Apple Pay works on simulator but not on device

Question

I am able to display Apple Pay view controller on simulator but not on device.

Entitlement added and certificate installed.

class ViewController: UIViewController, PKPaymentAuthorizationViewControllerDelegate {

var paymentRequest: PKPaymentRequest! 

override func viewDidLoad() {
    super.viewDidLoad()

}


func rydes(shipping: Double) -> [PKPaymentSummaryItem] {

    let ryde = PKPaymentSummaryItem(label: "Your Fare", amount: 1.00)
    let discount = PKPaymentSummaryItem(label: "Discount", amount: -0.00)
    let shipping = PKPaymentSummaryItem(label: "Shipping", amount: NSDecimalNumber(string: "\(shipping)"))
    let subTotal = ryde.amount.adding(discount.amount)
    let total = PKPaymentSummaryItem(label: "rydes", amount: subTotal)

    return [ryde, discount, shipping, total]

} // rydes() func


    func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didSelect shippingMethod: PKShippingMethod, completion: @escaping (PKPaymentAuthorizationStatus, [PKPaymentSummaryItem]) -> Void) {

        completion(PKPaymentAuthorizationStatus.success, rydes(shipping: Double(shippingMethod.amount)))

    } // paymentAuthorizationViewController( didSelectShippingMethod )



    func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {

        completion(PKPaymentAuthorizationStatus.success)

    } // paymentAuthorizationViewController( didAuthorizePayment )



    func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {

        controller.dismiss(animated: true, completion: nil)

    } // paymentAuthorizationViewControllerDidFinish()


@IBAction func applePayPressed(_ sender: Any) {


    print("enable apple pay")

    // send user to Apple Pay to make payment

    let paymentNetworks = [PKPaymentNetwork.visa, .masterCard, .interac, .discover, .amex]
    let merchantId = "merchant.com.xxx"


    if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: paymentNetworks) {

        paymentRequest = PKPaymentRequest()
        paymentRequest.currencyCode = "CAD"
        paymentRequest.countryCode = "CA"
        paymentRequest.merchantIdentifier = merchantId
        paymentRequest.supportedNetworks = paymentNetworks
        paymentRequest.merchantCapabilities = .capability3DS
        paymentRequest.requiredShippingAddressFields = [.all]
        paymentRequest.paymentSummaryItems = self.rydes(shipping: 0.00)

        // . . .  shipping - not really needed

        let samedayShipping = PKShippingMethod(label: "Same Day", amount: 12.99)
        samedayShipping.detail = "Guaranteed same day delivery."
        samedayShipping.identifier = "sameday"

        let twodayShipping = PKShippingMethod(label: "Two Day", amount: 4.99)
        twodayShipping.detail = "Guaranteed within two days."
        twodayShipping.identifier = "twoday"

        let freeShipping = PKShippingMethod(label: "Same Day", amount: 0.00)
        freeShipping.detail = "Guaranteed same day."
        freeShipping.identifier = "freeShipping"

        paymentRequest.shippingMethods = [samedayShipping, twodayShipping, freeShipping]

        // . . .  shipping - not really needed

        let applePayVC = PKPaymentAuthorizationViewController(paymentRequest: paymentRequest)
        applePayVC.delegate = self
        self.present(applePayVC, animated: true, completion: nil)

    }  else {

        print("Tell the user they need to set up Apple Pay!")
    }

} // applePayPressed func ACTION

}

The above code just returns this line - Tell the user they need to set up Apple Pay!

I am using a iPhone 6s as the device and Apple Pay and Wallet are enabled with a valid debit card and credit card. I am from Canada, so I am in a valid region.

Edited Code

class ViewController: UIViewController, PKPaymentAuthorizationViewControllerDelegate {

var paymentRequest: PKPaymentRequest! // apple pay

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}


func rydes() -> [PKPaymentSummaryItem] {

    let ryde = PKPaymentSummaryItem(label: "Your Fare", amount: 1.00)
    let subTotal = ryde.amount
    let total = PKPaymentSummaryItem(label: "rydes", amount: subTotal)

    return [ryde, total]

} // rydes() func



    func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {

        completion(PKPaymentAuthorizationStatus.success)

    } // paymentAuthorizationViewController( didAuthorizePayment )



    func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {

        controller.dismiss(animated: true, completion: nil)

    } // paymentAuthorizationViewControllerDidFinish()


@IBAction func applePayPressed(_ sender: Any) {

    print("enable apple pay")

    // send user to Apple Pay to make payment

    let paymentNetworks = [PKPaymentNetwork.visa, .masterCard, .interac, .discover, .amex]
    let merchantID = "merchant.com.xxx"

    if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: paymentNetworks) {
        paymentRequest = PKPaymentRequest()
        paymentRequest.currencyCode = "CAD"
        paymentRequest.countryCode = "CA"
        paymentRequest.merchantIdentifier = merchantID
        paymentRequest.supportedNetworks = paymentNetworks
        paymentRequest.merchantCapabilities = .capability3DS
        paymentRequest.requiredShippingAddressFields = [.all]
        paymentRequest.paymentSummaryItems = self.rydes()

        let applePayVC = PKPaymentAuthorizationViewController(paymentRequest: paymentRequest)
        applePayVC.delegate = self
        self.present(applePayVC, animated: true, completion: nil)

    }  else {

        print("Tell the user they need to set up Apple Pay!")
    }

} // applePayPressed func ACTION

}

Same issue I face during enable of Apple Pay to my application. Make sure you have entered all the valid shipping, service and total payment value inside PKPayment​Summary​Item.

Also total payment value should be greater that 0.0 to show the payment gate way view. If any of the value is 0.0 then don't add as SummaryItem.

Code for Valid PKPaymentSummaryItem:

{
// 12.75 subtotal
NSDecimalNumber *subtotalAmount = [NSDecimalNumber decimalNumberWithMantissa:1275
 exponent:-2 isNegative:NO];
self.subtotal = [PKPaymentSummaryItem summaryItemWithLabel:@"Subtotal" amount:subtotalAmount];

// 2.00 discount
NSDecimalNumber *discountAmount = [NSDecimalNumber decimalNumberWithMantissa:200 exponent:-2 isNegative:YES];
self.discount = [PKPaymentSummaryItem summaryItemWithLabel:@"Discount" amount:discountAmount];

// 12.75 - 2.00 = 10.75 grand total
NSDecimalNumber *totalAmount = [NSDecimalNumber zero];
totalAmount = [totalAmount decimalNumberByAdding:subtotalAmount];
totalAmount = [totalAmount decimalNumberByAdding:discountAmount];
self.total = [PKPaymentSummaryItem summaryItemWithLabel:@"My Company Name" amount:totalAmount];
self.summaryItems = @[self.subtotal, self.discount, self.total];
request.paymentSummaryItems = self.summaryItems;
}

This will try to fix your above issue.

Edit: Just remove below code and check it again or put check condition if value for discount or shipping is greater that 0.0 then you can send shipping and discount as summary item:

    let ryde = PKPaymentSummaryItem(label: "Your Fare", amount: 1.00)
//change some value here:
    let discount = PKPaymentSummaryItem(label: "Discount", amount: -0.00)
    let shipping = PKPaymentSummaryItem(label: "Shipping", amount: NSDecimalNumber(string: "\(shipping)"))
Make sure your subtotal or total is greater that 0.0.
    let subTotal = ryde.amount.adding(discount.amount)
    let total = PKPaymentSummaryItem(label: "rydes", amount: subTotal)
