How to turn .scn from Documents folder into SCNNode programmatically?

I have a .scn file in a folder in the Documents folder in the iPhone. I've been trying to use SCNSceneSource to turn the .scn file as a SCNNode

//fileDestFolderURL is the folder that holds the .scn file
let sceneSource = SCNSceneSource(url: fileDestFolderURL, options: [:])
let scene = sceneSource?.scene(options: [:])
print(scene) //prints nil
print(scene?.rootNode) //prints nil

However, I keep getting nil :(

My ultimate goal is to take the SCNNode and add it to an ARSCNView.

If anyone could provide their input it would be greatly appreciated!

You should use SCNScene.init(url:options:) instead of SCNSceneSource (which is mostly meant for Collada files).

I'm using Objective-C to accomplish what you're asking. Here is some translated code that might help you. Here is an example with a Chair .scn model. I've noticed htat it is better to have the .scn file in the Models.scnassets folder 

class Chair {
    func loadModel() {
        let virtualObjectScene = SCNScene(named:"Models.scnassets/chair/chair.scn"")
        let wrapperNode = SCNNode()
        for child: SCNNode in virtualObjectScene?.rootNode?.childNodes {
            wrapperNode.addChildNode(child)
        }
        addChildNode(wrapperNode)
    }
}

What I do is instantiate an object of this Chair class and then call loadModel on this object. After that I can just add it as a child node to the scene's root node and it appears in the scene.
