SpriteKit - Why SKNode's are not being touch detected
<p>I have reviewed countless references to try to understand why my scene is not behaving the way i expected it to, such as <a href="https://stackoverflow.com/questions/29320554/why-sknode-isnt-reacting-to-touch-in-spritekit-game">this</a>.</p>

<p>Here is my very simple SKScene (2 child nodes):</p>

<ul>
<li>The scene has a SpriteNode (which covers the entire scene as a background image). This has a zPosition = 0.</li>
<li>The scene has a 2nd node (SKNode) which itself has another child (up to 2 levels). This has a zPosiiton - 2.</li>
<li>ALL nodes have .userInteractionEnabled = false</li>
</ul>

<p>Issue:</p>

<p>When i click anywhere all i see is that the 1st child (SpriteNode) is touched. The 2nd child (SKNode) is never touch-detected.</p>

<p>Note that the z-ordering of the Nodes are being rendered as I expect them. It is the touch-detection that doesnt appear to be working.</p>

<p>Snippet of my touchesBegan method:</p>

<pre><code>       for touch in touches {
            let touchLocation = touch.locationInNode(self)
            let sceneTouchPoint = self.convertPointToView(touchLocation)
            let touchedNode = self.nodeAtPoint(sceneTouchPoint)
            if (touchedNode.name != nil) {
                print("Touched = \(touchedNode.name! as String)")
            }
        }
</code></pre>
