On some devices, loadFileRepresentation(forTypeIdentifier: completionHandler) take a loong time(about two minute) to callback result for some large video(about 200 MB, take by device camera).

environment:

Model: iPhone 12
Model Number: MGGM3CH/A
iOS Version: 18.3.2

PHPickerResult.NSItemProvider.loadFileRepresentation()

    // import PhotosUI
    func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
        picker.dismiss(animated: true, completion: nil)
        guard let provider = results.last?.itemProvider else { return }
        
        guard provider.hasItemConformingToTypeIdentifier(UTType.movie.identifier) else {
            return
        }
        
        Task {
            provider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { url, error in
                guard let url = url else {
                    return
                }
                
                // Do some stuff...
            }
        }
    }

ps: I also try some other function, eg: provide.loadItem(forTypeIdentifier:), but not work too.

Add the picker configuration:

        var configuration = PHPickerConfiguration(photoLibrary: PHPhotoLibrary.shared())
        configuration.filter = .any(of: [.images, .videos])
        configuration.selectionLimit = 1
        configuration.selection = .default
        configuration.preferredAssetRepresentationMode = .current
        configuration.disabledCapabilities = .search
        configuration.edgesWithoutContentMargins = .bottom
