The skip-stripe framework is available at https://github.com/skiptools/skip-stripe.git, which can be checked out and tested with skip test once Skip is installed.

SkipStripe

• Testing

This is a free Skip Swift/Kotlin framework that contains integration with the Stripe SDK’s ‘Mobile Payment Element for iOS and Android.

Usage

The API includes a StripePaymentButton which is created using a StripePaymentConfiguration.

For information on how to initialize the configuration object, see the Stripe documentation for iOS and Android.

import SkipStripe

struct PaymentButton: View {
    let paymentConfig = StripePaymentConfiguration(
        publishableKey: "PUBLISHABLE_KEY",
        merchantName: "Merchant, Inc.",
        customerID: "CUSTOMER_ID",
        ephemeralKeySecret: "EPHEMERAL_KEY_SECRET",
        clientSecret: "CLIENT_SECRET"
    )

    var body: some View {
        StripePaymentButton(configuration: paymentConfig, completion: paymentCompletion) {
            Text("Pay Now!")
        }
        .buttonStyle(.borderedProminent)
    }

    func paymentCompletion(result: StripePaymentResult) {
        switch result {
        case .completed:
            logger.log("Payment completed")
        case .canceled:
            logger.log("Payment canceled")
        case .failed(error: let error):
            logger.log("Payment error: \(error)")
        }
    }
}

Building

This project is a free Swift Package Manager module that uses the Skip plugin to transpile Swift into Kotlin.

Building the module requires that Skip be installed using Homebrew with brew install skiptools/skip/skip. This will also install the necessary build prerequisites: Kotlin, Gradle, and the Android build tools.

Testing

The module can be tested using the standard swift test command or by running the test target for the macOS destination in Xcode, which will run the Swift tests as well as the transpiled Kotlin JUnit tests in the Robolectric Android simulation environment.

Parity testing can be performed with skip test, which will output a table of the test results for both platforms.
