Transforms verbose Swift and Xcode build outputs into token-efficient TOON format for optimized AI analysis.
xcsift is a specialized command-line utility that bridges the gap between verbose Apple development logs and Large Language Models. By parsing standard xcodebuild and Swift Package Manager (SPM) output into a structured TOON format, it reduces token consumption by 30-60%. This allows coding agents to process build errors, warnings, and test results with significantly higher accuracy and lower latency, making it an essential tool for developers using AI to debug or maintain iOS, macOS, and Swift projects.
