Save an array of colors to User Defaults

Save an array of colors to User Defaults - iOS Swift 2.3

I am wondering how to save an array of UIColors to user default.

I have the following code to save a single UIColor to user defaults, does anyone know how to modify this to allow me to store arrays of UIColor in NS User Defaults?

extension NSUserDefaults {

    

    func colorForKey(key: String) -> UIColor? {

        var color: UIColor?

        if let colorData = dataForKey(key) {

            color = NSKeyedUnarchiver.unarchiveObjectWithData(colorData) as? UIColor

        }

        return color

    }

    

    

    

    func setColor(color: UIColor?, forKey key: String) {

        var colorData: NSData?

        if let color = color {

            colorData = NSKeyedArchiver.archivedDataWithRootObject(color)

        }

        setObject(colorData, forKey: key)

    }

    

}

You can do it in following way

let colors = [UIColor.whiteColor(), UIColor.greenColor()] // Array of colors

NSUserDefaults.standardUserDefaults().setObject(NSKeyedArchiver.archivedDataWithRootObject(colors), forKey: "ColorsKey") //For saving in NSUserDefaults

//For retrieving use following 

let decodedColorsData  = NSUserDefaults.standardUserDefaults().objectForKey("ColorsKey") as! NSData

let colorsArray = (NSKeyedUnarchiver.unarchiveObjectWithData(decodedColorsData) as! NSArray) as Array

Swift 4.2: Saving and loading colours / colours to user defaults
note: the load from defaults works but contains a deprecated item which does not yet have a good worked example to replace it.

               let colorToSetAsDefault : UIColor = view.backgroundColor!

                do

                {

                    let data : NSData = try NSKeyedArchiver.archivedData(withRootObject: colorToSetAsDefault,requiringSecureCoding: false) as NSData

                    UserDefaults.standard.set(data, forKey: "userHeadingColor") // your key in quotes

                    UserDefaults.standard.synchronize()

                } // end of do

                catch

                {

                    print("Couldn't save color")

                }  // end of catch



            // load the color back as a test to make sure the save has worked

            if let colorObject = UserDefaults.standard.object(forKey: "userHeadingColor")

            {

                let colorData = colorObject as! NSData

                let color = NSKeyedUnarchiver.unarchiveObject(with: colorData as Data) as? UIColor

                // replace with unarchivedObjectOfClass:fromData:error:

                self.testDefaultsView.backgroundColor = color

            }

            else
