How adjust project to track multiple objects?

How can I adjust this project to start tracking more than one object?

    }
    
    
    return node
}


func session(_ session: ARSession, didFailWithError error: Error) {
    // Present an error message to the user
    
}

func sessionWasInterrupted(_ session: ARSession) {
    // Inform the user that the session has been interrupted, for example, by presenting an overlay
    
}

func sessionInterruptionEnded(_ session: ARSession) {
    // Reset tracking and/or remove existing anchors if consistent tracking is required
    
}

}
`
I've tried to add multiple anchors but when I add it to the node it only loads the last one.

Unable to run the code

I'm unable to build the project available on github. Could you please help me
