Button won't unhide

I can get my buttons to hide, but not unhide.

I hide the answerOneCover button on tap with:

@IBAction func answerOneCoverTapped(_ sender: Any) {
    animateButtonCoverOut(button: answerOneCover)
}

func animateButtonCoverOut(button: UIButton) {

    UIView.animate(withDuration: 1.0, delay: 0.1, options:
        UIViewAnimationOptions.curveEaseOut, animations: {
            button.alpha = 0
    }, completion: { finished in
        button.isHidden = true
    })
}

And I try to unhide the answerOneCover button when a different button, answerOneButtonText button is tapped:

@IBAction func answerOneButtonTextTapped(_ sender: Any) {
    answerOneCover.isHidden = false
}

But I can't get answerOneCover to unhide. Is there any way to do this that I'm missing?

You have to set the buttons Alpha back to 1. change your code to look like this:

@IBAction func answerOneButtonTextTapped(_ sender: Any) {
    answerOneCover.alpha = 1
    answerOneCover.isHidden = false
}

OR you can put it in your animations completion like so: 

func animateButtonCoverOut(button: UIButton) {

    UIView.animate(withDuration: 1.0, delay: 0.1, options:
        UIViewAnimationOptions.curveEaseOut, animations: {
            button.alpha = 0
    }, completion: { finished in
        button.isHidden = true
        button.alpha = 1
    })
}
