Strange terminal messages in Xcode 8

Question

I recently upgraded from Xcode to 8. When I start and run a completely new project, I get the following messages in my terminal.

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 

Can anyone explain what this means / why they are here?

PS: I never received these types of messages with Xcode 7.

Answer 1

Go to Product => Scheme => Edit Scheme or use the shortcut: CMD + <

Add OS_ACTIVITY_MODE as disable

And I use this answer: hide-xcode-8-logs from @iDevzilla to solve this problem:

Try the following: on your environment variables OS_ACTIVITY_MODE = disable
