100% CPU - Interface Builder for tvOS

Anyone else getting 100% CPU usage when using Interface Builder for tvOS projects on Xcode 15.0?

To reproduce, simply create a new project (Obj C or Swift), select "Storyboard interface" and add a blank UIViewController to the storyboard.

Note: Observed launchd_sim and PineBoard processes in Mac Activity Monitor app. Processes will stay at 98-100% until project is closed.

(No issue with iOS projects.)

Feedback report: FB13225766 (Xcode excessive CPU with interface builder (tvOS)). Includes sample project as per described above.

Minor update: Deleting "derived data" from ~/Library/Developer/Xcode changes behavior so that the processes causing high CPU use go away once closing Interface Builder or moving to view a text file. Returning to IB to view storyboards re-triggers high CPU use in all instances.
