Possible to use application group container for caching?

[duc-ios]

I want to share the same ImageCache for my app and its extensions, is it possible?
FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.bundle.id")

Not quite sure but maybe it worths to try this before you setting an image:

guard let url = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.bundle.id") else {
    return
}
let myCache = ImageCache(name: "my_cache", cacheDirectoryURL: url)
KingfisherManager.shared.cache = myCache
