Xcode 9.0 simulators "disappeared"

Tags:

I recently installed Xcode 9.0 GM on my machine. I fired it up to play around and the only simulators I see in the scheme are iPhone 8, iPHone 8 Plus, and iPhone X. I clicked "Download Additional Simulators" thinking the solution would lie there.

I'm greeted with this screen, which is everything I previously had installed.

I dug around on the Apple Developer forum and found this post discussing a similar problem with a prior version of iOS. At the suggestion of one of the posters, I powered down my machine and booted it cold. I opened up Xcode 9.0 again and I have the same issue.

Any suggestions what I can get additional hardware to appear in my Xcode scheme? Thank you for reading.

In Xcode 10.3, I also lost all simulators but got them back by running

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

In case anyone else gets here and are in my situation, I just upgraded to Xcode 9.2 and the simulators were all missing, but quitting and relaunching Xcode restored them.
