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

I think you have deleted files and they're previously used – Mannopson Nov 22 '17 at 12:29 — Mannopson, Nov 22 '17 at 12:29
i never deleted anything @Mannopson – user6788419 Nov 22 '17 at 12:31 — user6788419, Nov 22 '17 at 12:31
It's a compiler error. Something went wrong from your side. – Mannopson Nov 22 '17 at 12:39 — Mannopson, Nov 22 '17 at 12:39
Can you identify what went wrong? @Mannopson – user6788419 Nov 22 '17 at 12:44 — user6788419, Nov 22 '17 at 12:44
