Three flowers that represent StoreKit, Swift and XCode side by side. Beneath them sits the text “Restore Purchases.”

A step by step guide on implementing and testing code that enables customers to restore purchases for In-App Purchases or Subscriptions 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.

If you wish to learn more about how to setup StoreKit, create a StoreKit offering, create custom offer codes, design a UI that considers all StoreKit scenarios or make StoreKit product purchases.

Step One: Implement the Utility

Step Two: Implement the code

In your app, wherever you wish to allow users to restore purchases, add the code below.

Step Three: Verify
