How would I access subviews in CNContactViewController?

Question

How would I access the subviews in CNContactViewController. I know they are properties of the UIView instance in CNContactViewController, since CNContactViewController inherits from UIViewController.

Here is my code:

print("subviews count: \(self.contactViewController.view.subviews.count)")

Here is the result in debug window:

subviews count: 0
