description: "Understand the identity and configuration that travel with your app."

Project settings define how your app is named, identified, built, and connected to external services.

## App identity

The display name is what people see. The bundle identifier is the permanent technical identity Apple uses to connect builds, capabilities, and the App Store record. Choose it carefully before publishing.

## Secrets and environment values

Keep private credentials out of source code and chat. Use the secure project settings intended for environment values, and separate production credentials from development.
