How can I implement Presets savings in Tableview

I need help I have these ColorSlider App that change the color of Square with 3 sliders RGB .I like to create a Tableview where i can store presets of color and retrieve from preset name e.g. Ocean Blue, Emerald Green, Red Ferrary etc. I create The Tableview with the push of the button but I am stuck with the rest of implementation. Please I need help.

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var redSlider: UISlider!
@IBOutlet weak var greenSlider: UISlider!
@IBOutlet weak var blueSlider: UISlider!
@IBOutlet weak var displaylbl: UILabel!
@IBOutlet weak var displayView: UIView!

var color:Color!

override func viewDidLoad() {
    super.viewDidLoad()

    color = Color(red: redSlider.value, green: greenSlider.value, blue: blueSlider.value)
    displaylbl.text = color.getString()
    displayView.backgroundColor = color.getColor()
}

@IBAction func sliderChanged(_ sender: UISlider) {
    if (sender.tag == 1){
        color.setRed(red: sender.value)
        displaylbl.text = color.getString()
        displayView.backgroundColor = color.getColor()
    }
    else if (sender.tag == 2) {
        color.setGreen(green: sender.value)
        displaylbl.text = color.getString()
        displayView.backgroundColor = color.getColor()
    }
    else if (sender.tag == 3) {
        color.setBlue(blue: sender.value)
        displaylbl.text = color.getString()
        displayView.backgroundColor = color.getColor()
    }
}

}

import UIKit

class Color { private var red:CGFloat private var green:CGFloat private var blue:CGFloat

init(red:Float, green:Float, blue:Float) {
    self.red = CGFloat(red)
    self.green = CGFloat(green)
    self.blue = CGFloat(blue)
}

func setRed(red:Float) {
    self.red = CGFloat(red)
}
func setGreen(green:Float) {
    self.green = CGFloat(green)
}
func setBlue(blue:Float) {
    self.blue = CGFloat(blue)
}

func getColor() -> UIColor {
    let color = UIColor(red: red/255, green: green/255, blue: blue/255, alpha: 1.0)

    return color
}
func getString() -> String {
    let string = "Red: \(Int(round(red)))\nGreen: \(Int(round(green)))\nBlue: \(Int(round(blue)))"
    return string
}

}

First you need to get the RGB color from slider and show in box, if you have done this part then now you need to do is whenever you are showing color in box you just make a dictionary with keys like :

let dict = [ colorName : "whatever you want",
             colorCode : "Which you get from slider"
           ]

Add it in array too like:

arrayColor.append(dic)

Populate your tableview from arrayColor array, and in didselectatindexpath you need to get colorCode atIndexPath.row and set in box.

Hope this will help you. For any other query comment below.
