StoreKit
StoreKit is Apple's framework for integrating in-app purchases, subscriptions, and content delivery into iOS, macOS, watchOS, and tvOS applications. It provides APIs to handle transactions, manage subscriptions, and validate receipts, enabling developers to monetize their apps through the App Store. The framework supports various purchase types, including consumables, non-consumables, auto-renewable subscriptions, and non-renewing subscriptions.
Developers should learn StoreKit when building apps for Apple platforms that require monetization through in-app purchases or subscriptions, such as freemium games, productivity apps with premium features, or media streaming services. It is essential for compliance with App Store guidelines and ensures secure, reliable transaction handling, including features like family sharing, promotional offers, and subscription management for users.
