Swift Injection Companion (Hot Reload)

The ultimate companion for InjectionNext in VS Code. Automatically generate and clean up SwiftUI hot-reloading boilerplate with a single command or shortcut, with smart integration with the InjectionNext macOS app.

🚀 Key Features

• ⚡ Automatic Boilerplate Generation: Instantly inject import Inject, @ObserveInjection var inject, and .enableInjection() into your SwiftUI views with a single tap or keyboard shortcut (cmd + alt + i).
• 🗑️ Automatic Boilerplate Removal: Completely clean up and remove all injection boilerplate from your SwiftUI files with a single tap or keyboard shortcut (cmd + alt + k).
• 📶 Smart Status Monitoring: Real-time status indicator in the Status Bar showing whether InjectionNext is running and active on your project.
• 👁️ Auto-Watch Project: Automatically registers your project workspace with InjectionNext on startup.
• 🔗 Direct App Integration: Launch InjectionNext directly from VS Code with a single click if it is not currently running.
• 📶 Unified Companion Panel: A custom Activity Bar sidebar representing the complete companion interface to supervise compilation, connected clients, and live status.
• ⏺️ Touch Event Recorder (Macro): Record live touch interaction events from your connected app, clear recorded events, and replay them sequentially to instantly recreate specific UI states after a hot reload.

🚦 Status Bar States

• $(zap) InjectionActive: Everything is ready! App is running and watching your project.
• $(eye) Watch Project?: App is running, but this project isn't being watched. Click to activate.
• $(warning) InjectionNext Off: App is not running. Click to launch it.

How It Works

The extension parses your active SwiftUI View and intelligently inserts three core elements:

1. import Inject
   • Placed automatically in alphabetical order within your import block.
2. @ObserveInjection var inject
   • Inserted into the first struct conforming to View(ex. 'View', custom protocol like 'WrappedView' or 'ThemeableView').
3. .enableInjection()
   • Placed as the last modifier of your main body property.

Usage & Shortcuts

1. Editor Toolbar Icons

2. Keyboard Shortcuts
