i am trying to implement a paying module to my application in swift 3 with the name mobilepay. When a user on my application has bought a cup of coffee and presses buy with mobilepay, he comes to the mobilepay application, where he buys the cup of coffee. Then he is returned to our application after it does its thing, which comes back with a function that is called in our app delegate (mobilepay themselves asked for this to be placed in app delegate). When we get back to our application we basically get this error when trying run a alert for the viewer saying like "purchase successful.":
MobilePay purchase succeeded: Your have now paid for order with id 123456 and MobilePay transaction id 12345678901234567890 and the amount withdrawn from the card is: 10.0

2017-05-01 09:05:59.033882+0200 Keebin_development_1[262:10533] [App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction
this our code in appdelegate:
func alert(message: String, title: String = "") {
let alertController = UIAlertController(title: title, message: message, preferredStyle: .alert)
let OKAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alertController.addAction(OKAction)
self.window?.rootViewController?.present(alertController, animated: true, completion: nil)
}
func application(_ app: UIApplication, open url: URL, options: [String: Any]) -> Bool {
handleMobilePayPayment(with: url)
return true
}
func handleMobilePayPayment(with url: URL) {
MobilePayManager.sharedInstance().handleMobilePayPayment(with: url, success: {( mobilePaySuccessfulPayment: MobilePaySuccessfulPayment?) -> Void in
let orderId: String = mobilePaySuccessfulPayment!.orderId
let transactionId: String = mobilePaySuccessfulPayment!.transactionId
let amountWithdrawnFromCard: String = "(mobilePaySuccessfulPayment!.amountWithdrawnFromCard)"
print("MobilePay purchase succeeded: Your have now paid for order with id (orderId) and MobilePay transaction id (transactionId) and the amount withdrawn from the card is: (amountWithdrawnFromCard)")
self.alert(message: "You have now paid with MobilePay. Your MobilePay transactionId is (transactionId)", title: "MobilePay Succeeded")
}, error: {( error: Error?) -> Void in
// let dict: [AnyHashable: Any]? = error?.userInfo
// let errorMessage: String? = (dict?.value(forKey: NSLocalizedFailureReasonErrorKey) as? String)
// print("MobilePay purchase failed: Error code '(Int(error?.code))' and message '(errorMessage)'")
// self.alert(message: errorMessage!, title: "MobilePay Error (error?.code as! Int)")
self.alert(message: error as! String)
//TODO: show an appropriate error message to the user. Check MobilePayManager.h for a complete description of the error codes
//An example of using the MobilePayErrorCode enum
//if (error.code == MobilePayErrorCodeUpdateApp) {
// NSLog(@"You must update your MobilePay app");
//}
}, cancel: {(_ mobilePayCancelledPayment: MobilePayCancelledPayment?) -> Void in
print("MobilePay purchase with order id (mobilePayCancelledPayment?.orderId!) cancelled by user")
self.alert(message: "You cancelled the payment flow from MobilePay, please pick a fruit and try again", title: "MobilePay Canceled")
})
}
I have no idea how to solve this issue, it seems the alert is called before the page is loaded properly?
Any help would be greatly appreciated. Thanks in advance, Sebastian.
