SimBuild

What it does

• Auto-detects `.xcodeproj` or `.xcworkspace` in your workspace.
• Lets you pick an iOS simulator and an Xcode scheme.
• Builds a simulator target via `xcodebuild` and installs it on the chosen simulator.
• Launches the installed app and streams build logs in a dedicated output panel.

Requirements

• macOS with Xcode installed (includes iOS Simulator).
• Xcode command line tools available (`xcode-select -p` resolves).
• `xcrun simctl` available (bundled with Xcode).
• Node.js 18+ (for developing/building the extension).

Install

• VSIX: install the packaged VSIX directly in VS Code.
• Local build: clone the repo, run npm install then npm run compile.

Quickstart

1. Open the iOS project folder in VS Code that contains a `.xcodeproj` or `.xcworkspace`.
2. Open the Command Palette (Cmd/Ctrl+Shift+P) and choose:
   `SimBuild: Build`

   `SimBuild: Build and Run`
3. On first run, select a scheme and a simulator device.
4. Watch progress in the SimBuild output panel; it installs and launches the app when done.
