StoreKit 2 is a modern Swift-based API that allows developers to build type-safe in-app purchases and subscriptions. In this article, the author explains the process of setting up in-app purchases in a Swift project using StoreKit 2. The first step is to configure the project by adding in-app purchases in the project's 'Signing & Capabilities' tab. Then, a StoreKit configuration file can be created to test in-app purchases without a network connection. This file can be populated with test subscriptions and in-app purchases, or it can be synced with the App Store Connect to fetch the list of subscriptions and in-app purchases. The article also introduces the Store type, which handles the logic related to in-app purchases. The Product type, provided by StoreKit 2, encapsulates all the necessary information about an in-app purchase, such as the title, description, and price. The article concludes with information on how to handle the purchase result and validate the transaction using the VerificationResult type. Developers will find this article helpful in mastering StoreKit 2 and implementing type-safe in-app purchases in their Swift projects.
