Register an App ID
An App ID identifies your app in a provisioning profile. It is a two-part string used to identify one or more apps from a single development team. There are two types of App IDs: an explicit App ID, used for a single app, and a wildcard App ID, used for a set of apps. The app capabilities enabled for an App ID serve as an allow list of the capabilities one or more apps may use. You can enable app capabilities when you create an App ID or modify these settings later. In-App Purchase is enabled by default for an explicit App ID. Beginning with Xcode 11.4, a single App ID can be used to build iOS, macOS, tvOS, and watchOS apps.
Note: In order to configure the capabilities an app uses, you need to add them to a target in the Xcode project.
