title: Need a right and left buttons to move a sprite on the x axis
body: <p>I've searched and I can only find things about making it move by swipping/dragging. I'm a beginner making a game on <code>Xcode</code> with <code>Sprite-Kit</code>, and I'm doing pretty well so far, better than expected to be honest.  </p>
  
  <p>But I cant seem to figure out how to make a sprite move left and right when hitting left and right buttons.  I made the left <code>SKSpriteNode</code> and right <code>SKSpriteNode</code> (I don't think that's correct) and they show up where I want obviously, but I don't know how to enable them to be touched and make the sprite move.</p>
  
  <p>Sorry if this is a really amateur question, the answer will probably be obvious but I'm in a jam.</p>
