title: safeAreaLayoutGuide - landscape mode
body: <p>I have set safeAreaLayoutGuide like this:</p>
  
  <pre><code>let guide = view.safeAreaLayoutGuide
  
  NSLayoutConstraint.activate([
    topControls.topAnchor.constraint(equalTo: guide.topAnchor, constant: 0)
  ])
  </code></pre>
  
  <p>this works great. However, when I rotate device to landscape mode, there is no status bar (battery, signal etc) and the offset from top of the screen is zero. That is correct, based on anchor. However, it does not look good. How can I add offset 20 for landscape during anchors creation? I don't want to change the constant based on orientation manually.</p>
