How to change all TextField border colour in Swift 3

Question

How can I change all TextField border colour in Swift 3? I've built one iPad application with many TextFields in my .xib file and now I want to change border colour, but it seems like so many lines to write a particular textfield

Add this extension to create border for all textfields in your project.

extension UITextField
{
    open override func draw(_ rect: CGRect) {
        self.layer.cornerRadius = 3.0
        self.layer.borderWidth = 1.0
        self.layer.borderColor = UIColor.lightGray.cgColor
        self.layer.masksToBounds = true
    }
}
