dydump

A MobileSubstrate tweak for iOS that provides runtime class dumping capabilities with a user interface overlay.

Overview

dydump is an iOS tweak that integrates with the ClassDumpRuntime library to provide runtime class inspection and dumping functionality. The tweak presents a UI overlay that allows users to analyze and dump Objective-C classes from running applications.

Features

• Runtime class dumping using ClassDumpRuntime library
• User-friendly UI overlay for easy access
• Remote logging capabilities
• Automatic injection into target applications

Dependencies

• ClassDumpRuntime: A Swift library for runtime class dumping and reflection
• MobileSubstrate: iOS tweak injection framework
• Theos: Build system for iOS tweaks
