Swift Compiler Error : Command /Applications/Xcode9.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 6

Question

I am working with a swift project in Xcode 9. It was working fine and suddenly got some error while running.

Command/Applications/Xcode9.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 6

I have tried many ways such as Cleaning the project, delete derived data from Xcode and restarting the Xcode .

But nothing helped for me.

Now Xcode is quiting automatically at regular occations. I have created another test project. That too showing same issue

我遇到同样的错误，但是我安装了Xcode 9.1，它比Xcode 9具有更好的性能和稳定性。
