Crashdx

Diagnoses Apple .ips crash reports, symbolicating them against dSYMs and returning ranked, evidence-cited hypotheses about the likely cause.

What you can do

Crashdx parses Apple .ips crash reports, symbolicates them against dSYMs, and runs a deterministic rule-based engine that ranks competing hypotheses about the cause, each citing the specific facts that support it. It exposes the same pipeline over stdio as the crashdx_analyze and crashdx_symbolicate tools, returning a structured AnalysisReport. Verdicts are traceable to JSON paths in the original report, and the engine reports "inconclusive" when no hypothesis is clearly ahead.

When to use it

Useful when triaging Apple platform crashes and you want a ranked, checkable diagnosis rather than a raw symbolicated stack trace. Suited to macOS development workflows, CI parsing of crash reports, and agent-assisted crash triage where the reasoning should be auditable.

Requirements

macOS 14 or later, a Swift 6.2+ toolchain, and Xcode (not just Command Line Tools) for full symbolication via CrashSymbolicator.py; without Xcode it falls back to atos. Also needs /usr/bin/python3 and /usr/bin/dwarfdump. Runs locally over stdio; no accounts, API keys, or network access.
