React Native运行出现Could not find "iPhone X" simulator

打开项目文件夹下 'node_modules/react-native/local-cli/runios/findmatchingsimulator.js'
查找

if (!version.startswith('ios') && !version.startswith('tvos'))

修改为

if (!version.startswith('com.apple.coresimulator.simruntime.ios') && !version.startswith('com.apple.coresimulator.simruntime.tvos'))

查找

simulator.isavailable !== 'yes'

修改为

if (simulator.isavailable !== true)
