I am trying to animate UILabel textColor changes using UIView.animate. However, nothing is changing when I attempt to use UIView. Here is my code:

titleLabel.textColor = UIColor(red: 104/250, green: 155/250, blue: 121/250, alpha: 1)
UIView.animate(withDuration: 1.0, animations: {
 self.titleLabel.textColor = UIColor(red:206/255, green: 206/255, blue: 206/255, alpha: 1.0)

I expect the color of the label to change to a greenish color and then change back to the gray-ish color it was before. Thanks in advance for helping!

The textColor property is not specified as being animatable in Apple developer docs, so I don't think you can do it with a simple UIView animations block.

You can use UIView transition instead.

Code:

UIView.transition(with: self.titleLabel, duration: 1.0, options: .transitionCrossDissolve, animations: 
 self.titleLabel.textColor = UIColor(red: 104/250, green: 155/250, blue: 121/250, alpha: 1)
 , completion: _ in
 self.titleLabel.textColor = UIColor(red:206/255, green: 206/255, blue: 206/255, alpha: 1.0)
 )

I hope it will help you. Let me know if you are still having any issue.
