Adding button programmatically swift

I am trying to add button programmatically, I created button, it shows in app, but problem that when I write .addTarget in #selector occurs error (it builds successfully, but action do not work) I tried to write playAction() and playAction(sender:) and playAction. None of them work. enter image description here

playPauseButton.addTarget(self, action: #selector(playAction(sender:)), for: .touchUpInside)

@objc
func playAction(sender: UIButton){
    print("Hello")
}

UPD: I solved by creating just system button and changed it. Maybe my Xcode have bug and because of that occurs error.

Solution

  • Change with

    playPauseButton.addTarget(self, action: #selector(playAction), for: .touchUpInside)

    this is ok:

    @objc
func playAction(sender: UIButton) {
      print("Hello")
}

    works for me
