How do I test in-app purchases in Sandbox in Swift?

To test in-app purchases in sandbox mode using Swift, you need to follow several steps. First, ensure that you have set up your app's in-app purchases in App Store Connect. Then, you'll configure your app to recognize these purchases and test them in a sandbox environment. Here’s how to do it:

1. **Create a Sandbox Tester Account:** - Go to App Store Connect and create a sandbox user under Users and Access.

2. **Set Up Your App:** - Make sure your product identifiers are set up correctly in App Store Connect. - Integrate the StoreKit framework in your app.

3. **Implement In-App Purchase Logic:** - Use SKProductsRequest to retrieve product information.

4. **Test Your In-App Purchases:** - Log out of your current Apple ID on your device. - Log in with the sandbox tester account. - Test the purchase flow in your app by triggering a purchase.
