App IDs provide metadata and capabilities for an iOS application.
The app is uniquely identified in the app store via its Bundle ID
The App ID Prefix is pre-pended to the Bundle ID to allow the app to be searchable and should be set to the Team ID (allowing apps developed by the Team to be easily identified)
- Explicit App IDs: are used for a single app, and required when distributing to the App Store
- Wildcard App IDS: are used for a set of apps and cannot be distributed to the App Store
