iOS 11: Change size of UIBarButtonItem (image) in Swift 3

gistfile1.txt

func setUpMenuButton(){
    let menuBtn = UIButton(type: .custom)
    menuBtn.frame = CGRect(x: 0.0, y: 0.0, width: 20, height: 20)
    menuBtn.setImage(UIImage(named:"menuIcon"), for: .normal)
    menuBtn.addTarget(self, action: #selector(vc.onMenuButtonPressed(_:)), for: UIControlEvents.touchUpInside)

    let menuBarItem = UIBarButtonItem(customView: menuBtn)
    let currWidth = menuBarItem.customView?.widthAnchor.constraint(equalToConstant: 24)
    currWidth?.isActive = true
    let currHeight = menuBarItem.customView?.heightAnchor.constraint(equalToConstant: 24)
    currHeight?.isActive = true
    self.navigationItem.leftBarButtonItem = menuBarItem
}

Thank you so much! My UIBarButtonItem with a custom settings icon was too wide for some unexplained reason (the PDF icon was a square) and this was the only way to get it to the correct size.

Thanks man!
