Thanks for update! I tagged IBDecodable just now. Could you add test cases in IB for non-violated views to ensure that the linter won't report false positive result?

@kateinoigakukun Sure :) I just added test cases (fixture resource) for it.

• add non-violated table view cell, collection view cell and collection reusable view to storyboard and xib fixtures.
