Swift : Animate width and height of UIButton

Inside of these two functions, I want to animate the button shrinking(gone), then animate it growing(seen). I was able to animate it growing, but not at first have the button shrink. Any help on how to animate a button shrinking?

func progressBarButtonFadeOut(){
    UIView.animateWithDuration(0.2, animations: {
    //timeCapDesign is a UIButton
        self.timeCapDesign.transform = CGAffineTransformMakeScale(0, 0)

    })
}

//Progress Bar Fade In Buttons
func progressBarButtonFadeIn(){
    UIView.animateWithDuration(0.2, animations: {

        self.timeCapDesign.transform = CGAffineTransformIdentity

    })
}

got it. So what i had to do was this:

func progressBarButtonFadeOut(){
UIView.animateWithDuration(0.2, animations: {
//timeCapDesign is a UIButton

    self.timeCapDesign.alpha = 0

    self.timeCapDesign.transform = CGAffineTransformMakeScale(0.1, 0.1)

})
}

//Progress Bar Fade In Buttons
func progressBarButtonFadeIn(){
UIView.animateWithDuration(0.2, animations: {

    self.timeCapDesign.alpha = 1

    self.timeCapDesign.transform = CGAffineTransformIdentity

})
}

So ultimately to shrink it i set it to a value of the CGAffineTransformMakeScale really low such as (0.1,0.1) and then animated the alpha to 0 to give the effect that its shrinking to nothing.

The scale of "1" is the current size, and if you want to animate it growing, the number should be bigger than 1.

func progressBarButtonFadeOut(){
UIView.animateWithDuration(0.2, animations: {
//timeCapDesign is a UIButton
    self.timeCapDesign.transform = CGAffineTransformMakeScale(1.5, 1.5)

})

}
