AsyncImage

iOS >= 13 AsyncImage with the following characteristics:

• Loads the image when te view appears in the screen
• Cancel download request when it disappears
• (optional) in-memory cache to avoid too many URLRequest
• Thread safe
• Concurrency handling to avoid duplicate URLRequest
• Automatically reload when connectivity is regained
• Automatic retry when URLRequest fails

Getting started

You can clone this repository and run the AsyncImageDemo App.

AsyncImage("https://picsum.photos/200/300".urlRequest)
    .frame(width: 200, height: 200)

You can optionally use the configuration to apply modifiers to the Image rather than directly to the View returned by AsyncImage. If not specified, default ones applied are: resizable().renderingMode(.original)

Controlling the cache

Warning: Make sure to create an ImageCache and PublisherCache object somewhere in your app/module and injected to the AsyncImage object. Do not create a new one per each image, otherwise it will not work as intended.

let imageCache = PublisherCacheFactory.makeTemporaryCache()
let publisherCache = ImageCacheFactory.makeTemporaryCache()

AsyncImage(
    request: "https://picsum.photos/200/300".urlRequest,
    imageCache: imageCache,
    publisherCache: publisherCache
)
.frame(width: 200, height: 200)
