## What it is
A Go library for sending push notifications to iOS, macOS, tvOS, and Safari apps via Apple's APNs HTTP/2 provider API. It supports certificate and JWT token-based authentication, persistent connections, and modern iOS notification features.

## Use cases
- send push notifications to ios apps from go
- send apns notifications using jwt token authentication
- send voip pushkit notifications
- send safari push notifications
- send push notifications with http/2 apns protocol
- notify ios users from a go backend

## When to choose
- you need a fast, maintained Go client for Apple Push Notification service
- you want token-based (JWT) APNs authentication instead of certificates
- you need VoIP/PushKit or iOS 10+ notification features

## When to avoid
- you are not using Go
- you need push notifications for Android (use FCM instead)
- you need a hosted push service rather than a library

- function: http-client, sdk, auth
- domain: mobile-development, apple-ecosystem, apis, developer-tools
