#### 实际问题 ####

`react-native run-ios` 脚本却会抛出如下错误：

Could not find iPhone X simulator

在网上也能找到一些解决方案，比如下面这个：

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

上面文章的解决方案是将 `/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js` 中的

// Making sure the version of the simulator is an iOS or tvOS (Removes Apple Watch, etc)
    if (!version.startsWith('iOS') && !version.startsWith('tvOS')) {
        continue;
    }

改为

// 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;
    }

#### 解决方案 ####

不过这个得查看自己电脑装的 simulator 版本来确定，否则反而会改出问题

大家可以在上面代码前 `console.log(version)`，打印下自己的 simulator 版本

比如我打印出来的就是如下的列表

version >>>  iOS 12.1
    version >>>  watchOS 5.1
    version >>>  tvOS 12.1

所以我就需要将上面的代码改回至

// Making sure the version of the simulator is an iOS or tvOS (Removes Apple Watch, etc)
    if (!version.startsWith('iOS') && !version.startsWith('tvOS')) {
        continue;
    }
