## What it is
A lightweight Objective-C Cocoa library for detecting the running device's model, screen size, and OS version across iOS, iPadOS, watchOS, tvOS, and macOS. It provides simple enum-based checks for specific device models from iPhone 4 through iPhone 16 and Apple Silicon Macs.

## Use cases
- detect which iPhone model my app is running on
- check device screen size in iOS app
- determine if the device is an iPad Pro with M4
- get the human-readable device name like iPhone 16 Pro Max
- check if the screen is in zoom mode
- compare the running iOS version against a minimum
- detect Apple Watch series or Apple TV model
- identify Apple Silicon Mac model in a macOS app

## When to choose
- you need fine-grained device model or screen size detection on Apple platforms
- you want a tiny dependency with both Objective-C and Swift support
- you need coverage for the latest devices including iPhone 16 and M4 Macs

## When to avoid
- you only need generic device capability checks available via UIKit/UIDevice
- you target non-Apple platforms
- you need device detection for analytics rather than behavior branching

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, sdk
- domain: apple-ecosystem, mobile-development, developer-tools, cross-platform
- platform: cpp
- tags: device-detection, screen-size, objective-c, cocoapods, swift-package-manager, watchos, tvos, device-model, ios, macos, swift
