Sharing single class in all of ViewControllers and Views

Question

I have 4-5 screen. created using UIViewControllers and many UIViews inside these viewcontrollers. I have a single class Properties. Every UIViewController and UIView needs it.

Currently i am passing Properties into views and subviews and then back to parent views and so on. Is there any better option? Just initializing Properties at one place and every other class/view can use it change.
