How to pod Localized interface files(XIB, Storyboard) as xcode project structure and make internationalization work?

Question

As the changes of cocoapods 1.0.0.beta.1 say "Localized interface files (XIB, Storyboard) using Base Internationalization - Base.lproj/Main.xib and en.lproj/Main.strings are represented as a variant group named Main.xib" and as far as cocoapods 1.0.0.beta.1 "Special case interface files to use the XIB or Storyboard name for the variant group when using Base Internationalization."

I refer to the demo and use resource_bundles to organize my resources on my podspecs.

s.resource_bundles = {
     'Resources' => ['LocalizationDemo/LocalizationDemo/Resources/**/*.{lproj,storyboard}']
}

and my cocoapods version is 1.0.1 but the directories result is

-Resources
--en.lproj
---LocalizationDemo.strings
--LocalizationDemo.storyboard
--de.lproj
---LocalizationDemo.strings

It's not the result directories which I expected and the interface internationalization don't work. Cloud anyone show me a correct usage or demo？

ADD: I use import/export localization by xcode before be pod to other projects. and I want it's could work by imported xliff files directly instead of add the IBOutlet or a subclass for UI controls.

You should write classes for your controls used in XIB OR Storyboard Views & assign the classes to respective control types like this -

class LocalizedTextField: UITextField {

    override func drawPlaceholderInRect(rect: CGRect) {

        let localizedPlaceHolder = self.placeholder!.localized
        self.placeholder = localizedPlaceHolder
        super.drawPlaceholderInRect(rect)
    }
}
class LocalizedLabel : UILabel {
    override func awakeFromNib() {
        if let text = text {
            self.text = text.localized
            self.bounds.size.width = CGFloat.max
            self.sizeToFit()
        }
    }
}

class LocalizedButton : UIButton {
    override func awakeFromNib() {
        for state in [UIControlState.Normal, UIControlState.Highlighted, UIControlState.Selected, UIControlState.Disabled, UIControlState.Focused] {
            if let title = titleForState(state) {
                setTitle(title.localized, forState: state)
            }
        }
    }
}

extension String {

    var localized: String {
        let localizedValue =  NSLocalizedString(self, tableName: nil, bundle: NSBundle.mainBundle(), value: "", comment: "")
        if localizedValue == "" {

            return self
        }
        else
        {
            return localizedValue
        }
        return self

    }
}
