Answer 1

let border = CALayer()
     let lineWidth = CGFloat(0.3)
     border.borderColor = UIColor.lightGray.cgColor
     border.frame = CGRect(x: 0, y: emailTextField.frame.size.height - lineWidth, width:  emailTextField.frame.size.width, height: emailTextField.frame.size.height)
     border.borderWidth = lineWidth
     emailTextField.layer.addSublayer(border)
     emailTextField.layer.masksToBounds = true
