Introduction I previously never had a chance to work with GraphQL. I was excited to learn when to apply this technology, what tools I can use, and how I can implement it. Here’s what I found: For testing, I used the Star Wars GraphQL API with AllFilmsQuery: query AllFilmsQuery { allFilms { films { title director created producers releaseDate } } } I requested allFilms with title, director, created, producers, and releaseDate information. ...
Introduction I was eager to learn about securing user data using Keychain and biometric authentication. Here are a few steps I found: Caveats You can test accessing Keychain data using Touch ID and Face ID only on a real device.

Here are a few steps on how I did it: First Step You need to add Apple Pay capability to your project. You will need to Register a Merchant ID. I will skip this step; you can find info by following this link Setting up Apple Pay. Second Step You will need to import PassKit and create PKPaymentRequest to interact with PKPaymentAuthorizationController and PKPaymentAuthorizationControllerDelegate. func initiateApplePay() { // Create payment request let paymentRequest = PKPaymentRequest() paymentRequest.merchantIdentifier = "your_merchant_identifier" paymentRequest.countryCode = "US" paymentRequest.currencyCode = "USD" paymentRequest.supportedNetworks = [.visa, .masterCard, .amex] paymentRequest.merchantCapabilities = .threeDSecure // Add payment items from cart for item in cartItems { let paymentItem = PKPaymentSummaryItem(label: item.name, amount: item.price) paymentRequest.paymentSummaryItems.append(paymentItem) } // Add total amount let totalItem = PKPaymentSummaryItem(label: "Total", amount: totalAmount) paymentRequest.paymentSummaryItems.append(totalItem) // Present Apple Pay sheet let paymentController = PKPaymentAuthorizationController(paymentRequest: paymentRequest) paymentController.delegate = self paymentController.present(completion: nil) } Third Step Add UI and connect it with the view model. ...
Introduction I have been looking for information about implementation details of integration testing. I found a lot of information, but it was theoretical and all information looked the same. I did not find a meaningful example, so I tried to come up with my own definition and sample. Integration testing means testing the behavior between modules or views to ensure they work as expected after user actions. There are two ways of conducting integration testing: The first is by unit tests, where you try to test the flowing data between view models. The second is UI tests, where you try to test if the UI items exist and navigation works correctly. I will focus on testing the flowing data between view models. ...
