Summary

Added Swift SDK code example for ConverseStream API with Amazon Nova text model, including real-time stream processing implementation.

Security assessment

The change adds a programming example without any security-specific configurations, authentication mechanisms, or security best practices. It demonstrates standard API usage rather than addressing security concerns.
