title: Set layout constraints in SpriteKit
body: <p>I have been searching all day, through forums, videos and web pages, if there is any way to set constraints when using <code>SpriteKit</code> in <code>GameScene.sks</code>.</p>
  
  <p>For example, if I wanted to set objects certain distances from the edge of the screen for EVERY device, what do I do? Is there anything similar to <code>UIKit</code>'s constraints?</p>
  
  <p>Here is my Pong game so far, just to learn Sprite Kit:

  <p>Can this be set in the Attributes Inspector some how, or is there any way to set this pragmatically?</p>
  
  <p>Thanks for any help on this, or any pointers in the right direction.</p>
