Xcode Log Filter

Filters verbose xcodebuild output to extract only actionable information. This skill helps reduce noise from massive build logs.

When to Use

  • •User pastes large xcodebuild output
  • •User complains about "too much output" or "noisy logs"
  • •Before analyzing build issues (pre-filter first)

Usage

Run the filter script on build output:

bash
swift ~/.claude/plugins/xcode-dx-skills/skills/xcode-log-filter/scripts/filter-log.swift [input-file]

Or pipe directly:

bash
cat build.log | swift ~/.claude/plugins/xcode-dx-skills/skills/xcode-log-filter/scripts/filter-log.swift

What Gets Filtered

Kept (actionable):

  • •Errors (compilation, linking, signing)
  • •Warnings
  • •Test failures
  • •Build phase start/end markers
  • •Summary lines

Removed (noise):

  • •Compilation progress for successful files
  • •Linking progress messages
  • •Copy file operations
  • •Code signing verbose output
  • •ProcessInfoPlistFile messages
  • •CreateBuildDirectory messages

Output Format

The script outputs JSON with:

  • •errors: Array of error messages with file/line info
  • •warnings: Array of warnings with file/line info
  • •summary: Build result summary
  • •filtered_line_count: How many lines were removed
