Xcode 8中的奇怪终端消息

Question

最近,我将我的Xcode版本更新为8.当我启动并运行一个全新的项目时,我在终端中收到以下消息.

2016-09-07 15:28:43.759998 App[7932:128675] subsystem: com.apple.UIKit,

任何人都可以解释这些意思/他们为什么在这里？

PS:我从来没有使用Xcode 7获得这些类型的消息.

Answer 1

转到Product => Scheme => Edit Scheme或使用快捷键:CMD + <

添加OS_ACTIVITY_MODE为disable

我使用这个答案:从@iDevzilla中隐藏 -xcode -8-logs来解决这个问题:

试试这个:在你的环境变量上设置OS_ACTIVITY_MODE =禁用
