Just experimenting. Need some help.

after making a struct similar to the video, i wanted to experiment something. As am a bit familiar with FOR LOOP from prior experience, i used it in here to display all the values of the string one by one on each click of the button. But when I click the button, it jumps directly to the last value of the string. 

import UIKit

class ViewController: UIViewController {
var factModel = FactModel()
@IBOutlet weak var funFactLabel: UILabel!
override func viewDidLoad() {
    super.viewDidLoad()
    funFactLabel.text = factModel.facts[0]
}

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

@IBAction func showFunFact() {
    for fact in factModel.facts{
    funFactLabel.text = fact
    }
}
 }

tried using C for loop swell, but isn't working

import UIKit

class ViewController: UIViewController {
        var factModel = FactModel()
@IBOutlet weak var funFactLabel: UILabel!
override func viewDidLoad() {
    super.viewDidLoad()
    funFactLabel.text = factModel.facts[0]
}

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

@IBAction func showFunFact() {
    var i : Int
    for(i = 0; i<factModel.facts.count; i += 1){
        funFactLabel.text = factModel.facts[i]
    }
    }

}

I think the problem is inside your showFunFact(). If you want to append the string, you might want to try inside your loop the following code:

funFactLabel.text.stringByAppendingString(fact)
