File 'NibView.swift' is part of module 'NibView'

It would appear this commit b33ac15 introduced an import which is irrelevant (for SPM at least). Xcode is throwing this exact warning:
> File 'NibView.swift' is part of module 'NibView'; ignoring import

I'm not sure if it's required for Carthage or Cocoapods, but on SPM it's generating a warning
