Where did the Homekit Accessory Simulator go in Xcode 6 beta 6?

In Xcode 6 Beta 5 and previous betas, I could open a HomeKit Accessory Simulator by right-clicking on the icon in the dock and choosing Open Developer Tool > HomeKit Accessory Simulator. In Xcode 6 beta 6, this seems to be no longer the case:

Recently (in 2016) Apple has moved the HomeKit Accessory Simulator to Additional Tools for XCode Package: https://developer.apple.com/download/more/?=additional%20tools

It looks like it was moved to the "Hardware IO Tools for Xcode" package, available from this page:

Hardware IO Tools for Xcode - Late August 2014

This package includes additional hardware i/o tools formerly bundled in the Xcode installer. These tools include: Apple Bluetooth Guidelines Validation, Bluetooth Explorer, HomeKit Accessory Simulator, IO Registry Explorer, Network Link Conditioner.prefpane, PacketLogger and Printer Simulator. These graphics tools support running on OS X 10.10 and OS X 10.9.
