Changing of button title in iOS with swift 3 not working

I am trying to change the title of a button using setTitle

I am getting no errors and my IBAction is working but nothing happens.

What am I missing here?

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var hourTimerButton: UIButton!

    @IBAction func hourTimerButton(_ sender: Any) {
        hourTimerButton.setTitle("test", for: [])
        print("button")
    }   

    override func viewDidLoad() {
        super.viewDidLoad()

        hourTimerButton.setTitle("test", for: .normal)
        hourTimerButton.setTitle("test", for: [])    
    }
}

Try it this way:

Title1 and Title2 are two different titles for your UIButton:

Change @IBAction func hourTimerButton(_ sender: Any) to 

@IBAction func hourTimerButton(_ sender: AnyObject)

and then do this:

if (sender.currentTitle == "Title1"){
                button.setTitle("Title2", for: .normal)
            }

Hope it works!

Check your button(hourTimerButton) references are properly connected, I have debugged your code now, everything is working fine. Better you can change sender type as UIButton instead of Any. 

import UIKit

class ViewController: UIViewController {

  @IBOutlet weak var hourTimerButton: UIButton!

  @IBAction func hourTimerButton(_ sender: UIBUtton) {
      sender.setTitle("test", for: .normal)
      print("button")
  }   

  override func viewDidLoad() {
      super.viewDidLoad()
      hourTimerButton.setTitle("test", for: .normal)   
  }
}

Thanks.

Try setting button like this for normal state.

hourTimerButton.setTitle("test", for: .normal)
