Animation finishes immediately, regardless of duration and delay

I have this animation block, but the cell background color is clear immediately:

cell.mylabel.backgroundColor = .orange
UIView.animate(withDuration: 3.0, delay:3, animations: {
    cell.mylabel.backgroundColor = .clear
})

The point is I am running this in cellForRowAt

I tried moving animation to my custom cell, but no success again:

override func didMoveToWindow() {
            UIView.animate(withDuration: 3.0, delay:3, animations: {
                self.mylabel.backgroundColor = .clear
            })
    }

That is too early, because the cell may not be in the on-screen view hierarchy yet. You can only animate a view that's in the on-screen view hierarchy. You need to find a way to add the animation after the cell has been added as a subview of the table view.

I would create a custom UITableViewCell subclass. In the subclass, I would override didMoveToWindow to add the animation to self.

Alternatively, it might work to override viewDidLayoutSubviews in the table view controller (if it has one), and add the animation in that method.

Try like this,

cell.mylabel.layer.backgroundColor = UIColor.redColor().CGColor
UIView.animate(withDuration: 3.0, delay:3, animations: {
    cell.mylabel.layer.backgroundColor = UIColor.clearColor().CGColor
})
