## What it does

This skill guides coding assistants through Apple's `WeatherService` APIs in Swift. It covers reading current observations and 25-hour forecast intervals. Temperatures arrive wrapped in `Measurement<UnitTemperature>`. Calling `.formatted()` ensures values match the user's locale.

The guide focuses on selective queries with `WeatherQuery` to avoid unnecessary network traffic. Custom date ranges support historical archives back to August 1, 2021. Single requests cap at 10 days. Calls fail without a paid Apple Developer Program account and the WeatherKit entitlement in Xcode.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

2. **Manually: put the files in place**
- File: `.github/skills/weatherkit/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/dpearson2699/swift-ios-skills --path skills/weatherkit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/weatherkit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dpearson2699/swift-ios-skills --skill weatherkit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dpearson2699/swift-ios-skills/tree/HEAD/skills/weatherkit/SKILL.md

## When to use it
- fetch current weather and 10-day forecasts using `WeatherService`
- configure selective `WeatherQuery` calls to reduce API payload sizes
- parse weather alerts and extract required detail attribution URLs
- retrieve past temperature records within supported date boundaries

## Example prompts
- Request current conditions and hourly forecasts via WeatherService in Swift
- How do I configure selective queries with WeatherQuery for tomorrow's weather?
- Show how to parse WeatherAlert objects and display their severity
