In-App Purchases

In-app purchases are a great way to monetize your app and improve the user experience

TLDR

In order to create the best possible in-app purchase experiences for your users, it's important to keep up with the latest enhancements and updates to the iOS API.

Introduction to in-App Purchases

In-app purchases are a great way to monetize your app and improve the user experience by offering users the ability to buy digital or physical goods within your app. With the latest enhancements to StoreKit 2 and the App Store Server API, you can now create even better in-app purchase experiences on iOS. You can also sell products within your app using Google Play Billing.

The Latest Enhancements to in-App Purchases

These include the AppTransaction API for In-App Purchases and the StoreKit Message API. You can also now use SwiftUI APIs to create custom in-app purchase experiences.

In short, these enhancements make it easier than ever to create great in-app purchase experiences for your users. If you're not already using them, I highly recommend taking a look and seeing how they can be incorporated into your app.

How to Use the New APIs

If you want to use the new APIs, you'll need to complete a form in the Play Console that provides information about your app's privacy and security practices. Then, you can sell products within your app using Google Play. Starting on August 2, 2022, all new apps must use the Billing Library.

Using StoreKit Message Sheets

Starting with iOS 13, StoreKit message sheets are available for all in-app purchases. These message sheets provide a consistent look and feel for all in-app purchase dialogs, and can be customized with your own branding.

To use StoreKit message sheets, you first need to create a message sheet controller. This controller will manage the presentation of the message sheet and handle user interactions. Once you have created a controller, you can present the message sheet using the present(animated:completion:) method.

When the user taps on the purchase button, the StoreKit framework will display an animated loading indicator. This indicator will be displayed until the transaction is complete. Once the transaction is complete, the message sheet will be dismissed and your app will be notified via the SKPaymentTransactionObserver protocol.

Here are some best practices to keep in mind when implementing in-app purchases in your app:
