## What it does

The skill provides guidelines and patterns for handling `UserNotifications` and APNs in Swift 6.3 apps targeting iOS 26+, maintaining compatibility down to iOS 16. It covers registration via `UIApplicationDelegateAdaptor`, alert authorization, provisional delivery, and critical alerts. Related areas are decoupled explicitly: background workloads belong in `background-processing`, VoIP goes to `callkit`, and Live Activities are handled by `activitykit`.

When auditing notification code, the skill enforces key platform contracts. Device tokens must upload on every `didRegister` event rather than trusting a local cache. Because the iOS Simulator cannot register real device tokens with APNs, testing simulated pushes requires `.apns` files or `simctl push`.

Rich notifications also come with strict requirements. Service extensions need both an alert payload and `mutable-content: 1` to execute; silent pushes will not wake them. The skill flags missing fallbacks and ensures the completion handler runs exactly once, even if network attachments fail.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dpearson2699/swift-ios-skills --skill push-notifications -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/push-notifications/SKILL.md

## When to use it
- configure APNs token callbacks via `UIApplicationDelegateAdaptor`
- audit silent push payloads for `apns-push-type` and priority flags
- implement rich notification attachments in service extensions
- set up provisional or critical alert permissions using `UNUserNotificationCenter`

## Example prompts
- Help me implement APNs token registration in SwiftUI using AppDelegate
- Review my UNNotificationServiceExtension code for proper completion handler calls
- Configure a background push payload with apns-priority 5
