xcodebuild raises libSwiftCore error

Im trying to build my application with xcode8 iOS 10 for simulator and i'm baffled by this error. It builds for release, just fine, however, it has a hard time building for simulator. I currently have both Objective-c and swift files in my source. Has anyone see this error before?

libswiftCore.dylib couldn't be copied

Here is the console log:

13:42:35 Copying /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/libswiftRemoteMirror.dylib to /Users/myUser/dir/artifacts/Debug-iphonesimulator/myApp.app/libswiftRemoteMirror.dylib

I get this same error when I've run low on disk space. Try moving the project to another drive, clean the project, and re-build.
