Why does observer for status change of AVAsset not work?

Question

I implemented the following code from Apple. It is meant to observe for a change in the status of a playerItem. The problem is that for some reason it does not work. The observe function does not run when ready.

All relevant code is below:

func preloadVideo(media: Media) {
  //setup code, and then:
   media.playerItem1!.addObserver(self,
                                   forKeyPath: #keyPath(AVPlayerItem.status),
                                   options: [.old, .new],
                                   context: &playerItemContext)

}

Observe method:

private var playerItemContext = 0

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
    // Only handle observations for the playerItemContext
    print("jdslfhjkfdhaldfahjkflhajfldashkjfdshkjlas")
    guard context == &playerItemContext else {
        super.observeValue(forKeyPath: keyPath, of: object,change: change, context: context)
        return
    }
    
    if keyPath == #keyPath(AVPlayerItem.status) {
        let status: AVPlayerItem.Status
        
        // Get the status change from the change dictionary
        if let statusNumber = change?[.newKey] as? NSNumber {
            status = AVPlayerItem.Status(rawValue: statusNumber.intValue)!
        } else {
            status = .unknown
        }
        print("dsfdgddgdggdgdgdgddsafdsaf434fdfdg433444343")

        // Switch over the status
        switch status {
        case .readyToPlay:
            //Stop animation, and go to p3
            print("dsfdsafdsaf434433444343")

            if goToVideo {
                print("Runinfdsh sahkbdsfhbsadfbadsfl")
                goToP3()
            }
            
            break
        // Player item is ready to play.
        case .failed: break
        // Player item failed. See error.
        case .unknown: break
            // Player item is not yet ready.
        @unknown default: break
            //fatal error
        }
    }
}

This method will run first:

@objc func viewHandleTap(_ sender: UITapGestureRecognizer) {
    if selectedPost?.interimMedia.first?.imageURLString != nil || selectedPost?.interimMedia.first!.playerQueue?.status.rawValue == 1 {
        
        //do something
    } else {
        //status is 0 (video has not loaded yet)//load animation
        //this runs...
        goToVideo = true
    }
}

How can I make it work? Currently nothing in the observe method is printing.

If there is another method to accomplish this go ahead and post as answer.

Try by updating addObserver options to [.old, .new, .initial, .prior].
