SwiftUI CachedAsyncImage 🗃️
April 21, 2024 · View on GitHub
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 cache you want to use (by default URLCache.shared is used), and to use URLRequest instead of URL:
CachedAsyncImage(urlRequest: logoURLRequest, urlCache: .imageCache)
// URLCache+imageCache.swift
extension URLCache {
static let imageCache = URLCache(memoryCapacity: 512_000_000, diskCapacity: 10_000_000_000)
}
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).
