## What it does

This skill guides implementation of the AccessorySetupKit system picker for Bluetooth and Wi-Fi accessory discovery and authorization, with communication handed over to CoreBluetooth or NetworkExtension. It covers `ASDiscoveryDescriptor`, proximity rules, and accessory capability options.

It explains how to create `ASAccessorySession`, wait for `.activated`, display `ASPickerDisplayItem`, and react to added, changed, or removed accessories. A Wi-Fi descriptor uses either `ssid` or `ssidPrefix`; setting both causes an app crash.

Configure `Info.plist`, including `NSAccessorySetupSupports`, before using the picker. Bluetooth values in those keys must match the descriptor, or discovery crashes the app. That is a reason to check UUIDs, names, and identifiers before testing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dpearson2699/swift-ios-skills --skill accessorysetupkit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/accessorysetupkit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/accessorysetupkit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dpearson2699/swift-ios-skills --skill accessorysetupkit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/accessorysetupkit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dpearson2699/swift-ios-skills --skill accessorysetupkit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/accessorysetupkit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dpearson2699/swift-ios-skills accessorysetupkit

## When to use it
- configure the system accessory picker
- define BLE discovery matching rules
- set up a Wi-Fi accessory by SSID
- handle `ASAccessorySession` events
- move from CoreBluetooth permission scanning

## Example prompts
- “Set up AccessorySetupKit discovery for a BLE accessory using its service UUID.”
- “Show how to create `ASAccessorySession` and wait for `.activated`.”
- “Check the `Info.plist` rules for a Wi-Fi accessory using `ssidPrefix`.”
