Also I am creating a fact app that I want to generate strings in my array in the exact order that I have typed them, in each time my funFactLabel.text button is pressed I want the new fact to appear in the order it is typed. I have also created a struct to store my array properly. Can someone tell me what is wrong with my code please!

Swift

 import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var funFactLabel: UILabel!
        let factBook = FactBook()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        funFactLabel.text = factBook.factsArray[0]
    }

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



    @IBAction func showFunFact() {
        funFactLabel.text = sortInPlace factBook.factsArray[1]

    }

Try this, it should start at [1] for you.

funFactLabel.text = factBook.factsArray.sortInPlace()

Hello! Tank you so much for assisting me! These are the errors I am receiving after implenting the code you just suggested.

import UIKit

class ViewControllervarIViewController { @IBOutlet weak var funFactLabel: UILabel! let factBook = FactBook()

! override func viewDidLoad() {  (METHOD DOES NOT OVERRIDE ANY METHOD FROM ITS SUPERCLASS)
  !  super.viewDidLoad()  ('SUPER' METHODS CANNOT BE REFERENCED IN A ROOT CLASS)
    // Do any additional setup after loading the view, typically from a nib.
    funFactLabel.text = factBook.factsArray[0]
}

! override func didReceiveMemoryWarning() { (METHOD DOES NOT OVERRIDE ANY METHOD FROM ITS SUPERCLASS) ! super.didReceiveMemoryWarning() ('SUPER' METHODS CANNOT BE REFERENCED IN A ROOT CLASS) // Dispose of any resources that can be recreated. }

@IBAction func showFunFact() {
    funFactLabel.text = factBook.factsArray.sortInPlace()
                                                                        (CANNOT USE MUTATING MEMBER ON IMMUTABLE VALUE: 'factsArray' is a 'let' constant
}

}

Have you simply tried to do this? I have never used sorting before as I am new to iOS but I am trying to help out with the best of my knowledge.

factBook.factsArray.sort()
