push-notifications

Implement, review, and debug local and remote notifications on iOS/macOS using UserNotifications and APNs. Covers permission flow, token registration, payload structure, foreground handling, notification actions, grouping, and rich notifications. Targets iOS 26+ with Swift 6.2, backward-compatible to iOS 16 unless noted.

Request notification authorization before doing anything else. The system prompt appears only once; subsequent calls return the stored decision.

Always check status before assuming permissions. The user can change settings at any time.

Implement, review, or debug push notifications in iOS/macOS apps — local notifications, remote (APNs) notifications, rich notifications, notification actions, silent pushes, and notification service/content extensions. Use when working with UNUserNotificationCenter, registering for remote notifications, handling notification payloads, setting up notification categories and actions, creating rich notification content, or debugging notification delivery. Trigger for any task involving alerts, badges, sounds, background pushes, or user notification permissions in Swift apps. Source: dpearson2699/swift-ios-skills.
