Fun Facts app error in ViewController

I am working on the Fun Facts app, and I am getting an error for my "var randomColor = ColorWheel.randomColor ()" and I don't know what I am doing wrong.

Thanks in advance for your help!

Remove the space between ColorWheel.randomColor and the constructor //()\

Post the code for the ColorWheel Struct? What error are you getting?

We need a bit more information then that.

Here is my complete code:

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var funFactLabel: UILabel!
@IBOutlet weak var funFactButton: UIButton!

let factBook = FactBook()
let colorWheel = ColorWheel()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    funFactLabel.text = factBook.randomFact()
}

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

@IBAction func showFunFact() {
    var randomColor = ColorWheel.randomColor ()
    view.backgroundColor = randomColor
    funFactButton.tintColor = randomColor
   funFactLabel.text = factBook.randomFact()
}

}

//**The error is showing up by "var randomColor"
