## What it is
dsdump is a command-line tool that inspects Mach-O binaries, dumping symbol tables plus Objective-C classes and Swift type descriptors, acting as an improved nm and class-dump. It supports demangling, filtering, and multi-architecture binaries.

## Use cases
- dump objective-c classes from a mach-o binary
- inspect swift type descriptors in an ios app binary
- list symbols referenced by a macos executable
- reverse engineer an apple framework's classes
- demangle swift and c++ symbols from a binary

## When to choose
- you need to dump ObjC or Swift class info from Mach-O binaries on macOS
- you want an nm/class-dump replacement with filtering and demangling

## When to avoid
- you need accurate dumps of binaries using post-2021 dyld binding opcodes - the README recommends ipsw instead
- you need a maintained tool with a license or active bug fixes

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: reverse-engineering, parser, developer-tools
- domain: reverse-engineering, developer-tools, apple-ecosystem
- platform: cli
- tags: mach-o, class-dump, objective-c, swift, symbol-dump, binary-analysis, macos
