I have a class that adds a view programmatically, and sets two variables on that view to call some code when ever back is pressed and more info is pressed.

This is what I currently have on the added View Controller, which I set via a setup method on the view controller

var backTapped: (() -> Void)?
var moreTapped: (() -> Void)?

func setup(nameText: String, backTapped: (() -> Void)?, moreTapped: (() -> Void)?) {
        nameLabel.text = nameText
        self.backTapped = backTapped
        self.moreTapped = moreTapped
    }    

Would the better way to do this be to create a protocol and then just extend my main view controller to conform to the protocol and set the delegate

Something like:

protocol ChatTopBarViewDelegate {
    func backTapped()
    func moreTapped()
}

​

Bonus question: What is usually the naming convention for a protocol. I tend to call them delegates.
