Good afternoon al
Obs: I use the Rechibility class to check if the user internet is connected or not but in this case the class verify the internet but i dont receive the information from apple. Just in this case
I created a payment system and it works fine, however there is a case that it is crashing which is:
1: User enters app without internet connection (Wi-Fi or 4G) 2: User tries to buy the app offline and gets into the purchase viewcontroller 3: Press the iphone HOME button and then connect the Wi-Fi or 4G 4: After return to the app and press the button to purchase again and the crash appear
This only happens in this situation, in the other test cases I did not receive any errors.
I can not see why this error occurred.
Below is my code and images about the error.
My current code:

import StoreKit
protocol IAPManagerDelegate
{
func managerDidRestorePurchases()
}

var products:NSArray!
//Load product identifiers for store usage
func setupInAppPurchases()
{
self.validateProductIdentifiers(self.getProductIdentifiersFromMainBundle())
SKPaymentQueue.default().add(self)
}
//Get product identifiers
func getProductIdentifiersFromMainBundle() -> NSArray
{
var identifiers = NSArray()
if let url = Bundle.main.url(forResource: "iap_product_ids", withExtension: "plist")
{
identifiers = NSArray(contentsOf: url)!
}
return identifiers
}
//Retrieve product information
func validateProductIdentifiers(_ identifiers:NSArray)
{

{
print("Enter")
let productIdentifiers = NSSet(array: identifiers as [AnyObject])
