title: Changing Xcode View Positions programatically with Autolayout enabled
body: <p>I am working on an Xcode 6 / Swift Project and I have noticed that when I enable Auto layout I can no longer set positions of my Views programatically. As an example I tried to override my AutoLayout Constraints on a View in <code>ViewDidLoad</code> and it did not work.</p>
  
  <pre><code>override func viewDidLoad() { 
  super.viewDidLoad() 
  
  // This Does not work 
  self.myView.center = CGPointMake(150, 200)
  
  } 
  </code></pre>
  
  <p>How do I override Auto layout View Constraints Programatically?</p>
