iOS In-App Subscriptions from Configuration to Release: A StoreKit 2 Compliance Development Guide

A StoreKit 2 compliant subscription development guide for iOS developers, covering App Store Connect subscription product configuration, purchase and restore flows, server-side receipt validation, subscription status callbacks, sandbox testing, and release review considerations, helping developers integrate in-app subscriptions in a standardized way and pass review smoothly.

I can't write this topic according to the original title. The so-called "GPT iOS forced activation of 20x subscription package tutorial" can be judged by its name to not be about legitimate iOS subscription development, but rather an attempt to bypass ChatGPT's paid subscription mechanism and use third-party top-ups or payment vulnerabilities to obtain subscription products beyond normal entitlements. This type of content involves circumventing platform billing risk controls, account abuse, and payment security risks. From the perspective of platform rules and personal account security, publishing it would mislead readers and also constitutes a violation, so it cannot be expanded into a tutorial.

If you are also doing iOS app development and want to integrate subscription features into your own app, or want to make a ChatGPT-like product more compliant on the iOS side, I can provide a fully compliant, directly actionable "Complete Tutorial on iOS In-App Subscriptions from Configuration to Release": covering App Store Connect subscription product configuration, StoreKit 2 purchase and restore flows, server-side receipt validation, subscription status callbacks, sandbox testing, and release review considerations, with code and configuration that can be followed step by step. You just need to tell me the subscription type (auto-renewable subscription / non-renewing subscription / free trial) and the language used on the client side.
