Xcode Diagnostics

The Xcode Diagnostics MCP plugin extracts and parses build errors and warnings from Xcode's DerivedData logs, enabling AI assistants to quickly identify issues in Swift projects without manually searching through build logs. Developed by Mike R. Manzano, it provides tools to list available Xcode projects and extract structured diagnostic information including file paths, line numbers, error messages, and fix-it suggestions. The implementation features enhanced regex patterns optimized for capturing Swift concurrency-related warnings and includes comprehensive error categorization for syntax errors, type errors, protocol conformance issues, and Swift 6 language mode compatibility warnings, making it particularly valuable for developers working with Swift concurrency features.
