## What it is
An ARC and GCD compatible Objective-C Reachability class for iOS and macOS, serving as a drop-in replacement for Apple's Reachability. It notifies apps of network interface changes via NSNotification or blocks, with configurable WWAN reachability.

## Use cases
- detect when the network becomes reachable or unreachable in an iOS app
- monitor network interface changes on macOS
- check whether a WWAN connection counts as reachable
- replace Apple's Reachability class with an ARC-compatible version
- get callbacks via blocks when connectivity status changes

## When to choose
- you need an Objective-C Reachability replacement for iOS or macOS
- you want block-based or notification-based network status callbacks
- you need ARC and GCD compatibility with legacy Apple Reachability semantics

## When to avoid
- you are on Swift-only modern projects that can use NWPathMonitor instead
- you need reachability inside a framework and cannot risk App Store rejection
- you target very old iOS versions without using the older tagged releases

## Facets
- artifact type: library
- maturity: stable
- function: networking, monitoring
- domain: mobile-development, networking, developer-tools
- platform: cpp
- tags: reachability, objective-c, gcd, arc, wwan, network-status, apple, ios, macos, swift
