## What it is
Nuke is a Swift image loading and caching framework for Apple platforms, providing an ImagePipeline for fetching, processing, and displaying images with memory and disk caching. It includes NukeUI components like LazyImage for SwiftUI integration and supports progressive JPEG, WebP, GIF, and resumable downloads.

## Use cases
- load and display remote images in an iOS app
- cache images in memory and on disk
- show progressive JPEG images as they download
- decode and display WebP and GIF images
- prefetch images before they are needed
- decompress and resize images off the main thread

## When to choose
- building an iOS, macOS, watchOS, tvOS, or visionOS app that displays many remote images
- you need robust caching, request coalescing, and prefetching out of the box
- you want SwiftUI support with a simple LazyImage component
- performance and fast compile times matter

## When to avoid
- building for Android, web, or non-Apple platforms
- you need a general-purpose networking library rather than image loading
- your project does not use Swift or Swift Package Manager

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, caching, http-client, ui-components
- domain: mobile-development, image-processing, frontend
- platform: cross-platform
