How to fix delayed data on prepare segue?

Question

My data got delayed 1 time when I want to pass the data in my tableview and pass it to another viewcontroller

i'm using prepare for segue.

now, in order to get the right data i need go back to the table view and press the same row

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "toRequestCorrection"{
            let destinationVC = segue.destination as! RequestCorrectionViewController
            if let indexPath = tableView.indexPathForSelectedRow{
                destinationVC.Shift = self.correction["Shift"].stringValue
                destinationVC.LogDate = self.correction["LogDate"].stringValue
                destinationVC.logIn = self.correction["ActualLogIn"].stringValue
                destinationVC.logOut = self.correction["ActualLogOut"].stringValue
                destinationVC.breakEnd = self.correction["ActualBreakEnd"].stringValue
                destinationVC.breakStart = self.correction["ActualBreakStart"].stringValue
                destinationVC.overTimeIn = self.correction["ActualOverTimeIn"].stringValue
                destinationVC.overTimeOut = self.correction["ActualOverTimeOut"].stringValue
                destinationVC.transactionStatusID = self.correction["TransactionStatusID"].intValue
            }
        }
    }

it's should pass the data on the row right after i pressed the row

Additionally, you do not have to use segue, you can instantiate your view controller inside didSelectRowAt method with following code without prepareForSegue.

EDIT: You didn't indicate it's an async task. So, I am using Alamofire with completion handler. I think it will be useful for you.

typealias yourCompletionHandler = (Data?, _ message: String?, _ errorStatusCode: Int?) -> Void
func yourAsyncTask(handler: @escaping yourCompletionHandler) {
    let parameters: [String: Any] = ["unitId": 4124]
    let url = ""
    Alamofire.request(url, method: .get, parameters: parameters)
        .responseObject { (response: DataResponse<BaseListResponseParser<YourModel>>) in
            switch response.result {
            case .success:
                if let result = response.result.value {
                  handler(result.listItems, nil, nil)
                }
            case .failure(let error):
                print(error)
            }
    }
} 


yourAsyncTask { [weak self] (yourModel, error, _) in
        DispatchQueue.main.async {
            guard let destination = UIStoryboard(name: "Main", bundle: nil)
                .instantiateViewController(withIdentifier: "ViewControllerId") as? RequestCorrectionViewController else { return }
            destination.Shift = yourModel.shift
            navigationController?.pushViewController(destination, animated: true)
        }
    }

Using that way you do not need to create segue or prepareForSegue method.
