The Hellgate iOS SDK is distributed via Cocoapods, Carthage and SPM.

Add the following line to your Podfile:

pod 'Hellgate-iOS-SDK'

1. Add the following line to your Cartfile:

github "starfish-codes/hgate2-ios-headless-sdk"

2. Run in same directory as your Cartfile:

$ carthage update --use-xcframeworks

3. Add the built XCFrameworks to your project under "Frameworks and Libraries"

Add the package via Xcode from https://github.com/starfish-codes/hgate2-ios-headless-sdk.git

import Hellgate-iOS-SDK

Use the following views to create a card form:

// Card number field, validation state and which side should the card images appear
CardNumberView(viewState: $viewModel.cardNumberViewState, image: .leading)
    .border()

// Expiry date field, validation state
ExpiryDateView(viewState: $viewModel.expiryViewState)
    .border()

// CVC and CVV view with view state and max length either .cvc or .cvv
CvcView(viewState: $viewModel.cvcViewState, length: .cvc)
    .border()

Each field has a ViewState which looks somewhat like this:

public enum ComponentState: String {
    case complete
    case incomplete
    case blank
    case invalid
}

public struct ViewState {
    public let state: ComponentState
}

The ViewStates can help to determine how the user is progressing in filling out the fields.

First we have to initialize a Hellgate session using the sessionId delivered from your backend.

let hellgate = await initHellgate(baseUrl: hellgateURL, sessionId: sessionId)

Next we need to get a card handler from the Hellgate session and then we can try and tokenize the card details based on the view states previously defined in the UI.

// First try to get a valid card handler
let cardHandlerResult = await hellgate.cardHandler()

if case let .success(handler) = cardHandlerResult {

    // Using the card handler and the previously defined view states
    // try and tokenize the card

    let tokenizeCardResult = await handler.tokenizeCard(
        cardNumberViewState,
        cvcViewState,
        expiryViewState,
        [:]
    )

    switch tokenizeCardResult {
    case let .success(data):
        // Results in a token id
        print(data.id)

    case let .failure(err):
        print(err.localizedDescription)
    }
}

If swiftlint is installed then it will run during the build process.
