WidgetKit Simulator is missing in first Sequoia beta?

I updated to Sequoia beta 1 and seem to have lost the macOS widgetkit simulator. is this expected?

My other mac running sonoma still has the simulator located at:

/System/Library/CoreServices/WidgetKit Simulator.app

trying to launch my widgets from Xcode 16 beta on my mac running sequoia results in this error:
