FAQPage Schema

How do I implement StoreKit 2 in-app purchases for iOS apps?▼

StoreKit 2 in-app purchases are implemented using Product.products(for:) to load items, handling purchase flows with Transaction APIs, and starting a Transaction.updates listener at app launch to process transactions and verify entitlements.

What's the best way to handle auto-renewable subscriptions with StoreKit 2?▼

Auto-renewable subscriptions in StoreKit 2 are handled by loading subscription products, processing purchases through Transaction APIs, and tracking entitlement status via the Transaction.updates listener to manage renewal states and access rights.

How do I build a paywall using SubscriptionStoreView in SwiftUI?▼

A paywall is built in SwiftUI using SubscriptionStoreView or StoreView to display products, handling the purchase flow through StoreKit 2 Transaction APIs, and verifying entitlements to gate access after successful transactions.

Can I test StoreKit 2 in-app purchases locally without App Store Connect?▼

Local StoreKit 2 testing is supported using a StoreKit Configuration file and StoreKit testing tools, allowing you to simulate purchase flows, transaction updates, and entitlement checks for consumables, non-consumables, and subscriptions.

Do I need a Transaction.updates listener for StoreKit 2 entitlement management?▼

A Transaction.updates listener is required at app launch for StoreKit 2 entitlement management, as it processes transaction updates, verifies purchase validity, and ensures entitlements are synchronized when purchases or renewals occur.

What is the difference between StoreKit 2 and legacy StoreKit for handling purchases?▼

StoreKit 2 replaces legacy StoreKit APIs with a modern Swift-based approach using Product and Transaction types, eliminating delegates and simplifying product loading, purchase flows, restoration, and entitlement verification across consumables and subscriptions.
