set property at init with an extension in swift?

How can we use extension to set a default value ? For example, if I create an UILabel in my storyboard, i set text value to "toto" in the storyboard. Now I want to create an extension to set my text value to "popo" when the label will be init in the app. To be more clear, I want to do that to set a default value in the whole app to my UILabel. Hope this is clear. 

extension UILabel {
   open override func ??? { 
       self.text == "popo"
   }
}

Please, don't tell me to set ma value in the storyboard cause this not what i need.

Don't Create extension

You should create subclass of UILabel assign it to your needed place in storyboard 

import UIKit

class MyLabel: UILabel {


override func awakeFromNib() {
    super.awakeFromNib()

    self.text = "POPO"
}
}

You can use this class in storyboard this way

Can a "default" value for the text property be provided for labels created in a Storyboard? Yes.

Is it a good idea? Probably not...

Having said that, what you could do is override awakeFromNib (which is called after the view is loaded from a Storyboard/Nib file):

extension UILabel {

    open override func awakeFromNib() {
        super.awakeFromNib()
        self.text = "popo"
    }

}
