            eventId: eventId
        )
        
        // Display basic event info
        print("Event: \(event.title)")
        print("Type: \(event.eventType)")
        print("Created by: \(event.createdBy?.name ?? "Unknown")")
        
        if let description = event.description {
            print("Description: \(description)")
        }
        
        if let location = event.location {
            print("Location: \(location)")
        }
        
        if let startTime = event.startTime {
            let formatter = DateFormatter()
            formatter.dateStyle = .medium
            formatter.timeStyle = .short
            print("When: \(formatter.string(from: startTime))")
        }
        
        // Process metadata based on event type
        if let metadata = event.metadata {
            switch event.eventType {
            case "photo", "post":
                if let imageUrl = metadata["imageUrl"] {
                    print("Image: \(imageUrl)")
                }
                
            case "activity":
                if let actionType = metadata["actionType"] {
                    print("Action: \(actionType)")
                }

                // Display all metadata for other event types
                for (key, value) in metadata {
                    print("\(key): \(value)")
                }

Working with Event Feeds

The SDK provides several feed types for accessing events:
  • Following Feed: Events from users the current user follows
  • “For You” Feed: Public events from the wider network
  • Upcoming Events: Events scheduled in the future
  • User Events: Events created by a specific user
These feeds enable creation of rich social experiences within your app.
