使用PHPickerViewController拍照时如何获取文件名

import PhotosUI

let picker = PHPickerViewController(configuration: PHPickerConfiguration())

class YourViewController: UIViewController, PHPickerViewControllerDelegate {
    // ...
    picker.delegate = self
    // ...
}

func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
    picker.dismiss(animated: true, completion: nil)
    
    guard let result = results.first else {
        return
    }
    
    result.itemProvider.loadFileRepresentation(forTypeIdentifier: UTType.image.identifier) { (url, error) in
        if let error = error {
            print("Error loading file: \(error.localizedDescription)")
            return
        }
        
        if let url = url {
            let fileName = url.lastPathComponent
            print("File name: \(fileName)")
        }
    }
}
