David Harris developed Network Link Quality Monitoring for the DataDog/dd-sdk-ios repository, introducing a LinkQuality enum and integrating it into the network connection information. Using Swift and object-oriented programming principles, he ensured that the LinkQuality property returns a valid default when unavailable, addressing null behavior and improving the reliability of network telemetry data. His work included a focused fix for Objective-C bridging, enhancing stability and data quality for performance monitoring. The implementation was supported by unit testing to validate behavior. Over the course of the month, David delivered a single, well-scoped feature that deepened the SDK’s network insight capabilities without bug fixes.
