Connecting buttons in main storyboard to @IBAction func operate() in ViewController

I'm new to Swift and is trying out the beginner's project of building a calculator. The image below shows what stage I am up to.

However, I have just noticed that every single one of my operator buttons (except ÷) are not connected to the @IBAction func operate(sender: UIButton){}. How to connect those buttons to the @IBAction func operate(sender: UIButton){}?

enter image description here

In Swift 3, you'd like to change the @IBAction's argument from default (_ sender: Any) to (_ sender: UIButton) or (_ sender: AnyObject), but manually.

It might work.

You can check what outlets your buttons are connected to by right clicking on them. To connect a button to an action, hold down control while clicking and dragging from the button to the action you want to attach it to.
