Strange Terminal Messages in Xcode 8

Question

Recently, I have updated my Xcode version to 8. When I start and run an entirely new project, I get the following messages in my terminal.

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

Can anyone explain what these mean/why they are here?

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

Answer 1

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

Add OS_ACTIVITY_MODE as disable

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

Try this: On your Environment Variables set OS_ACTIVITY_MODE = disable
