Transforms verbose Xcode and Swift build outputs into token-efficient structured data for AI coding agents.
xcsift is a specialized Swift command-line utility designed to bridge the gap between verbose Apple development logs and AI-driven development workflows. By transforming raw xcodebuild and Swift Package Manager (SPM) output into the structured TOON format, it reduces token consumption by 30-60%, allowing Claude and other agents to process build errors, warnings, and test results with significantly higher accuracy and lower cost. It is an essential tool for developers using AI to debug, test, and maintain iOS and macOS applications.
