Animations going in reverse

[alanscarpa]

I have a label on my xib with auto layout constraints centering it vertically and horizontally. I just want to move my label to the right, like in your example code:

UIView.animateWithDuration(2.0, animations: {
            self.label.layer.position.x = 200.0
        }) 

But when I run this, my label loads on the screen, off to the right and then animates back to the center. It's the opposite of what I would expect.

Is this due to the layout constraints?

It was because I was executing this code in viewDidLoad. viewDidAppear works because constraints are set up at this point.
