Securely Manage iOS App Data With .xcconfig And CI/CD

Learn how to securely manage sensitive configuration data in iOS apps using `.xcconfig` files and environment variables. This approach improves security by keeping sensitive data out of version control and streamlines configuration for both local development and CI systems. Key steps include creating `.xcconfig` files for different environments, populating them with values from environment variables, and using shell scripts to update configuration files during the build process.
