Well, I guess those annoying PBItemCollectionServicer logs appear seconds after you copied (Command+ C) something into your iOS devices or iOS simulator which is running apps via Xcode.

The "universal clipboard" service (seems to) collects strings or images to share between your own iCloud devices (Mac, iOS devices ...)

It works in Sierra & iOS 10 environment Check this article

This log happens only when under simulator/iOS device while running on Xcode, I think.

I don't know why Xcode team let this somewhat should-be-hidden log displayed... for developers? But couldn't find any documentation... blah blah

"PBItemCollectionServicer connection disconnected." also logs when using iOS 11 table view drag-and-drop and completing a drop. It's benign there, from all I've observed.
