Xcode Unable to boot device

2017 - 10 - 21

删除Simulator文件夹后报错:

Xcode Unable to boot device because it cannot be located on disk  

Use the device manager in Xcode or the simctl command line tool to either delete the device properly or erase contents and settings.

如下解:
打开Xcode -> Open Developer Tool -> iOS simulator

Hardware -> Device -> Manage Devices
删除旧Simulator 重新添加Simulator
