How Do I Initialize the iOS SDK (v3)?

import UIKit
import Gameball

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        
        let config = GameballConfig(
            apiKey: "your-api-key",          // Required
            lang: "en"                       // Required
        )
        
        GameballApp.getInstance().`init`(config: config) { error in
            if let error = error {
                print("Gameball init failed: \(error.localizedDescription)")
            }
        }
        
        return true
    }
}

        }
    }
