Animating view colour changes

Published on · Updated on

When animating the addition of cells to a UICollectionView, we may notice that text and background colours aren't animating when using UIView.animate. Using UIView.transition instead works perfectly!

UIView.transition(with: commentContainer, duration: 0.6,
                  options: .transitionCrossDissolve, animations: {
   commentContainer.backgroundColor = UIColor(red: 17, green: 215, blue: 198)

UIView.transition(with: commentLabel, duration: 0.6,
                  options: .transitionCrossDissolve, animations: {
   commentLabel.textColor = UIColor(red: 143, green: 155, blue: 174)
