Declaration
func requestViewController(completionHandler: @escaping (UIViewfunc requestViewController(completionHandler: @escaping (NSViewDiscussion
The completion handler is called on a thread or dispatch queue internal to the audio unit's implementation. If the audio unit does not implement a custom view controller, it returns nil. If it has a custom view controller, it instantiates the view controller and returns it. The custom view controller must be a subclass of AUView.
