## What it does

The skill covers Vision on iOS: text recognition, face and landmark detection, barcodes and QR codes, image segmentation, object tracking, document scanning. There is a Core ML section too, for running your own models through `CoreMLRequest` and `VNCoreMLRequest`.

Two API generations are documented. Modern Swift types such as `RecognizeTextRequest` and `DetectFaceRectanglesRequest` use `try await request.perform(on:)` and start at iOS 18. The legacy layer on `VNRequest` and `VNImageRequestHandler` stays relevant when your deployment target is lower. The skill suggests keeping legacy code in separate files or sections.

Vision coordinates are normalized with the origin at the bottom-left, so convert them to UIKit before drawing. For live camera scanning there is `DataScannerViewController` from VisionKit. Structured document reading with tables and lists arrived in iOS 26.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- pull text out of a photo with confidence scores
- find faces and landmarks in an image
- read a QR or barcode from a camera frame
- cut a person out of the background
- run a custom Core ML model through Vision

## Example prompts
- add Vision OCR to my scanning screen
- I need DataScannerViewController for live QR reading
- convert a face bounding box to UIKit coordinates
