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)Install
