升级Xcode10.3报错System content for IBCocoaTouchFramework-EightAndLater

刚升级Xcode10.3 运行项目报错：

/Users/fcnc05/Desktop/app 名称/************/en.lproj/MainWindow.xib: Failed to find or create execution context for description ' System content for IBCocoaTouchFramework-EightAndLater scaleFactor=2x'. These intermediate objects were non-nil:(

解决方法：（终端）

Kill all simulator processes

$ sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

Set the correct Xcode path

$ sudo xcode-select -s  /Applications/Xcode.app/Contents/Developer

If that doesn’t work, reset all simulators

$ xcrun simctl erase all
