InjectionIII
InjectionIII 是一套开发工具，专为运行时代码重载、表达式求值和自动化代码注入而设计。它提供了一个系统，用于在活动进程中重新编译修改后的源文件并修补函数指针，从而在无需完全重启的情况下更新应用行为。
该项目利用 Xcode 构建脚本扩展和实时代码注入器，将 Swift 和 Objective-C 的更改交付到桌面应用和物理硬件。它具有一个运行时求值器，可执行基于字符串的 Swift 表达式，以检查状态并从正在运行的应用中检索值。
其功能涵盖 SwiftUI 视图、Storyboard 场景和 Reducer 逻辑的热重载，以及用于单元测试迭代的工具。该套件还包括用于实时应用调试和方法调用跟踪的诊断工具，以及用于显示镜像和触摸输入模拟的远程设备控制功能。
Features
- Hot Code Reloading - Recompiles modified source files and injects new implementations into a running process without requiring a full rebuild or restart.
- Live Code Injectors - Ships a live code injector that delivers Swift and Objective-C changes to running applications and physical devices without restarting.
- Runtime Expression Evaluation - Provides a mechanism to evaluate arbitrary Swift expressions at runtime to inspect and retrieve live application state.
- Desktop Hot Reloaders - Loads dynamic code changes into macOS desktop applications by bypassing sandbox and library validation restrictions.
- Build Script Extensions - Implements Xcode build script extensions that automate the streaming of dynamic code updates from desktop to target devices.
- iOS Binary Patching Tools - Provides a utility for bypassing sandbox restrictions and swizzling method implementations on physical iOS hardware.
- Library Injection - Implements library injection to load compiled code into running processes by bypassing system sandbox and library validation.
- Function Pointer Patching - Redirects application calls to new implementations by updating class tables and function pointers in memory.
- Method Swizzling - Swaps Objective-C method implementations at runtime to change application behavior without restarting the process.
- Swift Class Method Patching - Updates function pointers in class tables to redirect calls to newly injected implementations.
- Runtime Swift Evaluation - Executes specific Swift expressions as strings at runtime to retrieve typed results from a running application.
- Source File Watching - Monitors source files for modifications to trigger automatic recompilation and immediate injection into the target process.
- Physical Device Deployments - Injects code into physical devices and desktop applications by modifying build scripts and disabling runtime sandboxing.
- Static State Preservation - Maintains variable values across reloads by redirecting mutable accessors for static variables to the original bundle.
- Mach-O Symbol Rebinding - Updates value types and top-level functions using Mach-O symbol rebinding and dynamic linker redirection.
- Call Tracing - Logs every method call and argument across bundles and system libraries to trace execution flow.
- Symbol Interposing - Overrides global symbols and top-level functions using the dynamic linker to redirect execution to injected code.
- Redraw Triggers - Triggers SwiftUI view refreshes by observing state changes and resetting visual elements upon code injection.
- Runtime Execution Tracing - Provides real-time debugging by logging function calls and parameters during code injection to trace execution.
- Layout Reloaders - Refreshes storyboard scene layouts and triggers lifecycle events immediately after builds to preview interface changes.
- Hot-Reload State Preservation - Redirects mutable accessors for static variables so that injected code preserves existing values from the main bundle.
- Xcode and iOS Development Tools - Swift-based rewrite of the Xcode injection tool.
