make static function that brings UILabel

Hallo, i have main view conrtoller class, I would like to start the function in other UIview class.

When i make it "static func..." = there is an error - Instance member 'view' cannot be used on type 'BattleViewController'.

Thank You for help.

func setGameOverInfo() {

let gameOver = UILabel()

gameOver.text = "Game over\n" + "Your score: " + BattleViewController.updatedScore()

gameOver.numberOfLines = 2

gameOver.font = UIFont.systemFont(ofSize: 24)

gameOver.textColor = UIColor.white

gameOver.textAlignment = .center

view.addSubview(gameOver)

gameOver.translatesAutoresizingMaskIntoConstraints = false

let centerXGOConstraint = NSLayoutConstraint(item: gameOver, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)

let centerYGOConstraint = NSLayoutConstraint(item: gameOver, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: -20 * scale)

view.addConstraints([centerXGOConstraint, centerYGOConstraint])

}
