Can I create custom Annotation in Swift?

Question

I know there are limited ways to create own custom Annotations in Java. One article describes here a way. I wonder, is it possible to create custom Annotation in Swift as well? For example, I have a BaseViewController and I want to test if any of its subclass created added annotation to log function names or not.

class BaseViewController: ViewController {

    func viewWillAppear() {
        // want to get if annotation added from caller and use
        super.viewWillAppear()
    } 
}

class SubViewController: BaseViewController {

    @LogEntrance    // custom annotation
    func viewWillAppear() {
        super.viewWillAppear()
    } 
}

If there is no way to use like it, How can I controller it otherwise? any workaround?

^{Context - I would be needing this for my large scale Swift app. I am using logger but I want to give developers flexibility to log classes, functions entrance and exits. Currently developers are putting logs at the entrance and exits of their functions and I want to give them annotation if possible.}
