Swift: create programmatically UIViewController from xib

Question

I'm approaching to swift in this days and I've a question.

What if I have to create programmatically a new UIViewController?

Easy with an empty/new view controller:

var controller: UIViewController = UIViewController()
controller.view.backgroundColor = UIColor.whiteColor()
self.presentViewController(controller, animated: true, completion: nil)

Now, I have a xib file that I would like to load on the controller:

var controller: UIViewController = UIViewController(nibName: "FeedDetail", bundle: nil)
controller.view.backgroundColor = UIColor.whiteColor()
self.presentViewController(controller, animated: true, completion: nil)

This crash because:

'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "FeedDetail" nib but the view outlet was not set.'

I've already read this post and I can't understand what's wrong!

if you are using Xib follow this

follo following steps

1) open your xib file then right click on files owner and drag to your first view

2) then bind that view with outlet of "view"
