Ios PhotoKit:来自PHChangeRequestHelper中assetsd的响应无效

在我的应用程序中，我正在创建一个视频并将其保存到多媒体资料中。 有时（例如20次中有一次）代码无法保存视频

使用

AVAssetWriter

创建视频，并将其保存在应用程序临时目录中，直到客户端要求将其保存到库中：

- (void)saveVideoToGallery:(void(^)(NSError* error))completionHandler
{
    NSString* videoPath = [self tmpVideoFullPath];
    
    __block PHObjectPlaceholder *_placeholder = nil;
    
    [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
        
        PHAssetChangeRequest* createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:[NSURL fileURLWithPath:videoPath]];
        _placeholder = [createAssetRequest placeholderForCreatedAsset];
        
    } completionHandler:^(BOOL success, NSError * _Nullable error) {
        NSLog(@"TADAM Save video to album... %s", success? "✅":"❌");
        completionHandler(error);
    }];
}

saveVideoToGallery

在后台线程中调用

在我的应用程序中，还有一个模块在后台调用

PhotoKit

，但它只读取，不写入（fetchRequests）

PhotoKit

故障日志如下所示：

所以问题是：

如果PhotoKit出现问题，这可能是一个bug，还是我应该以某种方式分析我的代码

您是否知道在发生故障之前获取PhotoKit日志的一些环境变量
