InjectionIII
InjectionIII ist eine Suite von Entwicklungs-Utilities für Runtime-Code-Reloading, Ausdrucksauswertung und automatisierte Code-Injection. Es bietet ein System zum Neukompilieren modifizierter Quelldateien und zum Patchen von Funktionszeigern in einem laufenden Prozess, um das Anwendungsverhalten zu aktualisieren, ohne einen vollständigen Neustart zu erfordern.
Das Projekt nutzt Xcode-Build-Script-Extensions und einen Live-Code-Injector, um Swift- und Objective-C-Änderungen an Desktop-Anwendungen und physische Hardware zu übertragen. Es verfügt über einen Runtime-Evaluator, der String-basierte Swift-Ausdrücke ausführt, um den Status zu prüfen und Werte aus einer laufenden Anwendung abzurufen.
Die Funktionen umfassen Hot-Reloading für SwiftUI-Views, Storyboard-Szenen und Reducer-Logik sowie Tools für die Unit-Test-Iteration. Die Suite enthält zudem Diagnose-Utilities für Echtzeit-Anwendungs-Debugging und Method-Call-Tracing sowie Remote-Gerätesteuerung für Display-Mirroring und Touch-Input-Simulation.
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.
