How do you load a .dae file into an SCNNode in iOS SceneKit?

Question

I am having trouble understanding how geometry from .dae files should be loaded into an iOS SceneKit scene graph.

I know that you can load .dae

Answer 1

The following answers didn't work for me.

Here is what worked for me in Xcode 7.0 beta 5 , iOS 9.0 beta / Swift 2.0:

3D model type: Collada 3D model name: "model.dae"

1. Load the scene:

   let lampScene = SCNScene(named: "art.scnassets/model.dae")
   

2. Access the child SCNode which is in the SCNScene:

   let lampRootNode = lampScene?.rootNode.childNodes[0]
   

3. Add the lamp node from the loaded scene into the current loaded and viewed scene:

   self.scene.rootNode.addChildNode(lampRootNode!)
   

NOTE: The self.scene exists due to:

private var scene:SCNScene!

Prior of adding the object to the scene I have made some scene setup according to the scene kit example. If you need the code mention it in the comments.

Hope it helps.
