Symbolicate .NET runtime frames in Apple platform .ips crash logs (iOS, tvOS, Mac Catalyst, macOS). Extracts UUIDs and addresses from the native backtrace, locates dSYM debug symbols, and runs atos to produce function names with source file and line numbers. Automatically downloads .dwarf symbols from the Microsoft symbol server using Mach-O UUIDs. USE FOR triaging a .NET MAUI or Mono app crash from an .ips file on any Apple platform, resolving native backtrace frames in libcoreclr or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Apple Platform Crash Log .NET Symbolication
Resolves native backtrace frames from .NET MAUI and Mono app crashes on Apple platforms (iOS, tvOS, Mac Catalyst, macOS) to function names, source files, and line numbers using Mach-O UUIDs and dSYM debug symbol bundles.
**Inputs:** Crash log file (`.ips` JSON format, iOS 15+ / macOS 12+), `atos` (from Xcode), optionally a connected iOS device to pull crash logs from.
**Do not use when:** The crashing library is not a .NET component (e.g., pure Swift/UIKit), or the crash log is an Android tombstone.
---
## Workflow
### Step 1: Parse the .ips Crash Log
**Format check:** Before proceeding, verify the file is `.ips` JSON format. The first line must be valid JSON. If the file is plain text (e.g., Android tombstone with `#NN pc` frame lines, or legacy Apple `.crash` text format), **stop immediately** — this workflow does not apply. Report the format mismatch to the user and do not attempt any symbolication.
The `.ips` file is **two-part JSON**: line 1 is a metadata header; the remaining lines are a separate JSON crash body. Parse them separately:
```python
lines = open('crash.ips').readlines()
…Read the whole file at its exact version.
How to install
mdr add dotnet/skills/apple-crash-symbolication@sha256:c8db1d3298cb94e3The line at the top of this page pins the label git:20260421.05aeb65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
