iOS SDK — Unified Checkout Sheet

One modal UI for Card, Bank (ACH), Apple Pay, and Google Pay (web). Uses encrypted checkout-session v3 when you pass a session.

SPM products: SwirepayCore, SwirepayCheckout
Import: import SwirepayCheckout

Step 1 — Choose enabled payment methods​

import SwirepayCore

let paymentTypes: Set<SwirepayCheckoutSessionPaymentType> = [
    .card,
    .achLegacy,
    .applePayUS,
]

Valid session paymentType values: CARD, ACH_LEGACY, APPLE_PAY_US.

Step 2 — Create checkout session​

let session = try await SwirepayAPIHelper.shared.createCheckoutSession(
    amountMinorUnits: 1000,        // .00 USD
    currencyCode: "USD",
    paymentTypes: paymentTypes
)

Step 3 — Present the sheet​

import SwirepayCheckout

let config = SwirepayCheckoutConfiguration(
    apiKey: apiKey,
    accountGid: accountGid,
    environment: .sandbox,
    currency: .usd,
    amountMinorUnits: 1000,
    merchantDisplayName: "Your Store",
    applePayMerchantIdentifier: "merchant.com.your.app",  // nil hides Apple Pay
    applePayCountryCode: "US",
    businessType: "BUSINESS",
    plaidIsTest: true,
    checkoutSession: session,
    walletCheckoutURL: URL(string: "https://your-hosted-checkout.example.com/"),  // Google Pay web
    prefill: SwirepayCheckoutPrefill(name: "Jane", email: "jane@example.com"),
    enabledPaymentTypes: paymentTypes
)

SwirepayCheckout.present(from: self, configuration: config) { result in
    switch result {
    case .success(let completion):
        print(completion.prettyJSONString)
        // completion.success, completion.paymentSessionGid, …
    case .failure(let error):
        print(error.localizedDescription)
    }
}

The sheet initializes the SDK internally when the user taps Pay or a wallet button.
