“DTiPhoneSimulatorErrorDomain Code 2”

I don't understand your question. Please show the code. Of course you can call a func in an if: struct ContentView: View { let un = 1 let deux = 2 func one() -> some View { Text(One) } func two() -> some View { Text(Two) } var body: some View { if un > deux { one() } else { two() } } }

i changed my code now my code is this var background = SKSpriteNode() var background2 = SKSpriteNode() override func didMove(to view: SKView) { background = SKSpriteNode(imageNamed: New_Background) background.position = CGPoint(x: 0, y:0) background.zPosition = -2 / background.size = CGSize(width:self.frame.size.width*2,height:self.frame.size.height*2) background2 = SKSpriteNode(imageNamed: New_Background) background2.position = CGPoint(x: 0, y:0) / background2.zPosition = -2 background2.size = CGSize(width:self.frame.size.width*2,height:self.frame.size.height*2) self.addChild(background) self.addChild(background2) self.addChild(background3) vitesse = SKAction.repeatForever(SKAction.move(by: CGVector(dx: -self.frame.size.width, dy: 0), duration: 2)) background.run(vitesse) background2.run(vitesse) } override func update(_ currentTime: TimeInterval) { / if background.position.x <= -self.frame.size.width { background.position.x
