Why StoreKit 2 (not RevenueCat)?

Zero third-party SDK cost — no per-transaction fees or monthly pricing tiers.
First-party Apple library with JWS-signed transactions — cryptographic proof of purchase.
SubscriptionStoreView provides a native, App-Review-friendly paywall out of the box.
Full control over server-side verification via @apple/app-store-server-library.
For most indie apps shipping 1-3 subscription tiers, the built-in API covers everything RevenueCat offers, without the abstraction overhead.
