ImagePrefetcher - always returns failedResources!

[LegSho]

Hi,
ImagePrefetcher always returns every passed url as a failed, none is skipped or successfull. Implemented in a pure SwiftUI.

Here is the base code (implementation and calls) and logs (urls are valid):

Base code

- implementation

``
import Foundation
import Kingfisher

final class KingfisherImagePrefetcher {
static let shared = KingfisherImagePrefetcher()
var prefetchers: [Location: Kingfisher.ImagePrefetcher] = [:]

enum Location {
    case home, profile
}

}

extension KingfisherImagePrefetcher {
func startPrefetching(urls: [URL], for location: Location) {
prefetchers[location] = Kingfisher.ImagePrefetcher(urls: urls) {
skippedResources, failedResources, completedResources in
AppLog.network.error("These resources are prefetched: (completedResources)")
AppLog.network.error("These resources are skipped: (skippedResources)")
AppLog.network.error("These resources are failed: (failedResources)")
if !failedResources.isEmpty {
for resource in failedResources {
AppLog.network.error("Failed URL: (resource.downloadURL.absoluteString)")
}
}
}
prefetchers[location]?.start()
}

func stopPrefeching(_ location: Location) {
    prefetchers[location]?.stop()
}

}
``

- calls

`
func getProfiles() {
isLoading = true
let request = PaginationRequest(
page: 1,
perPage: 10
)
profileManager.getProfiles(page: request)
.receive(on: DispatchQueue.main)
.sink { [weak self] completion in
self?.isLoading = false

            switch completion {
            case .failure(let error):
                self?.error = .unexpectedError(error.localizedDescription)
            case .finished:
                self?.error = nil
            }
        } receiveValue: { [weak self] response in
            guard let self else { return }
            self.profiles = response?.currentItems ?? []
            
            if !profiles.isEmpty {
                if let currentItems = response?.currentItems {
                    if let urlStrings = response?.currentItems?.first.flatMap({ $0.getPhotos() }) {
                        let urls = urlStrings.compactMap { URL(string: $0) }
                        **KingfisherImagePrefetcher.shared.startPrefetching(urls: urls, for: .profile)**
                    }
                    self.currentProfile = currentItems.first
                }
            } else {
                self.currentProfile = nil
            }
        }
        .store(in: &cancellables)
}
