StoreKit 2 in-app purchases are implemented using Product and Transaction APIs to load products, process purchases, verify transactions, and deliver entitlements. This provides secure subscription management and paywall integration across iOS 26+.

What is the best way to build paywalls using SubscriptionStoreView?▼
