What is ObjectiveC.gcno? Should it be included in source code repository?

Question

I recently updated to Xcode 7. And just noticed this new file ObjectiveC.gcno in my project's root. My go-to source for gitignore files doesn't have it ignored. https://github.com/github/gitignore

It seems to be some sort of build artifact, but not sure. Should it be ignored?

My project has both Objective-C and Swift code together.

.GCNO files are files which are generated by Xcode in order to manage code coverage information.

You can read about it here in the Apple docs: Apple Documentation. There is no problem to either ignore them or push them to your repository.
