what is nuke fr?

Nuke is a Swift library for loading and displaying images in Apple platform apps: iOS, macOS, tvOS, watchOS, and visionOS. When you build an app that shows images fetched from the internet, you need to handle downloading, caching, and displaying them efficiently. Nuke takes care of all of that so you do not have to write it yourself. The library stores images in two places: in memory for quick access while the app is running, and on disk so they load faster the next time the user opens the app. It can also prefetch images before the user scrolls to them, so the app feels more responsive. For images that support it, Nuke can show a low-quality preview while the full image is still downloading, which is called progressive loading. It supports common image formats including JPEG, WebP, GIF, and HEIF. Nuke ships as four separate modules you can mix and match. The core module handles the image loading pipeline. A UI module provides ready-made components for both SwiftUI and UIKit, including a LazyImage view that you drop into your SwiftUI layout with a single line of code. There is also an extensions module for UIKit's image views and a video module for short video clips. The README shows that the library compiles in under 2 seconds and has an automated test suite twice the size of the codebase itself. It has been in development since 2015. The current version requires Swift 6.2 and Xcode 26, targeting iOS 15 and equivalent releases on other Apple platforms. Older versions with lower requirements are also available. Installation is done through Swift Package Manager. Nuke is released under the MIT license.
