You can select Xcode > Open Developer Tool > Simulator and after simulator simulator loads, restart and then you will get whole list back.

Note : You can not work on both Xcode with all simulator same time. You have to close one Xcode with it's simulator then you can work on another.

Restart Xcode after simulator loading process is done. You will get whole list of Simulators.

Check your deployment target in the deployment info. 

This might have been changed if you are using latest version of Xcode where your deployment target will be automatically changed to higher versions of OS. 

Just switch to older version of OS which will display all the simulators required.

Running multiple versions of Xcode at the same time is only supported if all versions are Xcode 9+.

You can have older versions installed but only one running at a time.

If you try running multiple versions of Xcode that don't support it, the currently running one will loose access to simulator services until it is restarted (at which point the other one will loose access to its simulators).

Note that Console.app uses CoreSimulator.framework from the version of Xcode selected by xcode-select. If you launch Console, and xcode-select points to a different version of Xcode, it will cause the running Xcode to loose access to its sims.

Follow the below steps to fix this issue.

Step 2: Open Xcode 8 and go to Xcode Menu -> Open Developer tool -> Simulator.

Step 3: Quit the Xcode 8 and reopen.

after performing all troubleshooting that people suggest if it does not work for you, then go to preference and tap location tab and verify command line tool version is same as your xcode version , might your xcode command line tool version set to 9 or 9+ , set it back to 8. Hope so this will work for you.after that quit your xcode and open again
