A step by step guide on implementing and testing international product information for StoreKit In-App Purchases or Subscriptions.

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 a localized offering and developed a UI that allows an app to display products.

Please consult the guides below to learn how to setup StoreKit, create a StoreKit offering or design a UI that considers all StoreKit scenarios.

For guides on localizing In-App Purchases or Subscriptions, please consult the links below.

Step One: Implement the localized strings

When writing code for the product name and description, use the displayName and description StoreKit product properties.

If you are curious about what a Styleguide is, why we use it or how to implement one in Swift, please consult the articles below.

Step Two: Change the Default Localization

Change the StoreKit default localization in XCode to the language that you wish to test.

Step Three: Verify

Run the app and confirm that the product display names and descriptions appear as desired.
