iOS: UIToolbar or UIView for keyboard in swift

Question

I am creating a UIView or a UIToolbar for my keyboard when I select a textfield. For example something like that in my viewDidLoad:

let customView = UIView(frame: CGRectMake(0, 0, self.view.frame.size.width, 40))
        customView.backgroundColor = UIColor(colorLiteralRed: 0.0, green: 0.0, blue: 0.0, alpha: 0.2)
        emailTextField.inputAccessoryView = customView

and ok it works fine. But to optimise this cose, which is the best solution? For example, put this code in an extension? Or in a separated Xib? To have a clean code and not fill my viewController with these stuff.

Any ideas?

Thanks

if you want all the UITextField have this :

let v = CustomView()
let textField = UITextField.appearance()
textField.inputAccessoryView = v

or make an extension then call it when you want :

extension UITextField{
    func addInputAccessoryView(){
        let v = CustomView()
        self.inputAccessoryView = v
    }
}
