title: Swift xcode auto layout even spacing between labels
body: <p>I have 3 labels which all have child label centered under them.</p>
  
  <p>I have a center label which is positioned in the center. Next to it I want to place two labels and give them both a even spacing between the center label and the screen edge. Like in css "margin-right/left: auto;"</p>
  
  <p>Is this possible to do with autolayout / constraints? I want them spacing to be even in 3 different screens.</p>
