Storekit

Route StoreKit 2 in-app purchase implementation tasks to the correct Knowledge Contracts -- product loading, purchase initiation, transaction verification, entitlements, transaction updates, restoring purchases, and subscription status/renewal info. Use when calling Product.products(for:), product.purchase(), handling Product.PurchaseResult, checking VerificationResult, reading Transaction.currentEntitlements, calling transaction.finish(), listening to Transaction.updates, calling AppStore.sync(), or reading Product.SubscriptionInfo.Status/RenewalInfo/renewalState. v1 is StoreKit 2 async/await API only -- no legacy StoreKit 1 (SKPaymentQueue/SKProduct/SKPaymentTransaction), no server-side receipt validation or App Store Server API, no StoreKit Configuration file test setup. Triggers on StoreKit, Product.products, product.purchase, PurchaseResult, VerificationResult, currentEntitlements, transaction.finish, Transaction.updates, AppStore.sync, restore purchases, SubscriptionInfo.Status, RenewalInfo, renewalStat

StoreKit — Foundations Skill

Purpose

Route StoreKit 2 in-app purchase implementation tasks to the minimum required StoreKit Knowledge Contracts. v1 scope is the modern StoreKit 2 async/await API surface only — no legacy StoreKit 1, no server-side receipt validation or App Store Server API, no StoreKit Configuration file test setup in Xcode.

Routing

Load only the contracts relevant to the task. All paths relative to knowledge/storekit/.

Loading products with Product.products(for:), initiating a purchase with product.purchase(), or handling Product.PurchaseResult (.success/.userCancelled/.pending) -> product-loading-and-purchase.md
Checking a VerificationResult for .verified/.unverified, reading Transaction.currentEntitlements, or calling transaction.finish() -> transaction-verification-and-entitlements.md
The Transaction.updates listener task or calling AppStore.sync() to restore purchases -> transaction-updates-and-restoring-purchases.md
Reading Product.SubscriptionInfo.Status/RenewalInfo/renewalState, or same-subscription-group upgrade/downgrade behavior -> subscription-status-and-renewal-info.md

Never load more than the contracts relevant to the specific question.

Stop Conditions

Stop and report if the requested topic has no matching Knowledge Contract in knowledge/storekit/ — do not guess or fall back to general knowledge.

Legacy StoreKit 1 (SKPaymentQueue, SKProduct, SKPaymentTransaction) — Deferred
Server-side receipt validation and the App Store Server API — Deferred
StoreKit Configuration file test setup — Deferred
The App Review compliance angle — the requirement to use IAP to unlock content, prohibited alternative unlock mechanisms, loot-box odds disclosure, the restore-mechanism requirement, and the non-expiration rule for purchased currencies — owned by app-store-review-guidelines
