how i can add animation to any UI by snapkit by swift 3?

Question

label.snp.makeConstraints { (make) -> Void in

        make.width.equalTo(box).dividedBy(2)

        make.top.equalTo(100)

        make.left.greaterThanOrEqualTo(box.snp.left).offset(15)
}

I want animate this label to another position by button

Answer 1

After you update your constraints call layoutIfNeeded() on your view in an animation closure.

    UIView.animateWithDuration(0.2, delay: 0, options: [], animations: { () -> Void in 
       self.view.layoutIfNeeded()
    })

Hope this helps.
