title: enumerateChildNodesWithName not working
body: <pre><code>-(void) checkCollisions {
      [self enumerateChildNodesWithName:@"minion" usingBlock: ^(SKNode *node, BOOL *stop){
          SKSpriteNode *minion = (SKSpriteNode *)node;
          if (CGRectIntersectsRect(minion.frame, CGRectMake(100, 100, 800, 900))) {

  <p>Hi Can anyone help with the above code it is not enumerating through my Sprites on screen. The checkCollision is definitely being called:</p>
  
  <pre><code>-(void)update:(CFTimeInterval)currentTime {
       [self checkCollisions];
  }
  </code></pre>
  
  <p>and I have added the SKSpriteNode, where it is created like so:</p>
  
  <pre><code> [self addChild:_minion];
  </code></pre>
