Replace Gradient colors with ThemeSwift library (Library used for App Theme management)

Question

How to use this library for gradient colors as they haven't mentioned the usage of gradient with ThemeAnyPicker in their documentation.

I am using plist method which is much easier way than the other one. (This library can be used in 2 ways : Index method and Plist method)

Theme library link : https://github.com/wxxsw/SwiftTheme

I have given the code below.

@IBDesignable class GradientView: UIView {
    

    override class var layerClass: AnyClass {
        return CAGradientLayer.self
    }

    override func layoutSubviews() {
        
        // MARK: - Default gradient (Without applying Swift theme library)
        (layer as! CAGradientLayer).colors = [topColor.cgColor, bottomColor.cgColor]
        
        // MARK: - With Swift Theme library applied
        (layer as! CAGradientLayer).theme_colors =  // What should be the code here?
        
    }
}

Listen for color changes and reset the color of the drawing in the callback
