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
    }
}

extension UITextField {
func cornerRadius(value: CGFloat) {
    self.layer.cornerRadius = value
    self.layer.borderWidth = 1.0
    self.layer.borderColor = UIColor.lightGray.cgColor
    self.layer.masksToBounds = true
}}

You should create a new class which is subclass of UITextField as this :

import UIKit

class YourTextField: UITextField {
    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)!
        self.setBorderColor()
    }
    required override init(frame: CGRect) {
        super.init(frame: frame)
        self.setBorderColor()
    }
    func setBorderColor(){
        self.layer.borderColor = .red // color you want
        self.layer.borderWidth = 3
        // code which is common for all text fields
    }
}

Now open xib select all text fields. In identity inspector, change the custom class to YourTextField This way even you have 1000 text fields in you project, no need to write even one more line for this purpose.
