FAQPage Schema
How do I implement in-app purchases and subscriptions with StoreKit 2?▼

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?▼

SubscriptionStoreView builds paywalls by integrating StoreKit 2 product display, offer codes, introductory offers, and family sharing scenarios. It handles UI rendering while connecting to underlying Product and Transaction APIs for purchase flows.

How do I verify entitlements and restore previous purchases in StoreKit 2?▼

Entitlements verification and restore flows in StoreKit 2 use the Transaction API to validate purchase history and unlock features. The AppStore API syncs transaction data to ensure accurate entitlement delivery across devices.

Can I test StoreKit 2 subscriptions and promotional offers locally?▼

StoreKit 2 testing uses StoreKit configuration files to locally simulate subscriptions, promotional offers, win-back offers, and transaction processing. This allows end-to-end testing of paywall and purchase flows without App Store connectivity.

Does this StoreKit 2 approach support legacy in-app purchase APIs?▼

This StoreKit 2 approach ensures no legacy StoreKit usage, relying entirely on modern APIs like Product, Transaction, and AppStore. It delivers clear, tested patterns for iOS 26+ integration, testing, and App Store compliance.
