NSURL issue in createRequest() function of PayUCreateRequest in Payu Swift integration

Question

I am integrating Payu in iOS app with Swift language. Since Payu has not provided iOS SDK and documentation, so the links that I have used are Integrating PayU Money Gateway iOS Swift and How to integrate PayU Money in swift . But I am facing same issue in both integrations.

Issue : [NSURL init] called; this results in an NSURL instance with an empty URL string. Please use one of the documented NSURL initialization methods instead (initWithString:, initFileURLWithPath:, etc.). This message shown only once.

The code I am using (from link 1) :

 import UIKit

class ViewController: UIViewController {

    @IBAction func onTapBtnPay(_ sender: UIButton) {
        continueWithCardPayment()
        createRequest.createRequest(withPaymentParam: paymentParamForPassing,forPaymentType: PAYMENT_PG_PAYU_MONEY , withCompletionBlock: {(request, postParam , error) in
            if error == nil {
                print("Success")
            }
            else
            {
                print("Error data : \(error.debugDescription)")
                print("Failure")
            }
        })
    }

    var paymentParamForPassing = PayUModelPaymentParams()
    var webServiceResponse: PayUWebServiceResponse = PayUWebServiceResponse()
    var createRequest: PayUCreateRequest = PayUCreateRequest()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func continueWithCardPayment()  {

        paymentParamForPassing.key = "0MQaQP"
        paymentParamForPassing.transactionID = "Ywism0Q9XC88qvy";

        paymentParamForPassing.email = "email@testsdk1.com";
        paymentParamForPassing.userCredentials = "ra:ra";
        paymentParamForPassing.phoneNumber = "1111111111";

The another code (from link 2) I am using is :

    import UIKit

class ViewController: UIViewController {

    @IBAction func onTapBtnPay(_ sender: UIButton) {
        continueWithCardPayment()
    }


    let paymentParam: PayUModelPaymentParams  = PayUModelPaymentParams()
    var hashes :PayUModelHashes  = PayUModelHashes()
//    let PUSAhelper:PUSAHelperClass = PUSAHelperClass()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func continueWithCardPayment()  {

        paymentParam.key = "smsplus"
        paymentParam.transactionID = "umangtxn123"
        paymentParam.amount = "100.0"
        paymentParam.productInfo = "Nokia"
        paymentParam.surl = "https://www.payumoney.com/mobileapp/payumoney/success.php"
        paymentParam.furl = "https://www.payumoney.com/mobileapp/payumoney/failure.php"
        paymentParam.firstName = "Umang"
        paymentParam.email = "umangarya336@gmail.com"
        paymentParam.environment = ENVIRONMENT_MOBILETEST
        paymentParam.udf1 = "udf1"
        paymentParam.udf2 = "udf2"
        paymentParam.udf3 = "udf3"
        paymentParam.udf4 = "udf4"
        paymentParam.udf5 = "udf5"
        paymentParam.offerKey = ""
        // Set this property if you want to give offer:
        paymentParam.userCredentials = ""

        PUSAHelperClass.generateHash(fromServer: self.paymentParam) { (hashes, errorString) in
            self.hashes = hashes ?? PayUModelHashes()
            self.paymentParam.hashes = hashes
            self.callPaymentGateway()
        }
    }

    func callPaymentGateway()  {

        let webServiceResponse :PayUWebServiceResponse = PayUWebServiceResponse()

        webServiceResponse.getPayUPaymentRelatedDetail(forMobileSDK: paymentParam) { (paymentDetail, errString, extraParam) in

            if errString == nil {

                let storyboard = UIStoryboard(name: "Main", bundle: nil)
                let payOptionVC = storyboard.instantiateViewController(withIdentifier: "PUUIPaymentOptionVC") as! PUUIPaymentOptionVC

                payOptionVC.paymentParam = self.paymentParam
                payOptionVC.paymentRelatedDetail = paymentDetail

                DispatchQueue.main.async {
                    NotificationCenter.default.addObserver(self, selector: #selector(self.paymentResponseReceived(notify:)), name: NSNotification.Name(rawValue: kPUUINotiPaymentResponse), object: nil)
                    self.navigationController?.pushViewController(payOptionVC, animated: true)
                }
                              }
            }
            else{
                print("Failed to proceed for payment : \(errString)")
            }
        }
    }

    @objc func paymentResponseReceived(notify:NSNotification) {
        print(notify)
    }

}

I have resolved the issue.

You can use the blog on PayU Integration in iOS using swift link.
