## What it is
A command-line reverse engineering tool that restores stripped Objective-C symbol tables in iOS Mach-O binaries. It injects OC method and block symbols back into the binary so developers can set symbolic breakpoints with lldb.

## Use cases
- restore stripped symbols in an iOS app binary
- debug an iOS app with lldb using symbolic breakpoints
- inject Objective-C block symbols found via IDA into a mach-o file
- analyze a third-party iOS app's internal method calls
- re-sign and install a symbol-restored app bundle on an iPhone

## When to choose
- you need to reverse engineer or debug a stripped iOS app with lldb
- you want to restore Objective-C method and block symbols in a mach-o binary
- you already use IDA and want to enrich symbols for analysis

## When to avoid
- you need to restore symbols for non-Apple platforms or non-Objective-C binaries
- you want a maintained tool with an active release cycle or license
- you need a GUI-based reverse engineering workflow
