- Begin looking to the base and there you’ll discover the Sandbox Account area. Snap SignIn and give the analyzer account credentials.<\/span><\/li>\n<\/ul>\n
Note: <\/b>You don’t have to give your genuine Apple account credentials here.<\/span><\/p>\nWith Xcode 12 you can test In-App Purchases with simulator utilizing the accompanying advances :<\/i><\/b><\/p>\n\n- Make another configuration file.

- Consumable IAP<\/span><\/li>\n
- Non-Consumable IAP<\/span><\/li>\n<\/ul>\n
Note:<\/b> You need to create separate configuration files to test diverse IAP items and ensure that just each, in turn, is chosen while testing.<\/span><\/p>\n\n- Then, fill Reference Name, Product ID (same as this “com.organisation_name.project_name.iap_product_display_name” ) and Price. At that point go to the <\/span>Localizations<\/b> segment and enter <\/span>Display Name<\/b> and <\/span>Description<\/b> as we did in the <\/span>App Store Connect<\/b> record and press Cmd+S.
