## プロジェクトの歴史と使われ方

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.

### プロジェクトの歴史

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The repository notes that it is no longer maintained.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.

### 採用の歴史

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.

### 使われ方

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.

### パッケージ好きにとっての重要性

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.

### タイムライン

- 2014: GitHub repository created for Polidea's iOS Class Guard project.
- 2015: Version 0.8 tag used by Homebrew as the stable source archive.
- After 2015: Repository README marked the project as no longer maintained.

### Related projects

- The upstream README names class-dump as the base project and links an ios-class-guard-example repository for demonstrating obfuscated and non-obfuscated app headers. The workflow also intersects with CocoaPods, Xcode precompiled headers, crash-reporting tools, and dSYM handling.
