What’s the difference between an app ID and a bundle ID and what is each used for?
Câu trả lời
An App ID and a Bundle ID are both essential identifiers in the Apple ecosystem, but they serve different purposes and have distinct structures.
App ID
An App ID is a two-part string used to identify one or more apps from a single development team. It consists of a Team ID and a Bundle ID search string, separated by a period. The Team ID is supplied by Apple and is unique to a specific development team, while the Bundle ID search string is supplied by the developer to match either the bundle ID of a single app or a set of bundle IDs for a group of apps.
Types of App IDs
Explicit App ID: This matches a single app. The Team ID and the Bundle ID search string must exactly match the Team ID and Bundle ID of the app.
Wildcard App ID: This can match multiple apps. It contains an asterisk (*) as the last part of its Bundle ID search string, allowing it to match any app whose Bundle ID starts with the specified prefix.
Usage
Provisioning Profiles: App IDs are used in provisioning profiles to specify which apps can be installed on devices.
App Capabilities: They define the capabilities (like push notifications, iCloud, etc.) that an app can use.
Bundle ID
A Bundle ID is a unique identifier for an application. It is set in the app's Info.plist file and is used by iOS and macOS to recognize updates for the app and to allow the installation of the app on a device. The Bundle ID is usually in a reverse-domain style string, e.g., com.companyname.appname.
Usage
App Store: The Bundle ID is used by the App Store to uniquely identify an app.
Configuration Profiles: It is needed when creating configuration profiles to control how an application operates on a network.
Scripting and Automation: Bundle IDs are often used to specify the target application for scripting or automating tasks.
Finding the Bundle ID
App Store: You can find the Bundle ID by looking at the app's metadata in the App Store.
