How to setup with other backends?

[konrad1977]

I havent successfully configured company-sourcekit to work with other backends. It will always swallow their result. If I set company-sourcekit at the end of my list it wont start.

Any example how to get this working with either :separate or :with https://company-mode.github.io/manual/Backends.html

I want to use company-keywords, company-debbrev-code company-tabnine and company-sourcekit.
