How sdwebimage/sdwebimageswiftui works
SDWebImageSwiftUI is a SwiftUI image-loading framework built over SDWebImage. An app supplies a URL and view configuration to WebImage; its ImageManager loads and reports image state, which the view presents with placeholders, progress indicators, transitions, and optional animated playback. AnimatedImage provides a native-view path for animated content. The README also documents progressive loading, reusable downloads, request/response modification, transformers, and multiple caches/loaders, primarily as SDWebImage-backed capabilities. Wiring for unsampled view code is inferred only where documented; optional plugin integrations are shown separately.
