IBDesignablesAgentCocoaTouch and Cocoa Touch Tool Builder interface eat my processor

Question

Does anyone know what these two are: IBDesignablesAgentCocoaTouchand Interface Builder Cocoa Touch Tooldo?

Every time I open Xcode, these two use so much CPU that my fans are at maximum speed.

I am using Xcode 9 beta 5 at the moment. Not sure if it all started with beta 5 or beta.

Can I do something to prevent them from using a large number of processors?

Answer 1

The problem seems to be fixed in Xcode 9 Beta 6
