ios – How do I save occasion of my customized object to fileManager in swift?

I’ve a category CustomContainer which I want to avoid wasting to fileManager. The Downside is that struct comprises AVPlayer & AVPlayerItem and I can not determine tips on how to deal with these. The construction of the code is in such a manner that I can not hold these AV gadgets out of the category. I’m able to cache them however can not seem to save them in fileManager.

class CustomContainer {
        
        var url: String
        var reset: Bool = false {
            didSet {
                if reset {
                    participant.pause()
                    participant.search(to: .zero)
                }
            }
        }
     var shouldPlayVideo: Bool {
        didSet {
            if playOn && playerItem.standing == .readyToPlay {
                participant.play()
            } else {
                participant.pause()
            }
        }
    }
        let participant: AVPlayer
        let playerItem: AVPlayerItem
        init(participant: AVPlayer, merchandise: AVPlayerItem, url: String) {
            self.participant = participant
            self.playerItem = merchandise
            self.url = url
        }
    }

Beneath is how I’m utilizing this CustomContainer class

func setupVideo(url: String) {
            guard let URL = URL(string: url) else {
                return
            }
            let asset = AVURLAsset(url: URL)
            let requestedKeys = ["playable"]
            asset.loadValuesAsynchronously(forKeys: requestedKeys) { [weak self] in
                guard let strongSelf = self else {
                    return
                }
                var error: NSError?
                let standing = asset.statusOfValue(forKey: "playable", error: &error)
                change standing {
                case .loaded:
                    break
                case .failed, .cancelled:
                    print("Didn't load asset efficiently")
                    return
                default:
                    print("Unkown state of asset")
                    return
                }
                let participant = AVPlayer()
                let merchandise = AVPlayerItem(asset: asset)
                DispatchQueue.fundamental.async {
                    let customContainer = CustomContainer(participant: participant, merchandise: merchandise, url: url)
                    //Saving in cache
                    strongSelf.videoCache.setObject(customContainer, forKey: url as NSString)
                    customContainer.participant.replaceCurrentItem(with: customContainer.playerItem)
                }
            }
        }

Utilizing the customContainer object that’s saved in cache later to play video

func playVideo(withLayer layer: AVPlayerLayer, url: String) {
            if let videoContainer = self.videoCache.object(forKey: url as NSString) {
                layer.participant = videoContainer.participant
                videoContainer.shouldPlayVideo = true
            }
        }
