Seem to have multiple values in label

import UIKit

    @IBOutlet weak var funFactLabel: UILabel!

    let factProvider = FactProvider()

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func didReceiveMemoryWarning() {

        // Dispose of any resources that can be recreated.
    }

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

import UIKit

    let facts = [
        "Ants stretch when they wake up in the morning.",
