Build Status License: MIT contributions welcome

Declarative-style SwiftUI wrapper around asyncronous image views including smooth transitions and caching options.

Currently up to date with Xcode GM 2.


Asyncrounously download and display images declaratively. Supports placeholders and image transitions.

Flexible caching and image fetching done in background. Currently tested with basic List as seen in Example

As everyone gets to understand SwiftUI more, this project will evolve and get more features.

Fading Transition!


Enable or disable debug logging

SwURLDebug.loggingEnabled = true

Choose between global persistent or in-memory (default) caching

SwURL.setImageCache(type: .inMemory)
SwURL.setImageCache(type: .persistent)

... or provide your own caching implementation by using ImageCacheType

SwURL.setImageCache(type: .custom(ImageCacheType))


RemoteImageView is initialised with a URL, placeholder Image (default nil) and a .custom ImageTransitionType (default .none).

Upon initialisation, a resized image will be downloaded in the background and placeholder displayed as the image is loading, transitioning to the downloaded image when complete.

LandmarkRow is used in a List

struct LandmarkRow: View {
    var landmark: Landmark
    var body: some View {
        HStack {
            RemoteImageView(url: landmark.imageURL,
                            placeholderImage: Image.init("user"),
                            transition: .custom(transition: .opacity,
                                                animation: .easeOut(duration: 0.5)))
            Text(verbatim: landmark.name)
