PhotoKit：来自PHChangeRequestHelper中资产的无效响应

如何解决PhotoKit：来自PHChangeRequestHelper中资产的无效响应

在我的应用中，我正在创建视频并将其保存到图库中。有时（例如，每20次出现一次），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图库中为止：

- (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在后台线程中被调用。

在我的应用中，还有一个模块在后台调用PhotoKit，但它只读取而不是写入（fetchRequests）。

PhotoKit失败日志如下：

2020-09-10 13:22:02.315442+0300 MyApp[5448:1561813] [Gatekeeperxpc] Error getting remote object proxy for -[PLAssetsdPhotoKitClient requestUUIDWithCustomUUID:reply:]_block_invoke: Error Domain=com.apple.photos.error Code=41002 "Unable to obtain assetsd xpc proxy for getPhotoKitServiceWithReply:. assetsd Could have crashed" UserInfo={NSLocalizedDescription=Unable to obtain assetsd xpc proxy for getPhotoKitServiceWithReply:. assetsd Could have crashed,NSUnderlyingError=0x28399ef40 {Error Domain=NSCocoaErrorDomain Code=4097 "connection to service on pid 0 named com.apple.photos.service" UserInfo={NSDebugDescription=connection to service on pid 0 named com.apple.photos.service}}}

所以问题是：

如果使用PhotoKit可能是一个错误，还是应该以某种方式分析我的代码？
在发生故障之前，您是否知道一些环境变量来获取PhotoKit日志？
