I would think that an instance of the Custom Class of the Scene being reference is initialised, but it's not. To do that, the only way I found was to do

    override func didMoveToView(view: SKView) {
        loadReferenceNode("ReferenceScene")
        referenceNode?.test()
    }
    
    func loadReferenceNode(name: String) {
        let referenceScene = SKScene(fileNamed: name)
        let childNode = childNodeWithName(name)
        referenceScene?.position = childNode!.position
        childNode?.removeFromParent()
        for child in referenceScene!.children {
            if let referenceChild = child as? ReferenceNode {
                referenceNode = referenceChild
            }
            child.removeFromParent()
            addChild(child)
        }
    }

Otherwise I have no clue how to call the "test()" method from within "GameScene".
