Fun Facts app - for loop help

Hi all,

I am modifying the Fun Facts starter app a little bit. I'd like to pass through my array every time the button is pressed.

struct WorkoutBook {
    let workoutArray = [
        "500",
        "600",
        "800",
        "300",
        "Pull"
    ]

    func doWork() -> String {
        for workout in workoutArray {
            return workout
        }
}

First could you please elaborate just a bit more about what exactly are you trying to accomplish. Also your Array doesn't quite make sense to me (perhaps it might once you explained your intent in more detail), but it's possible that you would be better off using a dictionary as opposed to an array, however I still don't know what the program task is exactly so I can't be certain.

Hey Kyle, Thanks for the reply. I would like to display one index in the array (in order), every time the button is pressed. The example Fun Facts app uses the ark4random_uniform function. Instead of randomly iterating through the array, I would rather iterate through all the index in order. Please let me know if you need more clarification. Thanks, Fares
