It runs great on device (but I am currently not using the UIButton extension), I just cannot archive the project.

I also have issues archiving the app and assume it has something to do with NightNight. I'm on the swift3.0 branch... any updates on this?

[ArturGasparyan]

This is producing a warning (not an error), but it fails to archive:

NNMutableAttributedString.swift:81:31: warning: expression of type 'MixedColor?' is unused mixedAttrs[name]?.removeValue(forKey: range)
