Swift UITextField Border bottom and shadow issues - ios

Question

I have a UITextField that must have a bottom border. Since autolayout use my code is this:
override func viewDidLayoutSubviews() {
let border = CALayer()
let width = CGFloat(0.5)
border.borderColor = UIColor.darkGray.withAlphaComponent(0.3).cgColor
border.frame = CGRect(x: 0, y: txtUsername.frame.size.height - width, width: txtUsername.frame.size.width, height: txtUsername.frame.size.height)
border.borderWidth = width
txtUsername.layer.addSublayer(border)
txtUsername.layer.masksToBounds = true
}
This, however, excludes the fact that when I touch the UITextField, this should create me a shadow. the code is this:
//ombra txtField
self.view.addSubview(txtUsername)
txtUsername.layer.shadowOffset = CGSize(width: 5, height: 10)
txtUsername.layer.shadowOpacity = 0.3
txtUsername.layer.shadowRadius = 10
txtUsername.layer.masksToBounds = false;
txtUsername.clipsToBounds = false
the one excludes the other. how do I fix?`

You can use CAShapeLayerShadow
func border(){
let border = CALayer()
let width = CGFloat(0.5)
border.borderColor = UIColor.darkGray.withAlphaComponent(1).cgColor
border.frame = CGRect(x: 0, y: CustomerTextBox.frame.size.height - width, width: CustomerTextBox.frame.size.width, height: CustomerTextBox.frame.size.height)
border.borderWidth = width
CustomerTextBox.layer.addSublayer(border)
CustomerTextBox.layer.masksToBounds = true
}
func shadow(){
let Shape = CAShapeLayer()
let myPath = UIBezierPath(ovalIn: CustomerTextBox.frame)
Shape.shadowPath = myPath.cgPath
Shape.shadowColor = UIColor.lightGray.cgColor
Shape.shadowOffset = CGSize(width: 5, height: 3)
Shape.shadowRadius = 5
Shape.shadowOpacity = 0.8
view.layer.insertSublayer(Shape, at: 0)
}
