The device's data is no longer present at /Users/[user name]/Library/Developer/CoreSimulator/Devices/D651BCC7-29FD-4B91-82F6-E255E856EA2F/data.
I uninstalled xcode 9 and installed xcode 9.1, but when run project, following message was shown:
Unable to boot device because it cannot be located on disk. The device's data is no longer present at /Users/[user name]/Library/Developer/CoreSimulator/Devices/D651BCC7-29FD-4B91-82F6-E255E856EA2F/data.
I found "Developer" folder, but cannot find "CoreSimulator" folder.
I was able to resolve the issue running xcrun simctl erase all in Terminal.
Quit Xcode.app, Simulator.app, etc
Try the following commands in Terminal
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
rm -rf ~/Library/*/CoreSimulator
xcrun simctl erase all from above
xcrun simctl erase all and it started to work.
Go to Xcode menu Window-> Devices and Simulators -> Simulators tab, right-click the bad simulator and choose Delete from the menu list, then add it back from the left bottom entry again, it works!

Click on the simulators dropdown at the top of Xcode, and select Download Simulators....

From here, you can select which versions you want to download and for what devices.
Just run this command in terminal:
xcrun simctl shutdown all && xcrun simctl erase all
I had the same issue.
It worked for me by erasing the device which your Mac does not found.
