Invalid Address in ApplePay with Stripe - ios

Question

I am using Apple Pay with Stripe and it works fine when there is no shipping is available.
When there is a shipping address selected it always gives invalid address error. (It works with Stripe Sandbox Key)
I am using STKPaymentContext API and follow steps from the below link.
https://stripe.com/docs/mobile/ios/basic
in the configuration, I have written this.
let config = STPPaymentConfiguration.shared()
config.requiredShippingAddressFields = [.postalAddress, .phoneNumber,.name]
Not sure what is wrong here.
Here is how it looks.
HERE IS MY CODE
extension CheckoutTableViewController:STPPaymentContextDelegate{
func paymentContext(_ paymentContext: STPPaymentContext, didUpdateShippingAddress address: STPAddress, completion: #escaping STPShippingMethodsCompletionBlock) {
guard
let buyerPostalCode = address.postalCode,
let buyerCountry = address.country,
let productId = self.productDetailsData?.productId
else{
completion(.invalid, nil, nil, nil)
return
}
guard let phone = address.phone, phone.count > 0 else {
completion(.invalid,RatesError.phoneNumberRequired,[],nil)
return
}
var shipmentItem:[String:Any] = [:]
shipmentItem["order_amount"] = self.productCost
shipmentItem["actual_weight"] = 8
shipmentItem["height"] = 7
shipmentItem["width"] = 10
shipmentItem["length"] = 13
shipmentItem["currency"] = "USD"
shipmentItem["destination_postal_code"] = buyerPostalCode
shipmentItem["destination_country_code"] = buyerCountry
shipmentItem["product_id"] = productId
shipmentItem["category"] = "fashion"
enum RatesError:Error,LocalizedError{
case NoDeliveryOptionsFound
case phoneNumberRequired
public var errorDescription: String? {
switch self {
case .NoDeliveryOptionsFound:
return "No couriers are available at the address.\nPlease try with different address."
case .phoneNumberRequired:
return "Please enter phone number."
}
}
}
fetchShippingOptions(forItem: shipmentItem, completionSuccess: {[weak self] (response) in
guard let self = `self` else {
return
}
if
let responseValue = response as? [String:Any],
let rates = responseValue["rates"] as? [[String:Any]]{
self.shippingRates = []
for rate in rates{
if let fullName = rate["courier_display_name"] as? String,
let identifier = rate["courier_id"] as? String,
let amount = rate["shipment_charge_total"] as? Double,
let detail = rate["full_description"] as? String
{
let method = PKShippingMethod()
method.amount = NSDecimalNumber.init(value: amount.currency)
method.identifier = identifier
method.label = fullName
method.detail = detail.replacingOccurrences(of: fullName, with: "")
self.shippingRates.append(method)
}
}
completion(.valid, nil, self.shippingRates, self.shippingRates.first)
}else{
completion(.invalid,RatesError.NoDeliveryOptionsFound,[],nil)
}
}) { (error) in
completion(.invalid,error,[],nil)
}
}
func paymentContextDidChange(_ paymentContext: STPPaymentContext) {
if let paymentOption = paymentContext.selectedPaymentOption {
self.lblPaymentMethod.text = paymentOption.label
} else {
self.lblPaymentMethod.text = "Select Payment"
}
if let shippingMethod = paymentContext.selectedShippingMethod {
if let selectedRate = self.shippingRates.first(where: { (method) -> Bool in
guard let leftValue = method.identifier, let rightValue = shippingMethod.identifier else{
return false
}
return leftValue == rightValue
}){
self.lblAddress.text = selectedRate.label
self.shippingCharges = Double(truncating: selectedRate.amount).currency
self.lblShippingCharges.text = "$\(shippingCharges)"
self.getStripeFees(forAmount: self.productCost + self.shippingCharges)
}
} else {
self.lblAddress.text = "Select Address"
}
self.updateTotalCost()
}
func paymentContext(_ paymentContext: STPPaymentContext, didFailToLoadWithError error: Error) {
let alertController = UIAlertController(
title: "Error",
message: error.localizedDescription,

)
let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: { action in

Answer 1

Finally, I found an error.
Apple calls didUpdateShippingAddress method at the time of payment but it doesn't provide all information for security purposes. So in my case phone number validation was causing that error.
So I removed the below code from that method.
guard let phone = address.phone, phone.count > 0 else {
completion(.invalid,RatesError.phoneNumberRequired,[],nil)
return
}
