In the Application Platform you pick the Bundle Identifier for iOS and macOS from the identifiers on your App Store account. Create new identifiers in the Apple Developer portal.
Prerequisites
- Membership in the Apple Developer Program
- Access to Certificates, Identifiers & Profiles
- An App Store account stored in the platform
Create a Bundle Identifier
- Open developer.apple.com/account and go to Certificates, Identifiers & Profiles → Identifiers.
- Click +, choose App IDs, and continue.
- Select type App and enter a description.
- Enter the Bundle ID (reverse DNS, e.g.
com.example.app). Use separate identifiers for iOS and macOS when needed. - Enable the required capabilities and save.
After saving, the identifier appears in the platform dropdown once you select the matching App Store account (re-open the dialog or briefly switch the account if needed).
Tips
- Keep Bundle IDs stable per app (and platform) — changing them later is difficult.
- The API key needs permission to read identifiers and apps; otherwise the list stays empty.
