt to drop merchandise from Reminder to my tableView.
I’ve this code im my ViewController:

extension ProfileViewController: UITableViewDropDelegate {
    func tableView(_ tableView: UITableView, performDropWith coordinator: UITableViewDropCoordinator) {
        let destinationIndexPath = IndexPath(row: tableView.numberOfRows(inSection: 1), part: 1)
        let merchandise = coordinator.gadgets[0]
        
        swap coordinator.proposal.operation {
        case .copy:
            print("Copying...")
            let itemProvider = merchandise.dragItem.itemProvider
            
            itemProvider.loadObject(ofClass: NSString.self) { string, error  in
                if (string as? String) != nil {
                    let fasting = Fasting(autor: "Writer", description: "Description", picture: UIImage(named: "регби") ?? UIImage(), numberOfLikes: 0, numberOfviews: 0)
                    self.addGeocache(fasting, at: destinationIndexPath.row)
                    DispatchQueue.fundamental.async {
                        tableView.insertRows(at: [destinationIndexPath], with: .computerized)
                    }
                }
        }
        default:
            return
        }
    }

Right here I create numberOfRows im my tableView:

func tableView(_ tableView: UITableView, numberOfRowsInSection part: Int) -> Int {
        if part == 0 {
            return 1 
        } else {
            return Circulate.sections.fasting.rely
        }
    }

That is my array of parts in part 1:

struct Circulate {
    
    static let sections = FastingSections(
            fasting: [
                Fasting(autor: "Gustav",
                        description: "Today i did eat this",
                        image: UIImage(named: "эко-мороженое 1")!,

                    ]
                    )
}
