How to create view from its parent's nib using Swift - ios

Question

I thought this question is very simple but after long search without find an answer I'm trying to ask here:
I have a custom view (MyCustomView:UIView) with a .xib file.
To use this class with its nib I add a class function as following
class func addCustomViewToView(view: UIView)
{
let CV = NSBundle(forClass: MyCustomView.self).loadNibNamed("MyCustomView", owner: self, options: nil).first as! MyCustomView
CV.frame = CGRectMake(0, 0, view.frame.width, view.frame.height)
view.addSubview(CV)
}
In another place in my application I had to extend my custom view so I created a subClass of my custom view:
class MyExtendedCustomClass : MyCustomClass
{
...
}
I tried to override the class function, but I didn't find way to create a sub class item using parent's nib file.
What is the correct way to do this?
thanks

Despite a long time past from I asked the question, I'll add my solution hope it will help to someone.
The main issue was that while I called the function
addCustomViewToView(view: UIView)
in the subCustomView it created the view as the superCustomView class due to the line:
let CV = NSBundle...loadNibNamed(...).first as! MyCustomView
so...
Firstly, the way I init my CustomView:
var view:UIViwe!
override public init(frame: CGRect)
{
super.init(frame: frame)
self.commonInit()
}
required public init?(coder aDecoder: NSCoder)
{
super.init(coder: aDecoder)
self.commonInit()
}
private func commonInit()
{
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "CustomView", bundle: myBundle)
self.view = nib.instantiateWithOwner(self, options: nil).first as! UIView
self.view.frame = self.bounds
self.view.autoresizingMask = [.FlexibleHeight, .FlexibleWidth]
//here you can add things to your view....
self.addSubview(self.view)
}
override public class func layerClass() -> AnyClass
{
return AVPlayerLayer.self
}
Now I can initiate this class from the code using the
init(frame: CGRect)
and from storyboard by create view and define it's class to be my CustomView in that case the next init will be called:
init?(coder aDecoder: NSCoder)
After that, in the inherited View I shouldn't do nothing, it's "init" will call the "super.init" from the CustomView class and will init the nib file with no problems.
