Axiom Storekit Ref

A comprehensive StoreKit 2 reference that covers the full API surface for Apple's in-app purchase framework. You get detailed documentation on all product types (consumables, non-consumables, subscriptions), transaction handling, and the async/await patterns that make modern IAP work less painful. Includes iOS 18.4 updates and WWDC 2025 code examples, which is helpful since Apple's official docs can be scattered. The 948 GitHub stars suggest it's actually being used in production. Worth having loaded if you're building or debugging purchase flows in SwiftUI apps, especially when you need to quickly reference the difference between product restoration rules or subscription states.
