• Go to the target App’s “Features” or “In-App Purchases” page.
• Click “+” to create new in-app purchase item, select “Auto-Renewable Subscription”.
• Fill in subscription name, product ID, price tier, description, and other detailed information.
• Upload subscription screenshots and descriptions for review.
• Save and submit for review.

3. Develop and Integrate Subscription Payment Features

• Integrate StoreKit framework in Xcode project.
• Use subscription Product ID to implement purchase, restore purchase, receipt validation, and other logic.
• Support sandbox test accounts for development testing.

Code Example (Pseudo-code):

iOS App Capabilities Options Detailed Guide

When configuring an App in the Apple Developer portal (Certificates, Identifiers & Profiles), developers can enable different “Capabilities” for their App. These capabilities are like installing different “plugins” for your App, granting it access to more system-level functions. Properly selecting and configuring Capabilities is fundamental to developing high-quality Apps.

What are Capabilities?

Capabilities are system-level function authorizations that Apple provides for Apps. Each capability corresponds to a specific type of hardware or service access permission. Only after enabling them can Apps legally and securely call related functions, such as push notifications, Apple Pay, health data access, etc.

iOS App In-App Subscription Payment: Complete StoreKit Development Process

StoreKit is Apple’s official framework for in-app purchases and subscription payments. The following is the complete development process for implementing in-app subscription payment using StoreKit, suitable for Swift projects.

1. Backend Preparation

• Create App entry in App Store Connect.
• Create new subscription item, configure product ID, pricing, description, etc., and submit for review.
• Wait for subscription item review approval.

2. Project Configuration

• In Xcode project, ensure In-App Purchase capability is enabled (Target → Signing & Capabilities → +Capability → In-App Purchase).
• Ensure Bundle ID matches App Store Connect.

3. Integrate StoreKit

3.1 Import StoreKit

import StoreKit

3.2 Get Product Information

let productIDs: Set<String> = ["com.demoapp.subscription.monthly"]
let request = SKProductsRequest(productIdentifiers: productIDs)
request.delegate = self
request.start()

Implement delegate methods:
