目前，我正在尝试深入研究 PHPickerViewController 以从照片中同时选择多个图像。所以我想要用户选择的图像数组，我尝试了太多方法但没有运气。这是我的代码，请告诉我有最佳实践吗？

func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
        picker.dismiss(animated: true, completion: nil)
        var images: [UIImage?] = []
        var totalConversionsCompleted = 0
        for (index,result) in results.enumerated() {
            result.itemProvider.loadObject(ofClass: UIImage.self, completionHandler: { (object, error) in
                let image = object as? UIImage
                images.append(image)
                totalConversionsCompleted += 1
                if totalConversionsCompleted == index {
                    print("completion happen \(images)")
                }
            })
        }
    }
