I am getting an error message "variable used within its own initial value" import UIKit class ViewC

import UIKit

class ViewController: UIViewController {

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

override func viewDidLoad() {
    super.viewDidLoad()
    funFactLabel.text = factModel.getRandomFact()
}

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

@IBAction func showFunFact() {
    let randomColor = ColorModel().getRandomColor()
    view.backgroundColor =  randomColor
    funFactButton.tintColor = randomColor
  funFactLabel.text = factModel.getRandomFact()
}

It looks like your third loin should read let factModel = FactModel() Try that.
