title: Change a SF Symbol size inside a UIButton
body: <p>I am declaring a Button like this :</p>
  
  <pre><code>let menuButton = UIButton()
  </code></pre>
  
  <p>After that I am trying to change it's parameter and set his position on the view with the help of LBTATools (a pod) with this function:</p>
  
  <pre><code>fileprivate func setMenuButtonUI() {
          menuButton.setImage(UIImage(systemName: "line.horizontal.3.decrease.circle.fill"), for: .normal)
          view.addSubview(menuButton)
          menuButton.anchor(top: view.safeAreaLayoutGuide.topAnchor, leading: view.leadingAnchor, bottom: nil, trailing: nil, padding: .init(top: 20, left: 60, bottom: 0, right: 0), size: .init(width: 40, height: 40))
          menuButton.setupShadow(opacity: 1, radius: 5, offset: .zero, color: .darkGray)
          menuButton.tintColor = .red
      }
  </code></pre>
  
  <p>Everything is working well, I get the right color, position and even size.
  Only problem is it's size, I cannot change it with all the usual methods like <code>menuButton.imageView?.contentMode = .scaleAspectFit</code> etc..</p>
  
  <p>Probably it comes from the fact that it is a SF Symbol and not a normal image.</p>
  
  <p>The help of someone would be really appreciated.</p>
  
  <p>Thanks</p>
