Xcode 9.0 simulators "disappeared"

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

My question was originally answered, but I found a more efficient way to do it with fastlane. Within fastlane, there's a tool called snapshot. The usage is as follows from terminal:

fastlane snapshot reset_simulators

Warning: This will delete all your simulators and replace by new ones! This is useful, if you run into weird problems when running snapshot.
