Implement Apple pay in swift 5

During the presentation on the 9th of September 2014, Apple introduced Apple Pay — its own system of mobile payments.

Apple pay allows iPhone 6 and iPhone 6+ users, as well as those who have new versions of Apple Watch easily shop online now, and benefit from apple pay app integration as well as make payments with the help of NFC (Near Field Communication) Technology. Touch ID or Face ID technologies are used for payment authorization.

How to Set Up Apple Pay in The App

To set up your environment to implement Apple Pay in your apps, you must complete these steps:

Create a Merchant ID
Configure Apple Pay capabilities in Xcode for your project
Create a sandbox user in iTunes Connect
Add a test card
Create a payment request in your project
Handle the result

Step 1: Create a Merchant ID from your Apple Developer Account.

Steps 2: Configure Apple Pay capabilities in Xcode for your project

Steps 3: Create a sandbox user in iTunes Connect

Steps 4: Add a test card in the account

Please click here for demo card details.

Steps 5: Create a payment request for the project.
First, create UI For apple pay.

Import the PassKit Library in ViewController

import PassKit

1	import PassKit

Create a Payment Request in the ViewController

private var paymentRequest: PKPaymentRequest = {
        let request = PKPaymentRequest()
        request.merchantIdentifier = "merchant.com..."
        request.supportedNetworks = [.visa, .masterCard,.amex,.discover]
        request.supportedCountries = ["UA"]
        request.merchantCapabilities = .capability3DS
        request.countryCode = "UA"
        request.currencyCode = "UAH"
        request.paymentSummaryItems = [PKPaymentSummaryItem(label: "App test", amount: 10.99)]
        return request
    }()

private var paymentRequest: PKPaymentRequest = {

let request = PKPaymentRequest()

request.merchantIdentifier = "merchant.com..."

request.supportedNetworks = [.visa, .masterCard,.amex,.discover]

request.supportedCountries = ["UA"]

request.merchantCapabilities = .capability3DS

request.countryCode = "UA"

request.currencyCode = "UAH"

request.paymentSummaryItems = [PKPaymentSummaryItem(label: "App test", amount: 10.99)]

return request

}()

Handle the Apple Pay button action and make payment request

@IBAction func purchase(_ sender: Any?) {
        if let controller = PKPaymentAuthorizationViewController(paymentRequest: paymentRequest) {
            controller.delegate = self
            present(controller, animated: true, completion: nil)
        }
    }

@IBAction func purchase(_ sender: Any?) {

if let controller = PKPaymentAuthorizationViewController(paymentRequest: paymentRequest) {

controller.delegate = self

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

}

Steps 6: Handle the result

Confirm the PKPaymentAuthorizationViewControllerDelegate in the View Controller

extension ViewController: PKPaymentAuthorizationViewControllerDelegate {
 
    func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void) {
        completion(PKPaymentAuthorizationResult(status: .success, errors: nil))
    }
 
    func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
 
}

extension ViewController: PKPaymentAuthorizationViewControllerDelegate {

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

completion(PKPaymentAuthorizationResult(status: .success, errors: nil))

}

func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {

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

}

Now run your app.

In this way, you can integrate Apple pay in your app. I hope you understand the whole process. If you have any queries or suggestions please comment below.

Thank you

Yes, you can test but need to change the Region to the United States or other regions from the device setting.

After payment is done paymentAuthorizationViewControllerDidFinish method will be called, so you can put your condition inside this method.

If we send -> completion(PKPaymentAuthorizationResult(status: .success, errors: nil)) , then the payment gets charged

You have to implement any third party payment gateway like stripe, which collect payment from Applypay and return your success and failure status.According to this result, you have to manage the completion
