title: How to see the value of an object property in Xcode at a breakpoint
body: <p>I have a parent node contain all object :</p>
  
  <pre><code>SKNode* _moving;
  _moving = [SKNode node];
  [self addChild:_moving];
  ...
  [_moving addChild:spritenodetexture];
  </code></pre>
  
  <p>now I want to check the speed value of "_moving" which is "_moving.speed";
  So I set a break point at that line of condition: </p>
  
  <pre><code>if (_moving.speed &gt; 0) {
  </code></pre>
  
  <p>How do I know the value of  "_moving.speed" at that point ? Look into debug windows, I only see the address, postion, etc., but no value! Does Xcode Debug has tool to see it but I don't know ?
  (I am using SpriteKit in Xcode)</p>
