storekit

The storekit skill enables developers to implement, review, and enhance in-app purchases and subscription workflows using StoreKit 2. It solves the challenge of managing complex purchase flows, entitlements, and subscription states on iOS by providing modern, Swift-based APIs and best-practice guidance. By leveraging this skill, teams can streamline paywall implementations, transaction processing, and subscription management while ensuring compliance with App Store requirements and user experience standards.

Key features include support for various product types (consumable, non-consumable, auto-renewable, non-renewing), integration with SwiftUI paywalls via StoreView, ProductView, and SubscriptionStoreView, handling purchase flows with PurchaseAction or lower-level product.purchase(options:) calls, entitlement verification, and transaction monitoring using Transaction.updates. Additional capabilities cover offer codes, promotional and introductory offers, Family Sharing, Ask to Buy approvals, refund handling, billing retry logic, and StoreKit testing using configuration files. The skill also emphasizes best practices for restoring purchases and displaying Terms of Service or Privacy Policy links.

Storekit is ideal for iOS developers building apps with monetization strategies that include in-app purchases and subscriptions. It is particularly useful for teams looking to implement robust, maintainable paywalls, ensure accurate entitlement tracking across devices, and handle complex subscription scenarios. Target users include iOS app developers, technical leads performing code reviews of StoreKit integrations, and QA engineers validating purchase flows and entitlement states.
