Игрок проходит через платформу

функция игрока

@objc func playerFunction(){
    
    player = SKSpriteNode(imageNamed: "Player")
    player.name = "Hero"
    player.size = CGSize(width: 80, height: 80)
    player.physicsBody = SKPhysicsBody(rectangleOf: player.size)
    player.physicsBody?.affectedByGravity = false
    player.physicsBody?.isDynamic = false
    player.physicsBody?.allowsRotation = false
    player.physicsBody!.categoryBitMask = 1
    player.physicsBody!.collisionBitMask = 0
    player.physicsBody!.contactTestBitMask = 2 | 5 | 6 | 7
    player.physicsBody?.velocity.dx = 0
    player.physicsBody?.velocity.dy = 0
    player.zPosition = 1
    player.position = CGPoint(x: self.frame.width / 2 - 700, y: self.frame.height / 2 - player.frame.height)
    self.addChild(player)
    
}

платформенный метод

@objc func platformFunction (){

    platform_One = SKSpriteNode(imageNamed: "Platform")
    platform_One.physicsBody = SKPhysicsBody(rectangleOf: platform_One.size)
    platform_One.physicsBody?.affectedByGravity = false
    platform_One.physicsBody?.isDynamic = false
    platform_One.zPosition = 4
    platform_One.position = CGPoint(x: 1 + self.frame.width / 2 - 570, y: self.frame.height / 2 - 260)
    self.addChild(platform_One)
    
    
    platform_Two = SKSpriteNode(imageNamed: "Platform")
    platform_Two.physicsBody = SKPhysicsBody(rectangleOf: platform_Two.size)
    platform_Two.physicsBody?.affectedByGravity = false
    platform_Two.physicsBody?.isDynamic = false
    platform_Two.physicsBody!.categoryBitMask = 7
    platform_Two.physicsBody!.collisionBitMask = 1
    platform_Two.physicsBody!.contactTestBitMask = 1
    platform_Two.zPosition = 5
    platform_Two.position = CGPoint(x: 1 + self.frame.width / 2 - 420, y: self.frame.height / 2 - 260)
    self.addChild(platform_Two)

Метод игрока и код метода платформы добавлены выше, и игрок не приземляется на платформу, вместо этого игрок проходит через платформу, хотя физика была указана выше.
