How to get all the textfields from a view in swift

Question

I have a view which has more than 15 UITextFields. I have to set bottomBorder(extension) for all the UITextFields. I can set it one by one for all

Answer 1

extension:

extension UIView {
    func viewOfType(type:T.Type, process: (_ view:T) -> Void)
    {        
        if let view = self as? T
        {
            process(view)
        }
        else {
            for subView in subviews
            {
                subView.viewOfType(type:type, process:process)
            }
        }
    }
}

Usage:

view.viewOfType(type:UITextField.self) {
        view in

        view.text = "123"
}
