## What it does

The skill covers `Map` and `MapContentBuilder`, markers, annotations, polylines and polygons. For live position it points to `CLLocationUpdate.liveUpdates()`, for geofences to `CLMonitor`. There are sections on geocoding, search with autocomplete, and directions.

Two reference files sit inside: `references/mapkit-patterns.md` for map setup, search, routes, Look Around and snapshots, and `references/mapkit-corelocation-patterns.md` for the update lifecycle, background location, testing and privacy keys. The agent reads them when a task goes past the basic example.

The target is iOS 17 and later, with some sections marked iOS 18 and iOS 26. Tracking position requires `NSLocationWhenInUseUsageDescription` in Info.plist, otherwise the system blocks access. Worth checking before running the examples on a device.

### Claude Code (native platform)

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

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

### Cursor

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

2. **Manually: put the files in place**

```

### 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/mapkit/SKILL.md

## When to use it
- add a map with markers to a SwiftUI screen
- stream location updates through an async sequence
- set up a geofence and react to region entry
- convert an address to coordinates and back
- calculate a route and draw it as a polyline

## Example prompts
- Add a map to this screen with cafe markers and a user location button
- Track location with CLLocationUpdate.liveUpdates() and cancel the task when the view goes away
- Build place search with autocomplete and show results as markers
