NWPusher

A macOS and iOS tool that lets developers send push notifications directly through Apple’s Push Notification Service without running a separate server. The application reads SSL certificates and private keys from the macOS keychain or from PKCS #12 files, constructs customizable payloads with syntax checking, and supports setting expiration, priority, and sandbox mode. It stores device tokens for reuse and reports detailed error messages returned by APNs, including feedback service data.

The accompanying framework can be integrated into other macOS or iOS projects via CocoaPods, Carthage, or direct source inclusion. It is modular, has no external dependencies, and provides documented APIs for programmatic push delivery, making it suitable for testing or automating notifications from custom tools.

Target users are developers who need to verify or debug APNs integration for iOS or macOS apps, especially during development when setting up a full push server is cumbersome. The tool’s error reporting and keychain handling simplify the workflow of obtaining certificates, managing device tokens, and sending test pushes.
