iosのシミュレータ立ち上げの際に[Error: Could not find iPhone X simulator](ReactNative)

More than 1 year has passed since last update.

シミュレータ起動の際、エラー発生

ReactNativeでiosのシミュレータを立ち上げる際に下記エラーが発生しました。

Found Xcode project ReactNativePlatform.xcodeproj

Could not find iPhone X simulator

Error: Could not find iPhone X simulator

シミュレータが無いという文言が書いてあります。

解決法

/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.jsを開いて、下記記述を変更します。

if (!version.startsWith('iOS') && !version.startsWith('tvOS')) {
  continue;
}

if (!version.startsWith('com.apple.CoreSimulator.SimRuntime.iOS') && !version.startsWith('com.apple.CoreSimulator.SimRuntime.tvOS')) {
  continue;
}

参考

react-native run-ios returns Error: Could not find iPhone X simulator
