Autobooks SDK for iOS

The Autobooks SDK provides an interface for Apple's ProximityReader framework and various Autobooks web features and API to provide an integrated payment experience for your users. It presents its own standalone UI over that of the embedding app. As such, its architecture is most similar to that of a small app rather than a typical SDK.


The Autobooks SDK requires iOS 12 or above with the Tap to Pay feature requiring iOS 15.4 or later and a supported device (iPhone XS or later). To build it requires Xcode 13.4 or later.

Swift Package Manager

To integrate using Swift Package Manager, you can add the following line to your Package.swift dependencies array or add the URL directly to Xcode's package interface.

.package(url: "https://github.com/Autobooks/autobooks-ios.git", .upToNextMajor(from: "0.1.0"))


To integrate using CocoaPods, add the following to your Podfile.

pod 'Autobooks'

Once the SDK is added to your project, you can follow our integration guide and documentation to begin enabling the features in your app.


The Autobooks SDK has no dependencies but implements a much simplified version of the Swift Composable Architecture (TCA). It follows many of the same principles and has a few of the same types but is much more limited.


As in TCA, this SDK uses the term "domain" to group state, action, environment, and reducers. Currently the SDK has only a single domain, RootDomain, which contains the state and actions for all screens.


As in TCA, this SDK uses a Reducer type to process state mutations from actions while producing Effects. Unlike TCA, the SDK's Reducer is not built on top of Combine. Instead it simply runs Effects using Swift concurrency.


As in TCA, this SDK uses an Effect type as the return value from Actions processed by a Reducer. These Effects encapsulate an async bit of work, with a Sender type captured to send actions back into the Reducer if necessary.


As in TCA the Store type encapsulates the types within a domain, connecting actions to state mutations and allowing consumers to send actions while observing state. Unlike TCA, there is no ViewStore type, as the separation of Store and ViewStore is largely an optimization so far unnecessary in the SDK. As with TCA, the SDK's Store type uses Combine under the hood for observations, duplicate removal, and integration into SwiftUI's StateObject type.

User Interface

The Autobooks SDK is almost entirely written using SwiftUI. There are three exceptions. The SupportedFlowController is a UINavigationController subclass which replaces SwiftUI's unreliable native navigation with direct state observation driving stacks of UIHostingControllers containing the SwiftUI screens. And the UnsupportedViewController is a simple controller the screen shown when a device does not support the Tap to Pay feature, whether due to device limitations or OS version. This is implemented as a view controller due to the need to deploy it before iOS 13. And all web features are implemented in screens wrapping a WKWebView.

Release Notes

2 weeks ago

This release moves the SDK into the production environment by default but disables Tap to Pay and replaces it with the launch of the payment form web experience. A future release will enable the real Tap to Pay experience.
