xcsift - Xcode Build Output Formatter

xcsift parses and formats xcodebuild/SPM output into token-efficient TOON format optimized for LLM consumption. It extracts compile errors, warnings, test failures, code coverage, and build timing from verbose Xcode output.

When to Use

Always pipe through xcsift when running:

• xcodebuild build / xcodebuild test
• swift build / swift test
• Any command that produces Xcode/SPM build output

Usage Pattern

Always redirect stderr and use TOON format:

# Build
xcodebuild build 2>&1 | xcsift -f toon
swift build 2>&1 | xcsift -f toon
