9.6.2 rc5/xcode 12.1 ipad simulator

[Mike Kerner]

I'm getting an error when trying to fire up the simulator:
"Booting available device failed with error:  Boot a device"
In case I was missing a simulator, I fired up XC and then made sure that
the ios simulator for 14.0 was installed, but no joy.

And God said, "This is good."
