Get started

This is not all steps required for Adapty to work, just some useful tips for integration with Firebase. If you want to integrate Adapty in you app, you should read Quickstart Guide first

User Identification​

If you're using Firebase auth, this snippet may help you keep your users in sync between Firebase and Adapty. Note that it's just an example, and you should consider your app auth specifics.

import Adapty
import Firebase
 
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
 
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Configure Adapty before Firebase
        Adapty.activate("YOUR_API_KEY")
        Adapty.delegate = self
        
        // Configure Firebase
        FirebaseApp.configure()
        
        // Add state change listener for Firebase Authentication
        Auth.auth().addStateDidChangeListener { (auth, user) in
            if let uid = user?.uid {
                // identify Adapty SDK with new Firebase user
                Adapty.identify(uid) { error in
                    if let e = error {
                        print("Sign in error: \(e.localizedDescription)")
                    } else {
                        print("User \(uid) signed in")
                    }
                }
            }
        }
 
        return true
    }
 
}
 
extension AppDelegate: AdaptyDelegate {
 
    // MARK: - Adapty delegate
    func didReceiveUpdatedPurchaserInfo(_ purchaserInfo: PurchaserInfoModel) {
        // You can optionally post to the notification center whenever
        // purchaser info changes.
 
        // You can subscribe to this notification throughout your app
        // to refresh tableViews or change the UI based on the user's
        // subscription status
        
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "com.Adapty.PurchaserInfoUpdatedNotification"), object: purchaserInfo)
    }
 
}
