The simplest way to add cache to your AsyncImage
CachedAsyncImage ?️
CachedAsyncImage is AsyncImage, but with cache capabilities.
Usage
CachedAsyncImage has the exact same API and behavior as AsyncImage, so you just have to change this:
AsyncImage(url: logoURL)
to this:
CachedAsyncImage(url: logoURL)
In addition to AsyncImage initializers, you have the possibilities to specify the cash you want to use (by default URLCache.shared is used):
CachedAsyncImage(url: logoURL, urlCache: .imageCache)
// URLCache+imageCache.swift
extension URLCache {
static let imageCache = URLCache(memoryCapacity: 512*1000*1000, diskCapacity: 10*1000*1000*1000)
}
Remember when setting the cache the response (in this case our image) must be no larger than about 5% of the disk cache (See this discussion).
