title: Safe Area of Xcode 9
body: <p>While exploring <strong>Xcode9 Beta</strong> Found <strong>Safe Area</strong> on Interface builders View hierarchy viewer. Got curious and tried to know about Safe Area on Apples documentation, in gist the doc says <em>"The the view area which directly interacts with Auto layout"</em> But it did not satisfy me, I want to know Practical use of this new thing. </p>
  
  <p>Do any one have some clue? </p>

  <p><strong>Conclusion paragraph from Apple doc for Safe area.</strong></p>
  
  <blockquote>
    <p>The UILayoutGuide class is designed to perform all the tasks previously performed by dummy views, but to do it in a safer, more efficient manner. Layout guides do not define a new view. They do not participate in the view hierarchy. Instead, they simply define a rectangular region in their owning view’s coordinate system that can interact with Auto Layout.</p>
