How to get the current Title of a button in Swift 3.0 , ios using sender.titleForState(.Normal)!

Because parameter sender is in type Any instead of UIButton. Change the method signature to:

@IBAction func buttonAction(_ sender: UIButton) {
  if let buttonTitle = sender.title(for: .normal) {
    print(buttonTitle)
  }
}

and you should be good to go.

To get the title of the button regardless of its current state in swift 3.0 try using this:

    @IBAction func buttonPressed(_ sender:UIButton){
       let buttonTitle = sender.titleLabel?.text
       print("\(String(describing: buttonTitle)")
    }

This will return the title for the state, based on the state that the button is current in.

Smartest version using Swift 5.0:

@IBAction func buttonAction(_ sender: UIButton) {
    print(sender.currentTitle)
}
