EXTRA extra Credit for Refactoring into a Model

Ok so I have done all the extra credit so far, and one of the tasks involves changing the color of the Text label once the button is pressed. I wanted to create a new class and put this code into it (as it was done with the predictions array), but I am experiencing a problem since UIColor is not an instance recognized in my new class...

Any ideas on how to do this?

Alex,

You are on the right track. You need to create a 2nd ColorWheel

struct ColorWheelText {

//Make sure you use different colors... 
    let colorsTextArray = [
        UIColor(red: 90/255.0, green: 187/255.0, blue: 181/255.0, alpha: 1.0), //teal color
        UIColor(red: 222/255.0, green: 171/255.0, blue: 66/255.0, alpha: 1.0), //yellow color
        UIColor(red: 223/255.0, green: 86/255.0, blue: 94/255.0, alpha: 1.0), //red color
        UIColor(red: 239/255.0, green: 130/255.0, blue: 100/255.0, alpha: 1.0), //orange color
        UIColor(red: 77/255.0, green: 75/255.0, blue: 82/255.0, alpha: 1.0), //dark color
        UIColor(red: 105/255.0, green: 94/255.0, blue: 133/255.0, alpha: 1.0), //purple color
        UIColor(red: 85/255.0, green: 176/255.0, blue: 112/255.0, alpha: 1.0), //green color
    ]

    func randomColor() -> UIColor {

        var unsignedArraycount = UInt32(colorsTextArray.count)
        var unsignedRandomNumber = arc4random_uniform(unsignedArraycount)
        var randomNumber = Int(unsignedRandomNumber)

        return colorsTextArray[randomNumber]

    }

}

After that you can add the following line of code.

funFactLabel.textColor = colorsTextArray

Hope this helps.
