You need to change your selector declaration to #selector(slide) and add an underscore before your method parameter func slide(_ sender: UISwipeGestureRecognizer):

class GameScene: SKScene {

    @objc func slide(_ sender: UISwipeGestureRecognizer){
        print("WORKS")
    }
    override func didMove(to view: SKView) {
        let upSwipe = UISwipeGestureRecognizer(target: self, action: #selector(slide))
        upSwipe.direction = .up
        view.addGestureRecognizer(upSwipe)
    }
}
