Step 1: Open the file
/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js
Step 2: Change a line of code, from this:
if (!version.startsWith('iOS') && !version.startsWith('tvOS')) {
continue;
}
to this:
if (!version.startsWith('com.apple.CoreSimulator.SimRuntime.iOS') && !version.startsWith('com.apple.CoreSimulator.SimRuntime.tvOS')) {
continue;
}
Step 3:
after update to Xcode 11 xcrun returns true or false and not YES or NO as before.
goto
/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js
find
if (
simulator.availability !== '(available)' &&
simulator.isAvailable !== 'YES'
) {
continue;
}
and change it to
if (
simulator.availability !== '(available)' &&
simulator.isAvailable !== true
) {
continue;
}
react-native run-ios --simulator="iPhone 11"
