SwiftUI 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 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*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).
