Fun Facts App

What is wrong with this code? Xcode says the problem is in this line; let factProvider = factProvider(). Also, there is a problem in the last two lines.

// // ViewController.swift // Fun Facts // // Created by Macbook air 11 on 12/16/16. // Copyright © 2016 Macbookair11. All rights reserved. //

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var funFactLabel: UILabel!
let factProvider = factProvider()

override func viewDidLoad() {
    super.viewDidLoad()

    funFactLabel.text = factProvider.randomFact()
    }

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
    }

    @IBAction func showFact() {
   funFactLabel.text = factProvider.randomFact()
    let newColor = UIColor(red: 223/255.0, green: 86/255.0, blue: 94/255.0, alpha: 1.0)

        view.backgroundColor = randomColor
        funFactButton.tintColor = randomColor

}

}

Just a couple of questions

  1. Where did you get the factProvider() object from? Are you sure you have the correct name and not "FactProvider()"
  2. Where did you get the property "randomColor" from? Or was this a mistake and it suppose to be "newColor"
