Xcode更新导致sb报错

Xcode更新至10.3.1运行项目报错:

Failed to find or create execution context for description ' System content for IBCocoaTouchFramework-ElevenAndLater scaleFactor=2x'. These intermediate objects were non-nil:

尝试clean,强退Xcode重新运行,无效,网上搜索到解决方案:

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

在终端运行这一命令,重新run,搞定!感谢 xiaoshitou 提供的解决方案
