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

frame lines, or legacy Apple

text format),

stop immediately

— this workflow does not apply. Report the format mismatch to the user and do not attempt any symbolication.

line 1 is a metadata header; the remaining lines are a separate JSON crash body. Parse them separately: Show more Installs 865 Repository dotnet/skills GitHub Stars 5.2K First Seen Apr 10, 2026 Security Audits Gen Agent Trust Hub Pass Socket Pass Snyk Pass
