Sprite Kit and type inference

So I'm building a Sprite Kit game and at a certain point I want to enable/disable gravity on some of my nodes.

I managed to do it but I just was wondering if there is a better way to achieve this.

Here's my code:

func enableGravity() {
    for rawBubble in container!.children {
        let bubble = rawBubble as SKShapeNode
        bubble.physicsBody?.dynamic = true
    }
}

When not using type inference on rawBubble, I get this error : SKPhysicsBody? does not have a member named dynamic

I guess this is not really a Sprite Kit related issue but more Swift itself. Is it possible to do this in a more simple way?

Thanks.

Since container!.children is an [AnyObject], you're going to have to cast its contents before you can do anything all that useful with them. The cleanest way I can think of is just to cast it to a [SKNode] right in your for statement:

func enableGravity() {
    for bubble in container!.children as [SKNode] {
        bubble.physicsBody?.dynamic = true
    }
}
