When a closure parameter is optional, it becomes @escaping, so mark your animations parameter with @escaping:

typealias animationBlock = () -> Void

func fade(withAnimation animations: @escaping animationBlock) {
    UIView.transition(with: blankView!,
                      duration: TimeInterval(kAnimationDuration),
                      options: .transitionCrossDissolve,
                      animations: animations)
}
