Answer 1

For those of you using Swift 4, here's what I used for multiple objects to Glow the same color as they are:

let colorRed: UIColor? = timeLabel.textColor
timeLabel.layer.shadowColor = colorRed?.cgColor
timeLabel.layer.shadowRadius = 4.0
timeLabel.layer.shadowOpacity = 0.9
timeLabel.layer.shadowOffset = CGSize.zero
timeLabel.layer.masksToBounds = false

As for animating the glow, just add a timer for 3-4 loops and change .shadowOpacity to something lower.
