How to use

In your UIViewController class add NotificationCenter observers with the Notification.Name from the available player event list with TargetVideoPlayer as the observer's object. Here is example of two observers setup to listen for .playerInitialized and .adImpression.

    private func setupNotificationObeservers() {
        NotificationCenter.default.addObserver(self, selector: #selector(handlePlayerInitializedNotification), name: .playerInitialized, object: player)
        NotificationCenter.default.addObserver(self, selector: #selector(handleAdImpressionNotification), name: .adImpression, object: player)
    }
    
    @objc private func handlePlayerInitializedNotification() {
        // Handle the playerInitialized notification
    }
    
    @objc private func handleAdImpressionNotification() {
        // Handle the adImpression notification
    }

Notifications that send data

Some notifications like .getCurrentIndex, .getDuration, .getCurrentTime. , etc. Contain data in their userInfo dictionary with key "playerEvents".

 NotificationCenter.default.addObserver(self, selector: #selector(handleDataNotification), name: .getVideo, object: player)

@objc private func handleDataNotification(_ notification: Notification) {
    if let currentVideoData = notification.userInfo?["playerEvents"] as? VideoData {
        // Handle the data recieved with notification
    }
}
