A lightweight library for writing HTTP web servers with Swift

Nuke is an image loading system designed to fetch, cache, and render images and short video clips within a user interface. It functions as an asset caching engine and a resumable download manager to handle the retrieval of remote media files. The framework includes a request priority manager to coordinate duplicate requests and order loading based on visual importance. It employs an image prefetching strategy to load visuals into memory before they are required and uses an LRU asset cache to reduce network traffic. The system covers broader capabilities in traffic management and data storage

Kingfisher is a library for downloading, caching, and displaying remote images in Swift applications. It provides an integrated framework that manages the entire lifecycle of remote assets, from initial network retrieval to final rendering within user interface components. The library distinguishes itself through a two-tiered storage mechanism that balances rapid access via volatile memory with persistent availability through disk caching. It features a modular processing pipeline that allows for dynamic image transformations, such as applying filters or geometric modifications, during the re

Perfect is a server-side Swift framework designed for building high-performance web applications, REST APIs, and backend services. It provides an asynchronous HTTP server that handles web traffic through an event loop, alongside a web template engine for generating dynamic HTML pages. The project includes a WebSocket communication library for implementing bidirectional, real-time data exchange between clients and servers. It also provides a database connector to establish connections and exchange data between Swift applications and external database stores. The framework's capabilities cover
