Xcode

新建playground

Error running playground.

报错:Unable to find execution service for selected run destination


用Xcode新建playground界面直接报错

Unable to find execution service for selected run destination
  • 解决方法
    • 1.关闭Xcode
    • 2.在终端执行两行代码
      rm -rf ~/Library/Developer/CoreSimulator/Devices
      killall -9 com.apple.CoreSimulator.CoreSimulatorService
