React Native version: 0.60.4

The Xcode is updated version 11 and the "iPhone X" simulator is disabled and cannot be run with an existing "react-native run-ios".
I have the same issue! Please fix!

But still, this is not building… You can also add Iphone X back by managing device in Xcode
Same issue, RN 0.59.10. The work around does not work.
Go to node_modules>@react-native-community>cli>build>commands>runIOS>findMatchingSimulator.js
Change the 'YES' in this line to true:
if (simulator.availability !== '(available)' && simulator.isAvailable !== true) {
continue;
This is how I got it working.
Thanks!
The iPhone X simulator has been replaced in Xcode 11 with the newer iPhone 11. It seems React is hard-coded to look for iPhone X. Seems odd to me there's no easy way to override this in the project config files.
You can specify the newer simulator using:
react-native run-ios --simulator "iPhone 11"
I found another way.
open Xcode > Add Additional Simulators > Create a new Simulator >
Device type > iPhone X > Create
Now you can run it without an "--simulator " option
@Resten1497 comment will work. For some reason, after the latest Xcode update, iPhone X was not present in the default list of simulators.
Adding an iPhoneX simulator is not working for me, on 0.59.8. I have 4 simulators for iPhone X, with 12.0, 12.1, 12.2 and 13.0 iOS versions and am still getting the same error message. Is there a specific version of iOS simulator that I need to re-install?
Editing the node_modules/react-native files is not an option for me as I'm working off of a git repository and need to fix this for others at my organization.
I found that iPhone X is not installed in Xcode 11.

You can build the app with this command as below
~$ react-native run-ios --simulator "iPhone 8"
