SimAction is a macOS SwiftUI app that provides a unified control panel for:

• iOS Simulators (via xcrun simctl)
• Physical iOS Devices (via Xcode device services)

It aims to solve common developer pain points by providing specific actions like "Open URL", "Clipboard Control" (Simulators), and "Screenshot" in a native Mac app.

• Device Discovery: Lists all booted and shutdown simulators, plus connected physical devices.
• Filtering: View All, Simulators only, or Physical Devices only.
• Actions:
  • Open URL: Open deep links or websites on multiple devices simultaneously.
  • Clipboard: Read/Write clipboard for Simulators (Device ↔ Mac).
  • Screenshot: One-click screenshot saved to your disk.
• Persistence: Remembers up to 10 recent URLs and your last clipboard text.

• macOS 14.0+
• Xcode installed (Command Line Tools required for xcrun)

SimAction executes Apple developer tools such as xcrun simctl to interact with simulators. These tools cannot be executed from within a sandboxed macOS application. For SimAction to function correctly, the App Sandbox must be disabled.

1. Open the project in Xcode.
2. Select the SimAction.entitlements file in the project navigator.
3. Change the App Sandbox property to NO.

SimAction is a developer utility that relies on official Apple tooling to provide its core functionality. Requiring the App Sandbox to be disabled is a common and expected setup for developer tools that interact with system-level services or other developer utilities. The application does not require elevated privileges beyond the ability to execute these standard developer commands.

1. Open SimAction.xcodeproj in Xcode.
2. Select the SimAction scheme.
3. Build and Run (Cmd+R).
4. The app will ask for permission to control "System Events" or access disk if needed (though mostly it runs xcrun subprocesses).

• MVVM:
  • DeviceListViewModel: Central state manager.
  • SimctlClient: Wrapper for simctl commands.
  • DeviceDiscoveryClient: Wrapper for physical device discovery.
• SwiftUI: Pure SwiftUI views split into Sidebar, ActionPanel, and LogPanel.
