减少CoreData的调试输出? [英] Reduce debug output from CoreData?

问题描述

我正在使用CoreData的iOS/macOS项目中工作.它工作正常，但会向控制台输出大量调试信息.这使控制台无法使用，因为我的打印语句被埋在与CoreData相关的所有内容中.

I'm working on a iOS/macOS project where I'm using CoreData. It works fine, but it outputs enormous amounts of debugging info to the Console. This makes the Console unusable, since my print statements are buried in all the CoreData related stuff.

我有一个非常简单的CoreData设置，可以读取一些数据，所以这些不是错误，似乎只是一般的事件日志.我在使用CoreData的其他项目上也得到了相同的结果.

I have a pretty simple CoreData setup with fetching of some data, so these are not errors, just general event logs it seems. I have the same results on other projects I have used CoreData.

有什么方法可以减少或删除此日志到控制台?

一些示例数据(此处所有数据):

CoreData: warning: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _

performExportWithRequest:]_block_invoke_2(946): Finished export: <PFCloudKitExporter: 0x2838bd840>

推荐答案

尝试将它们添加为启动参数，看看是否有帮助

Try adding these as launch arguments see if it helps

-com.apple.CoreData.SQLDebug 0
-com.apple.CoreData.Logging.stderr 0               
-com.apple.CoreData.ConcurrencyDebug 0
-com.apple.CoreData.MigrationDebug 0

我在Apple文档中发现了这一点: 选择产品>方案>编辑方案".选择一个诸如运行"之类的操作，然后选择参数"选项卡.将带有调试级别值的com.apple.CoreData.CloudKitDebug用户默认设置作为应用程序的参数传递.

I found this in Apple docs: Choose Product > Scheme > Edit Scheme. Select an action such as Run, and select the Arguments tab. Pass the com.apple.CoreData.CloudKitDebug user default setting with a debug level value as an argument to the application.

 -com.apple.CoreData.CloudKitDebug 0

将最后一个添加为启动参数，您应该实现所需的功能.

Add this last one as a launch argument and you should achieve what you wanted.
