creating custom UITextfield - swift

Question

how do i make custom UITextfield? i have created class with uitextfield as a subclass then i added label it shows up, but the border(UIView) are not showing up here is the code
import UIKit
class borderedTextField: UITextField{
let viewz:UIView! = UIView()
var border:UIView! = UIView()
var name:UILabel! = UILabel()
override func draw(_ rect: CGRect) {
self.addSubview(viewz)
}
override func layoutSubviews() {
backgroundColor = UIColor.green
}
func placement(){
border.frame.size.height = 15
border.backgroundColor = UIColor.black
border.translatesAutoresizingMaskIntoConstraints = false
viewz.addSubview(border)
border.heightAnchor.constraint(equalToConstant: 15).isActive = true
border.widthAnchor.constraint(equalToConstant: 100)
border.leftAnchor.constraint(equalTo: viewz.leftAnchor, constant: 10).isActive = true
border.bottomAnchor.constraint(equalTo: viewz.bottomAnchor, constant: -5).isActive = true
name.text = "whatt"
name.textAlignment = .left
name.textColor = UIColor.black
name.translatesAutoresizingMaskIntoConstraints = false
viewz.addSubview(name)
name.widthAnchor.constraint(equalToConstant: 100)
name.heightAnchor.constraint(equalToConstant: 50)
name.leftAnchor.constraint(equalTo: viewz.leftAnchor, constant: 5).isActive = true
name.topAnchor.constraint(equalTo: viewz.topAnchor, constant: 10).isActive = true
}
}
and i called it programatically (without storyboard) please let me know how to solve this problem without using storyboard i need it to be full code.
import UIKit
class signViewController: UIViewController,UITextFieldDelegate {
var animText:borderedTextField!
override func viewDidLoad() {
super.viewDidLoad()
let animText = borderedTextField()
animText.delegate = self
animText.placeholder = "click here"
animText.placement()
animText.frame = CGRect(x: 100, y: 500, width: 200, height: 90)
view.addSubview(animText)
}
}

Answer 1

You have to add init
override init (frame : CGRect) {
super.init(frame : frame)
self.placement()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.placement()
}
Also width of border is not active
border.widthAnchor.constraint(equalToConstant: 100).active = true
for name
name.widthAnchor.constraint(equalToConstant: 100).active = true
name.heightAnchor.constraint(equalToConstant: 50).active = true
Edit
border.leftAnchor.constraint(equalTo: self.leftAnchor, constant: 10).isActive = true
border.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: -5).isActive = true
