Preload the scene? swift

Question

I am making a platform game and my scene has 400 different nodes, so when I go from the main menu to my scene

 self.removeAllChildren () if let nextScene = GameScene(fileNamed: "GameScene"){ let transition = SKTransition.doorway(withDuration: 3) view!.presentScene(nextScene, transition: transition) } 

I have a 3s freeze before my scene appears.

My question is: is there a way to preload the scene while I'm in the main menu to avoid this 3s freeze (which might increase if I add some nodes)
