Asyncrounously download and display images in Swift UI. Supports progress indicators, placeholders and image transitions.


Asyncrounously download and display images declaratively. Supports progress indicators, placeholders and image transitions. Flexible caching options.

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

This is an evolving project, if you have any ideas or feedback – feel free to create an issue or get in touch.

Fading Transition!

“But, AsyncImage

It’s great that Apple now has official support for async images, however:

Unlike AsyncImage, RemoteImageView

  • Is supported from iOS 13
  • Supports caching (in memory, on disk, and custom)
  • Supports progress indicators (including download fraction) and custom transitions
  • Has in depth, customisable logging


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 {
				url: landmark.imageURL,
				placeholderImage: Image.init("placeholder_avatar"),
				transition: .custom(transition: .opacity, animation: .easeOut(duration: 0.5))
			).imageProcessing({ image in
				return image
					.aspectRatio(contentMode: .fit)
			}).progress({ progress in    
    				return MyProgressBarView(progress: progress)
			Text(verbatim: landmark.name)

Available Parameters

Name Description Default
url URL of the remote source image. none
placeholderImage (optional)
Image to display whilst remote image data is being fetched and decoded.
transition (optional)
transition to occur when showing the loaded image.

Progress / Loading Indicators

Using function .progress . Display a loading indicator on top of the placeholder as the image loads. Once the image has finished downloading, the supplied loading indicator will hide Call progress on your RemoteImageView and return some View


).progress({ progress in    
    return MyProgressBarView(progress: progress)

Image Processing

Using function .imageProcessing . Process your placeholder and loaded images once they’ve been loaded. Apply resizing, aspect ratio, clipping and more! Call imageProcessing on your RemoteImageView and return some View


).imageProcessing({ image in    
    return image
        .aspectRatio(contentMode: .fit)

This gives you the power to return any View you want. RemoteImageView applies resizable() on all images by default.
