The button "Show Another Fun Fact" is not changing the color!

@IBAction func showFunFact() {

    let randomColor = colorWheel.randomColor()
    // This calls a random color and then sets it to the variable randomColor

    view.backgroundColor = randomColor

    funFactButton.tintColor = randomColor
    // This now sets both of the above color aspects to the color generated through 'randomColor'.

    funFactLabel.text = factBook.randomFact()

Hey, good to see you again! :)

I think the problem you have is within the showFunFact() method that you're calling.

Looks like it's just where you have placed the '=' assignment operator.

Firstly, to make your code more concise and to get the text to match the background colour, try assigning the random colour method to a variable called randomColor, then assign that to 'view.backgroundColor' and 'funFactButton.tintColor', as below.

@IBAction func showFunFact() {

var randomColor = colorWheel.randomColor()
// This calls a random color and then sets it to the variable randomColor

view.backgroundColor = randomColor

funFactButton.tintColor = randomColor
// This now sets both of the above color aspects to the color generated through 'randomColor'.

funFactLabel.text = factBook.randomFact()

}

Hope this helps!!

You may have to delete my comments for this to work.
