问题
Anyone else getting this since upgrading from Xcode 10.3 to Xcode 11 when running react-native run-ios and any idea to get back up and running?
CoreData: annotation: Failed to load optimized model at path '/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Frameworks/InstrumentsPackaging.framework/Versions/A/Resources/XRPackageModel.momd/XRPackageModel 9.0.omo'
error Could not find iPhone X simulator
回答1:
I remember this happening before and amending:
node_modules ▸ @react-native-community ▸ cli ▸ build ▸ commands ▸ runIOS ▸ findMatchingSimulator.js
As a current workaround, updating:
if (simulator.availability !== '(available)' && simulator.isAvailable !== 'YES') {
continue;
}
To:
if (simulator.availability !== '(available)' && simulator.isAvailable !== true) {
continue;
}
Seems to get me back up and running.
Hopefully this gets updated pronto.
"react-native": "^0.59.3"

You can change the default simulator to use.
react-native run-ios --simulator="iPhone 11 Pro Max"

Xcode 11 can't see iPhoneX or Other Simulator - First need to add new Simulator - Then click on the bottom left of the Simulator then choose device you wanna add 😎
回答4:
Open xcode and go to window > Device and Simulators... go to the Simulators tab and click the + in the bottom left, here you can add iphone X.
回答5:
The problem is that you are using a @react-native/cli version that doesn't detect XCode 11 simulators. You can either downgrade your XCode or install a @react-native/cli that supports it.
If you are not managing the version of @react-native/cli directly in your package.json you can simply remove your package-lock.json or yarn.lock file and install it again:
rm yarn.lock
yarn install
or
rm package-lock.json
npm install
