Unfortunately, there isn't a way to add an action on tap outside of the MessageView.

However, if your dimMode is interactive (has tap outside to dismiss enabled) you can easily catch .willHide and .didHide events using eventListeners of SwiftMessages.Config:

let view = MessageView.viewFromNib(layout: .cardView)

var config = SwiftMessages.defaultConfig
config.dimMode = .gray(interactive: false)
config.eventListeners.append { event in
    switch event {
    case .willHide:
        // Handle will hide
    case .didHide:
        // Handle did hide
    default:
        break
    }
}
SwiftMessages.show(config: config, view: view)

Those events will be triggered on tap outside of the MessageView.

Update: In your particular case where you have a button which have a different action from the tap outside action, you can use something like this:

func showMessageView(buttonHandler: @escaping () -> Void, dismiss: @escaping () -> Void) {
    var buttonTapped = false
    let view = MessageView.viewFromNib(layout: .cardView)
    view.buttonTapHandler = { sender in
        buttonHandler()
        buttonTapped = true
    }

    var config = SwiftMessages.defaultConfig
    config.dimMode = .gray(interactive: false)
    config.eventListeners.append { event in
        if !buttonTapped, event == .didHide {
            dismiss()
        }
    }
    SwiftMessages.show(config: config, view: view)
}

That way when the button is tapped the dismiss closure will never run.
