Axiom In App Purchases

charleswiltgen/axiom

This is a StoreKit 2 implementation guide for adding in-app purchases to iOS apps, targeting iOS 15+ with references to recent WWDC sessions through 2025. It's part of the larger Axiom skill collection and comes from a repo with nearly 1,000 stars, so there's community validation behind it. You'd reach for this when building purchase flows and want patterns that follow Apple's latest recommendations without digging through documentation yourself. The skill focuses on robust, testable implementations, which matters since IAP code tends to be finicky and hard to QA. Worth noting it assumes you're on recent tooling (Xcode 16 recommended), so if you're maintaining legacy projects this might push you toward newer APIs than you planned.
