How to pass the gradient colors as a variable

[alamodey]

Hi,

I am trying to incorporate this code into my project and I am having trouble changing the colors so that it's not always grey and orange. Is it possible to edit this code anywhere so it'll accept variables for the colors:

//MARK: Private Methods
   private lazy var gradient: CAGradientLayer = {
       let gradientLayer = CAGradientLayer()
       gradientLayer.colors = [UIColor.darkGray.cgColor, UIColor.orange.cgColor]
       gradientLayer.startPoint = CGPoint(x: 0, y: 0)
       gradientLayer.endPoint = CGPoint(x: 1, y: 1)
       gradientLayer.frame = self.bounds
       return gradientLayer
   }()

How do I call this from my controller with variable colors?
