How to init a button in iOS?

Put one line in the right class:

    @IBOutlet var aButton: UIButton!

You can also do it by code. Here is an example

          var loginButton: UIButton
          loginButton = UIButton(frame: CGRect(x: 80, y: 30, width: 100, height: 30))
          loginButton.setTitle("Tweet", for: UIControl.State.normal) 
          loginButton.addTarget(self, action: #selector(buttonTweetAction), for: UIControl.Event.touchUpInside)
          view.addSubview(loginButton)     // Add the button to the view

thank you OOP for your help

Thank you Claude31. In particular for the additions you made. Manuals a very succinct and for occational programmers often no help. To much implicit information resp. abbreviations. More explanations or examples like the one you gave are needed.

Yes, unfortunately, documentation is often succint and assumes you know a lot. Not really good for beginners. That's why I used a lot ray Wandelich tutorials when I need to learn on a new area.

ANyway, I hope your problem is solved.

If so, don't forget to close the thread by marking the correct answer.

Hello Claude31,

thank you for your kind reply. One question remains but not important for the solution of my problem:
