Get the position of a sphere created in scn file

I created an scn file using Xcode (as you can see below), where there are two nodes (a sphere and a platform). I set up the position of the sphere:

I used a class which creates a node platform, which you can resize and move:

After pressing a button it places my scn file instead of that platform (with the same scale, position, and orientation) The problem is I don't know how to get sphere's position from the scene view.

  let sphere = SCNNode()
  self.scene.parent!.enumerateChildNodes { (node, _) in
        if node.name == "sphere" {
            sphere = node
            sphere.position = node.position
            print(sphere.position)
        }
    }

Using that code it always prints the position that I set up in the scn file (as you can see above), but I want the real position of it in the view.

With sphere.position you will get the position of sphere relative to its parent node. If you want the position in the scene you have to use sphere.worldPosition.
