From all the other answers on stackoverflow, I have not found the answer to this particular question.

I am using SKReceiptRefreshRequest to restore a purchase. I am using a sandbox account. I have the following code:

let request = SKReceiptRefreshRequest()  



request.delegate = self  



request.start()  

When the result is a call to requestDidFinish of the SKRequestDelegate protocol. The request I get back has nil for its receiptProperties property. How do I interpret that? The documentation (Refreshing the App Receipt) says to check the receipt, but there appears to be nothing to check.

Here is my code when I assume that getting a request back with nil receiptProperties mean that I received back a receipt.

extension SettingsTableViewController: SKRequestDelegate {



    func requestDidFinish(_ request: SKRequest) {



        print("requestDidFinish")



        print("request=", request)



        if let receiptRefreshRequest = request as? SKReceiptRefreshRequest {



            print("receipt properties=", receiptRefreshRequest.receiptProperties as Any)



        }



        if iCloudAvailable() {



            ubiquitousKeyValueStore.set(true, forKey: UbiquitousKeys.iMessageExtension)



            let alertMessage = "iMessage Saved Messages has been restored."



            let alert = UIAlertController(title: nil, message: alertMessage, preferredStyle: .alert)



            let actionOK = UIAlertAction(title: "OK", style: .cancel, handler: nil)



            alert.addAction(actionOK)



            present(alert, animated: true, completion: nil)



        }



    }



    func request(_ request: SKRequest, didFailWithError error: Error) {



        print("requst(_:didFailWithError:)")



        if let receiptRefreshRequest = request as? SKReceiptRefreshRequest {



            print("receipt properties=", receiptRefreshRequest.receiptProperties as Any)



        } else {



            print("request=", request)

        }



        print("error=", error)



        let alertMessage = "There are no purchases to restore."



        let alert = UIAlertController(title: nil, message: alertMessage, preferredStyle: .alert)



        let actionOK = UIAlertAction(title: "OK", style: .cancel, handler: nil)



        alert.addAction(actionOK)



        present(alert, animated: true, completion: nil)



    }



}

I found this webpage with the answer. Apple's documentation didn't show this where it was needed.

"Restoring non-consumable IAPs in iOS" at upbeat.it

func validateReceipt() {

    let recURL = Bundle.main.appStoreReceiptURL!

    let contents = NSData(contentsOf: recURL)

    let receiptData = contents!.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))

    print(receiptData)

    let requestContents = ["receipt-data" : receiptData]

    print(requestContents)

    let requestData = try? JSONSerialization.data(withJSONObject: requestContents, options: )

    print(requestData)

    let serverURL = "https://sandbox.itunes.apple.com/verifyReceipt" // TODO:change this in production with https://buy.itunes.apple.com/verifyReceipt

    let url = NSURL(string: serverURL)

    let request = NSMutableURLRequest(url: url! as URL)

    request.httpMethod = "POST"

    request.httpBody = requestData

    let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in

        guard let data = data, error == nil else {

            self.notifyReceiptResult(false)

            return

        }

        do {

            let json = try JSONSerialization.jsonObject(with: data, options:) as? [String: Any]

            if let receipt = json?["receipt"] as? [String: AnyObject],

                let inApp = receipt["in_app"] as? [AnyObject] {

                print(inApp)

                if (inApp.count > 0) {

                    self.notifyReceiptResult(true)

                } else {

                    self.notifyReceiptResult(false)

                }

            }

        }

        catch let error as NSError {

            print(error)

            self.notifyReceiptResult(false)

        }

    })

    task.resume()
