I am trying to move my collection view vertically 5px at a time using content offset using time interval trigger but it's not animating, my code for that is 

timer = Timer.init(timeInterval: 1.0, target: self, selector: #selector(animateScroll), userInfo: nil, repeats: true)

@objc func animateScroll() {
    self.previousOffset = self.collectionView.contentOffset.y
    self.collectionView.contentOffset.y = self.previousOffset + 5
}
