swift - Deinit never called

Question

I'm creating a ViewController object an pushing it to a navigation controller. When the object is being popped from the stack - it is not being release and Deinit is not being called. What can be the reason for that?

Here's the code that pushes:

self.navigationController?.pushViewController(CustomViewController(), animated: true)

And here's the code that pops:

 self.navigationController?.popViewControllerAnimated(true)

I had similar problem. I added empty deinit method to my class and added breakpoint:

deinit {

}

As result it's never called.
As soon as I add some code to the body it started working as expected:

deinit {
    print("deinit called")
}

So be sure that your deinit method isn't empty.
PS. I am using Swift 2, Xcode 7.1
