## What it does

This plugin delivers nine targeted skills for Swift and iOS workflows. It covers App Intents, App Shortcuts, and SwiftUI patterns, including iOS 26+ Liquid Glass APIs. It breaks large views into smaller components.

Simulator builds rely on a local `.mcp.json` config wired to XcodeBuildMCP. Through this bridge, Codex mirrors simulators in its browser, refreshes SwiftUI previews, and records symbolicated ETTrace profiles. Leak investigations compare `memgraph` snapshots.

Without XcodeBuildMCP active, simulator debugging cannot run. The `.codex-plugin/plugin.json` manifest connects the agent definitions and skill scripts across the plugin directory.

## When to use it
- capture symbolicated ETTrace profiles during simulator runs
- track down memory leaks by comparing memgraphs
- design App Intents and Shortcuts for system interactions
- refactor massive SwiftUI views into smaller subviews

## Example prompts
- Analyze memory leaks by comparing these two memgraph snapshots
- Refactor ProfileView.swift to break down this large view structure
- Record an ETTrace performance profile on the simulator for our checkout flow

# Build iOS Apps Plugin

This plugin packages iOS and Swift workflows in `plugins/build-ios-apps`.

It currently includes these skills:

- `ios-debugger-agent`
- `ios-simulator-browser`
- `ios-ettrace-performance`
- `ios-memgraph-leaks`
- `ios-app-intents`
- `swiftui-liquid-glass`
- `swiftui-performance-audit`
- `swiftui-ui-patterns`
- `swiftui-view-refactor`

## What It Covers

- designing App Intents, app entities, and App Shortcuts for system surfaces
- building and refactoring SwiftUI UI using current platform patterns
- reviewing or adopting iOS 26+ Liquid Glass APIs
- auditing SwiftUI performance and guiding profiling workflows
- capturing symbolicated ETTrace simulator profiles for focused app flows
- capturing and comparing iOS memgraphs to root-cause leaks
- debugging iOS apps on simulators with XcodeBuildMCP-backed flows
- mirroring Simulator in the browser and hot-reloading package-backed SwiftUI previews
- restructuring large SwiftUI views toward smaller, more stable compositions

## Plugin Structure

The plugin now lives at:

- `plugins/build-ios-apps/`

with this shape:

- `.codex-plugin/plugin.json`
  - required plugin manifest
  - defines plugin metadata and points Codex at the plugin contents

- `.mcp.json`
  - plugin-local MCP config
  - wires in XcodeBuildMCP for simulator build/run/debug workflows

- `agents/`
  - plugin-level agent metadata
  - currently includes `agents/openai.yaml` for the OpenAI surface

- `skills/`
  - the actual skill payload
  - each skill keeps the normal skill structure (`SKILL.md`, optional
    `agents/`, `references/`, `assets/`, `scripts/`)
```
