Get the inverted color for a particular color iOS swift

 Solution:

extension UIColor {

    func inverseColor() -> UIColor {

        var alpha: CGFloat = 1.0

        

        var red: CGFloat = 0.0, green: CGFloat = 0.0, blue: CGFloat = 0.0

        if self.getRed(&red, green: &green, blue: &blue, alpha: &alpha) {

            return UIColor(red: 1.0 - red, green: 1.0 - green, blue: 1.0 - blue, alpha: alpha)

        }

        

        var hue: CGFloat = 0.0, saturation: CGFloat = 0.0, brightness: CGFloat = 0.0

        if self.getHue(&hue, saturation: &saturation, brightness: &brightness, alpha: &alpha) {

            return UIColor(hue: 1.0 - hue, saturation: 1.0 - saturation, brightness: 1.0 - brightness, alpha: alpha)

        }

        

        var white: CGFloat = 0.0

        if self.getWhite(&white, alpha: &alpha) {

            return UIColor(white: 1.0 - white, alpha: alpha)

        }

        

        return self

    }
