final class Key: NSObject {
override func isEqual(_ object: Any?) -> Bool {
guard let other = object as? Key else {
return false
}
return url == other.url
&& size == other.size
}

override var hash: Int {
return url.hashValue ^ Int(size.width) ^ Int(size.height)
}

let url: URL
let size: CGSize

init(url: URL, size: CGSize) {
self.url = url
self.size = size
}
}
