Animate titleView on button click

I'm new to animation in ios and i'm trying to apply an animation on the titleView in the navigationBar but following code keep saying: 

Cannot invoke 'animateWithDuration' with an argument list of type '(FloatLiteralConvertible, delay: FloatLiteralConvertible, options: UIViewAnimationOptions, animations: () -> () -> $T4, completion: (($T16) -> ($T16) -> $T15) -> (($T16) -> $T15) -> $T15)'

when i remove the 

self.navigationItem.titleView?.center = CGPointMake(10, 10)

there is no error, but how can i apply an animaiton on the titleView/title?

@IBAction func animateButtonTapped(sender: UIBarButtonItem) {



    UIView.animateWithDuration(0.7, delay: 1.0, options: UIViewAnimationOptions.CurveEaseOut, animations: {

        self.navigationItem.titleView?.center = CGPointMake(10, 10)

        }, completion: { finished in
            println("Basket doors opened!")
    })


}

UIView.animateWithDuration(0.7, delay: 1.0, options:.CurveEaseOut, animations: {
    // Optional chaining may return nil
    _ = self.navigationItem.titleView?.center = CGPointMake(10, 10)
    // return
    }, completion: {
        finished in
        println("Basket doors opened!")
})
