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. <img src="https://i.stack.imgur.com/170tT.png" alt="enter image description here"> I'm greeted with this screen, which is everything I previously had installed. <img src="https://i.stack.imgur.com/IxDvY.png" alt="enter image description here"> 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 <code>sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService</code>

Xcode 9.0 simulators "disappeared"

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.
