Seem to have multiple values in label

I seem to have multiple values in the label value when generating a fact. This doesn't happen every time.

Heres my code.

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var funFactLabel: UILabel!

    let factProvider = FactProvider()

    override func viewDidLoad() {
        super.viewDidLoad()
        funFactLabel.text = factProvider.randomFact()  
    }

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

    @IBAction func showFact() {  
        funFactLabel.text = factProvider.randomFact()  
    }
}
import UIKit

struct FactProvider {

    let facts = [
        "Ants stretch when they wake up in the morning.",
        "Ostriches can run faster than horses.",
        "Olympic gold medals are actually made mostly of silver.",
        "You are born with 300 bones; by the time you are an adult you will have 206.",
        "It takes about 8 minutes for light from the Sun to reach Earth.",
        "Some bamboo plants can grow almost a meter in just one day.",
        "The state of Florida is bigger than England.",
        "Some penguins can leap 2-3 meters out of the water.",
        "On average, it takes 66 days to form a new habit.",
        "Mammoths still walked the Earth when the Great Pyramid was being built."
    ]

    func randomFact() -> String{

        let randomNum:UInt32 = arc4random_uniform(9)
        let randomInt:Int = Int(randomNum)
        print(facts[randomInt])
        return facts[randomInt]  
    }
}
