Use Variable in viewDidLoad

Question

The Label etikett1 does output the value of variable test1 correctly, but the Label etikett2 is not working. How I can get the value of variable test2 declared in viewDidLoad?

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var etikett1: UILabel!
    @IBOutlet weak var etikett2: UILabel!

    @IBAction func button(sender: UIButton) {
        let test1 = "hello 1"
        etikett1.text = test1  
        etikett2.text = test2       
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        let test2 = "hello 2"
    }
}

Answer 1

You need to either declare test2 as an instance variable, alongside your two labels, or assign the text property of etikket2 inside viewDidLoad:

Method 1:

class ViewController: UIViewController {
    @IBOutlet weak var etikett1: UILabel!
    @IBOutlet weak var etikett2: UILabel!
    let test2 = "hello 2"

    @IBAction func button(sender: UIButton) {
        let test1 = "hello 1"
        etikett1.text = test1  
        etikett2.text = test2       
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

Method 2:

override func viewDidLoad() {
    super.viewDidLoad()
    let test2 = "hello 2"
    etikett2.text = test2
}
