我正在尝试创建一个for循环,但似乎无法理解如何摆脱这个错误

我的代码:

for i:CGFloat in 0 ..< 2 + self.frame.size.width / (movingGroundTexture.size().width) { 
        let sprite = SKSpriteNode(texture: movingGroundTexture)
        sprite.zPosition = 0
        sprite.anchorPoint = CGPointMake(0, 0)
        sprite.position = CGPointMake(i * sprite.size.width, 0)
        addChild(sprite)
    }

错误for在线self.frame.size.width和(movingGroundTexture.aize().width)
