How to allow users to manage a Subscription in an app in Swift
A step by step guide on implementing and testing code that enables customers to upgrade, downgrade or cancel an Auto-Renewable Subscription in an App.
The guide was made using our Free iOS StoreKit 2 Open Source project which is recommended for developers or business folk wishing to learn about how In-App Purchases or Subscriptions work and the code behind them.
The following walkthrough assumes that you have already setup StoreKit with an offering, have developed a UI that allows an app to display and buy products and have already made at least one successful Auto-Renewable Subscription purchase.
Please consult the guides below to learn how to setup StoreKit, create a StoreKit offering, design a UI that considers all StoreKit scenarios or make StoreKit product purchases.
Step One: Implement the Utility
In XCode, create a new file and paste in the code below.
We recommend that you place it under Utils/StoreKit.
Step Two: Implement the code
In your app, wherever you wish to allow users to manage their subscriptions, add the code below.
Step Three: Verify
Run the app and test the functionality. It should pop up a modal similar to the one above.
The changes that you make should appear in the StoreKit Transaction manager.
