How to add a SCNode to SceneKit from main art.scnassets folder - ios

Question

I want to add a .dae file that is sitting in my art.assets folder. to the scene. thats it lol and in swift preferable but I'll take Objective-C as well. Thanks here some code its just the basic scene kit file Xcode gives you.
Code:
import UIKit
import QuartzCore
import SceneKit
//============================================================
class GameViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//-------------------------
let scene = SCNScene(named: "art.scnassets/GenricFootball.dae")!
let scnView = self.view as! SCNView
scnView.scene = scene
scnView.allowsCameraControl = true
scnView.showsStatistics = false
scnView.backgroundColor = UIColor.whiteColor()
let tapGesture = UITapGestureRecognizer(target: self, action: "handleTap:")
scnView.addGestureRecognizer(tapGesture)
//--------------------------
let cameraNode = SCNNode()
cameraNode.camera = SCNCamera()
scene.rootNode.addChildNode(cameraNode)
cameraNode.position = SCNVector3(x: 0, y: 0, z: 15)
//-----------------------------------------------
let lightNode = SCNNode()
lightNode.light = SCNLight()
lightNode.light!.type = SCNLightTypeOmni
lightNode.position = SCNVector3(x: 0, y: 10, z: 10)
scene.rootNode.addChildNode(lightNode)
//-----------------------------------------------
let ambientLightNode = SCNNode()
ambientLightNode.light = SCNLight()
ambientLightNode.light!.type = SCNLightTypeAmbient
ambientLightNode.light!.color = UIColor.darkGrayColor()
scene.rootNode.addChildNode(ambientLightNode)
//----------------------------------------------
//_ = scene.rootNode.childNodeWithName("Bob", recursively: true)!
// _ = scene.rootNode.childNodeWithName("CampusField1", recursively: true)!
//--------------------------------------------------------
// Bob.runAction(SCNAction.repeatActionForever(SCNAction.rotateByX(0, y: 2, z: 0, duration: 1)))
}
func handleTap(gestureRecognize: UIGestureRecognizer) {
let scnView = self.view as! SCNView
let p = gestureRecognize.locationInView(scnView)
let hitResults = scnView.hitTest(p, options: nil)
if hitResults.count > 0 {
let result: AnyObject! = hitResults[0]
let material = result.node!.geometry!.firstMaterial!
SCNTransaction.begin()
SCNTransaction.setAnimationDuration(0.5)
SCNTransaction.setCompletionBlock {
SCNTransaction.begin()
SCNTransaction.setAnimationDuration(0.5)
material.emission.contents = UIColor.blackColor()
SCNTransaction.commit()
}
material.emission.contents = UIColor.yellowColor()
SCNTransaction.commit()
}
}
override func shouldAutorotate() -> Bool {
return true
}
override func prefersStatusBarHidden() -> Bool {
return true
}
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
return .AllButUpsideDown
} else {
return .All
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Release any cached data, images, etc that aren't in use.
}
}

I got to objects on the scene by using this code
Code:
let scene = SCNScene(named: "art.scnassets/GenricFootball.dae")!
let characterscene = SCNScene(named: "art.scnassets/untitled.dae")!
let monkey: SCNNode = characterscene.rootNode.childNodeWithName("Cube_001", recursively: true)!
scene.rootNode.addChildNode(monkey)
monkey.position = SCNVector3(x: 5, y: 0, z: 5)
