Assigning color output to if else statements

Like the example here with playing cards. If I instead wanted to output a specific color (visually) to the console instead of a number, how would I go about doing that?

I am not sure what you are asking, because the console can not print colors its like a CMD line, just black and white text.

If you can specify im sure I can help

I'm in the beginning stages of programming an app that has visual indicators of various colors depending on the output of variables. Just looking for general advice on ways to accomplish this

I am not sure in the the way you want your variables and I ma going to assume you have to a view that you can alter. Although if it was a label or text view it would work in the same manner. But here is a working swift program i type in 2 seconds that depending on what totalNumber is equal to, depends on the colour of the background of the view.

//
//  ViewController.swift
//  colourChange
//

import UIKit

class ViewController: UIViewController {

    var firstNumber = 2
    var secondNumber = 3

    override func viewDidLoad() {
        super.viewDidLoad()

        var totalNumber = firstNumber + secondNumber

        if totalNumber == 5 {
            self.view.backgroundColor = UIColor.blueColor()
        }else{
            self.view.backgroundColor = UIColor.greenColor()
        }
    }
}

you can simply just copy and paste this into a empty swift file in a project or I have uploaded this to GitHub if you want to look at it that way, just download the zip and open up: https://github.com/dombryan94/colourChange

Hope this helps, ask if you want anything else and remember to mark this up for others to see (and it helps me out a lot) :)

Thanks
