1，配置iPhone模拟器
"configurations": [
{
"name": "Debug iOS",
"cwd": "${workspaceFolder}",
"type": "reactnative",
"request": "launch",
"platform": "ios",
"target": "iPhone X"
}
2，react-native run ios出错，报找不到iPhone 模拟器
修改：
node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js中
// Making sure the version of the simulator is an iOS (Removes Apple Watch, etc)
if (version.indexOf('iOS') !== 0) {
continue;
}
修改成：
// Making sure the version of the simulator is an iOS or tvOS (Removes Apple Watch, etc)
if (!version.startsWith('com.apple.CoreSimulator.SimRuntime.iOS') && !version.startsWith('com.apple.CoreSimulator.SimRuntime.tvOS')) {
continue;
}
