Xcode 11 Upgrade | Could not find iPhone X simulator | XRPackageModel 9.0.omo

Question

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?

Core         


        

Answer 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.

You can change the default simulator to use.

react-native run-ios --simulator="iPhone 11 Pro Max"

Answer 3

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

Answer 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.

Answer 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
