Could not load some videos

Hello there!

I am trying to use PHPickerViewController to load videos, but I got a problem: I could load some videos only not all.

I refer to the existing thread, but dosen't work.

This is the code I persent PHPickerViewController

Code Block swift
var config = PHPickerConfiguration()
config.selectionLimit = 1
config.filter = .videos
config.preferredAssetRepresentationMode = .current
let picker = PHPickerViewController(configuration: config)
picker.delegate = self
present(picker, animated: true, completion: nil)

Below is the relevant implementation of the method: func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]):

Code Block swift
picker.dismiss(animated: true, completion: nil)
for result in results {
  result.itemProvider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { (url, error) in
    if let error = error {
      print(error)
      return
    }
    guard let url = url else { return }
    let fileName = "\(Date().timeIntervalSince1970).\(url.pathExtension)"
    let newUrl = URL(fileURLWithPath: NSTemporaryDirectory() + fileName)
    try? FileManager.default.copyItem(at: url, to: newUrl)
    DispatchQueue.main.async {
      self.playVideo(newUrl)
    }
  }
}

Before I print error in line 5, Xcode printed 3 lines of error:

Code Block 
[AXRuntimeCommon] Unknown client: TestPHPicker
[default] [ERROR] Could not create a bookmark: NSError: Cocoa 257 "The file couldn’t be opened because you don’t have permission to view it." }
Error copying file type public.movie. Error: Error Domain=NSItemProviderErrorDomain Code=-1000 "Cannot load representation of type public.movie" UserInfo={NSLocalizedDescription=Cannot load representation of type public.movie, NSUnderlyingError=0x283a4a610 {Error Domain=NSCocoaErrorDomain Code=4101 "Couldn’t communicate with a helper application."

And I print error in line 5:

Code Block 
Error Domain=NSItemProviderErrorDomain Code=-1000 "Cannot load representation of type public.movie" UserInfo={NSLocalizedDescription=Cannot load representation of type public.movie, NSUnderlyingError=0x283a4a610 {Error Domain=NSCocoaErrorDomain Code=4101 "Couldn’t communicate with a helper application."

For some videos I can load successfully, and some videos I got error. I don't know why this happened.

I am testing this on an iPhone X iOS 14.0(18A373). Xcode 12.0 (12A7209).

Thanks for help!
