Just updated to Xcode 10.0 and recieved this error "missing argument for paramater 'backgroundColor'" when trying to create theme of whatsNewController.

 let myTheme =  WhatsNewViewController.Theme { (configuration) in
    configuration.backgroundColor = UIHelper.BARODARKCOLOR
    configuration.titleView.titleFont = .systemFont(ofSize: 30, weight: .semibold)
    configuration.titleView.titleColor = .white
    configuration.titleView.animation = .slideDown
    
    configuration.itemsView.titleFont = .systemFont(ofSize: 20, weight: .semibold)
    configuration.itemsView.titleColor = .white
    configuration.itemsView.subtitleFont = .systemFont(ofSize: 17)
    configuration.itemsView.subtitleColor = .white
    configuration.itemsView.animation = .slideUp
    
    configuration.completionButton.titleFont = .systemFont(ofSize: 17, weight: .semibold)
    configuration.completionButton.titleColor = .white
    configuration.completionButton.backgroundColor = UIHelper.BAROCOLOR
    configuration.completionButton.cornerRadius = 8
    
    
    }

Swift Version: 4.0
WhatsNewKit Version: 1.0.2
Any suggestions or workarounds? I tried updating WhatsNewKit to latest version but latest version seemed to be for swift version 4.2 and id like to get my project to build before the switch to 4.2.
