奇怪的terminal消息在Xcode 8

最近，我已经将我的Xcode版本更新到了8.当我启动并运行一个全新的项目时，在terminal中收到以下消息。

2016-09-07 15:28:43.759998 App[7932:128675] subsystem: com.apple.UIKit, category: HIDEventFiltered, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-07 15:28:43.762544 App[7932:128675] subsystem: com.apple.UIKit, category: HIDEventIncoming, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-07 15:28:43.790817 App[7932:128648] subsystem: com.apple.BaseBoard, category: MachPort, enable_level: 1, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 0, privacy_setting: 0, enable_private_data: 0 2016-09-07 15:28:43.827962 App[7932:128496] subsystem: com.apple.UIKit, category: StatusBar, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-07 15:28:43.998975 App[7932:128496] subsystem: com.apple.BackBoardServices.fence, category: App, enable_level: 1, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 0, privacy_setting: 0, enable_private_data: 0 

任何人都可以解释这是什么意思/他们为什么在这里？

PS：我从来没有用Xcode 7获得这些types的消息。

Answer 1

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

将OS_ACTIVITY_MODE添加为disable

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

试试这个：在你的环境variables上设置OS_ACTIVITY_MODE = disable
