In the default Kotlin/native AppCode application demo, I see the following code snippet:

@ObjCAction
    fun buttonPressed() {
        label.text = "Konan says: 'Hello, ${textField.text}!'"
    }

It's not clear how the

@ObjCAction

is routing to the button that's being pressed. It's also not clear how that button is being selected. Can anyone point me in the right direction?

This relationship is established in the storyboard:

<connections>
  <action selector="buttonPressed" destination="BYZ-38-t0r" eventType="touchUpInside" id="frh-jo-ppG"/>
</connections>

This can also be done programmatically: https://developer.apple.com/documentation/uikit/uicontrol/1618259-addtarget?language=objc

Thanks 🙂

Looks like it's Kotlin version of

@IBAction
