SceneKit SCNNode init(mdlObject:) missing? : <p>I'm using Xcode 7.3.1, Swift 2.x, iOS target is 9.3. I can find convenience init <code>init(MDLObject mdlObject: MDLObject)</code> in <a href="https://developer.apple.com/library/ios/documentation/SceneKit/Reference/SCNNode_Class/#//apple_ref/occ/clm/SCNNode/nodeWithMDLObject:" rel="noreferrer" title="docs">Apple docs</a>, but I don't see it in my project. I opened standard game project starter, SceneKit is imported. I've tried:</p>

<ul>
<li>Double checking iOS version</li>
<li>Adding <code>import ModelIO</code></li>
<li>Finding "mdlObject:" in header files in SceneKit.framework - not found</li>
<li>Looking for alternative methods (maybe Apple moved it somewhere) but there are no other inits with that parameter, no class function, nor I found any corresponding export function in <code>MDLObject</code></li>
<li>Cleaning project...</li>
</ul>

<p>I can see all SceneKit classes, and I can create MDLAsset (part of ModelIO, can return MDLObjects) instance.
Any ideas, maybe I've overlooked something obvious?</p>
