Getting an error with my button

Here is my view controller:

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var funFactLabel: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()

        funFactLabel.text = "An interesting fact"
    }

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


    @IBAction func showFact() {
        let facts = ["Ants stretch when they wake up in the morning", "Ostriches can run faster than horses"]

        funFactLabel.text = facts[1]
    }

}

And here is the error:

2016-11-23 11:12:13.838 FunFacts[27083:4301691] -[FunFacts.ViewController showFact]: unrecognized selector sent to instance 0x7f9f76f056f0

Well I figured it out :) For some reason I had two actions attached to the button but it seems to have resolved it self after I removed the duplicate.
