Mac iOS com.apple.CoreSimulator.SimDeviceType.undefined

命令行中编译项目成功，但是无法直接运行至模拟器，提示如下错误：

no target specified for emulator. deploying to undefined simulatordevice type "com.apple.coresimulator.simdevicetype.undefined" could not be found.[error] an error occurred while running cordova run ios (exit code 1).

解决方案：

在项目中运行如下命令

cd platforms/ios/cordova && npm install ios-sim@latest

原理还不清楚。
