AWS code-library documentation change

Service: code-library · 2025-08-16 · Documentation low

File: code-library/latest/ug/rds_example_rds_CreateDBInstance_section.md

Summary

Added Swift SDK code example for CreateDBInstance API with parameters including masterUsername/password

Security assessment

The change adds a standard code example for database creation without any specific security warnings, credential handling guidance, or vulnerability mitigation. While it includes password parameter documentation, this is part of normal API usage documentation rather than addressing a security issue.
