概要
Objective-C obfuscator for Mach-O executables
履歴
iOS Class Guard is a command-line Objective-C obfuscator for Mach-O executables. Its README describes it as an extension of class-dump that renames Objective-C classes, protocols, properties, methods, and ivars by generating symbol maps used during compilation.
Polidea's repository was created for an iOS-specific obfuscation workflow built on top of the class-dump lineage. The README documents version 0.8, Homebrew installation, CocoaPods support, XIB and storyboard rewriting, JSON symbol maps, crash-report reversal, and dSYM symbol restoration workflows.
The repository notes that it is no longer maintained. That status matters historically because the tool belongs to an older Objective-C-heavy iOS security era, before Swift and newer Apple build-system conventions changed many app-hardening workflows.
The package has a narrower adoption profile than the other tools in this batch. Homebrew packages it from the 0.8 tag, while the upstream README itself recommends Homebrew as the simple installation path and a HEAD install for development snapshots.
The intended workflow is to run the tool against a compiled app, generate a symbols header and JSON map, include the generated header during compilation, and preserve the JSON map so crash reports and dSYMs can be translated back when needed. The README stresses that the result is not a complete security solution, only a way to make runtime inspection and code analysis harder.
For package catalogs, ios-class-guard is interesting because it packages a fragile intersection of reverse-engineering technique, Mach-O parsing, Xcode project mutation, CocoaPods integration, and mobile-app release process. It is not a general-purpose security layer; it is a snapshot of how Objective-C metadata exposure shaped iOS tooling.
