I faced a similar issue and setting the merge policy solved the issue. managedObjectContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy

This code resolved it for me, but it will change the behavior of all AVPlayerViewControllers in the app. extension AVPlayerViewController { override open func viewDidLoad() { super.viewDidLoad() self.showsPlaybackControls = false } } If you want to only affect a particular instance, you may want to subclass AVPlayerViewController and use UIViewRepresentable to wrap it for SwiftUI.
