Xcsift

Use xcsift for all Swift and Xcode build commands. Pipe xcodebuild build, xcodebuild test, swift build, swift test through xcsift for structured TOON output with compile errors, warnings, test failures, code coverage, slow tests, and build timing. Essential for parsing Xcode build output, diagnosing compile errors, analyzing test results, and measuring code coverage in any Swift or Xcode project.

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

# Test
swift test 2>&1 | xcsift -f toon
xcodebuild test 2>&1 | xcsift -f toon

# With warnings
xcodebuild build 2>&1 | xcsift -f toon -w

# With code coverage
swift test --enable-code-coverage 2>&1 | xcsift -f toon -c
xcodebuild test -enableCodeCoverage YES 2>&1 | xcsift -f toon -c

# With detailed per-file coverage
swift test --enable-code-coverage 2>&1 | xcsift -f toon -c --coverage-details

# With executable targets
xcodebuild build 2>&1 | xcsift -f toon -e

# Strict CI mode (fail on warnings or errors)
xcodebuild build 2>&1 | xcsift -f toon -W -E

# Slow test detection
swift test 2>&1 | xcsift -f toon --slow-threshold 1.0

# Build info (per-target phases, timing, dependencies)
xcodebuild build 2>&1 | xcsift -f toon --build-info

Flag	Description
`-f toon`	TOON format (30-60% fewer tokens than JSON)
`-w`	Show detailed warnings list
`-W`	Treat warnings as errors (Werror)
`-q`	Quiet mode (no output on clean success)
`-c`	Include code coverage summary
`--coverage-details`	Per-file coverage breakdown (use with `-c`)
`-e`	Include executable targets
`-E`	Exit with non-zero code on build failure
`--build-info`	Per-target phases, timing, and dependencies
`--slow-threshold N`	Flag tests slower than N seconds
`--config PATH`	Use custom config file (default: `.xcsift.toml`)
`--init`	Generate `.xcsift.toml` template in current directory
