Generate a random number?

What if i did not want to generate a random count for the array's. What if I only wanted to display the array's in order that they are written?

I made it this way:

I declared a variable at the top

     var elements: Int = 0

and then in the showFunFact function change the value of the variable to show the next array element 

    @IBAction func showFunFact() {
        if elements != (factModel.facts.count - 1){
            elements += 1
            funFactLabel.text = factModel.facts[elements]
        }
        else {
            elements = 0
            funFactLabel.text = factModel.facts[elements]
        }
    }

I hope it helps :)

you could do a For loop that would loop over each index of the array.

Example: 

for index in 0...array.count {
   // Do something
}
