Configure App Attest

First, you need to configure the Xcode project so that the SDK can use Apple’s App Attest API to ensure that requests sent from your app come from legitimate instances of your app.
  1. Add the App Attest capability for your app target.

     Add the App Attest capability
  2. Open the .entitlements file in your Xcode project and set the App Attest Environment value to $(ATTENV)

     Set the App Attest Environment value
  3. In Xcode’s Target Build Settings, create a user-defined setting named ATTENV and set its value to production for Release and development for Debug.

     Create a user-defined setting named ATTENV

​
Import the SDK Code

For SDK initialization, you can implement the App init method:
SwiftUI
import SwiftUI

@main
struct SwiftUIDemoApp: App {
    
    // Add this method                                                          
    init() {
        // Configure RevenueFlo
        RevenueFlo.configure()
    }
    
    var body: some Scene {
        WindowGroup {
            ContentView()
                .preferredColorScheme(.light)
        }
    }
}

​
Present an In-app Offer

In your ContentView, call the presentOffer() method to seamlessly present an exclusive offer to your users. Ensure to configure the offer details in the campaign dashboard before invoking.
SwiftUI
struct ContentView: View {

    @StateObject private var revenueFloDelegate = RevenueFloDelegateHandler()

    var body: some View {
        
        // Setup your UI
        VStack {
            Image(systemName: "gift")
                .imageScale(.large)
                .foregroundStyle(.tint)
            Text("RevenueFlo Demo!")

                .onAppear {
                    // Call the SDK method to seamlessly present an exclusive offer from the Revenueflo.
                    RevenueFlo.shared.showOffer(
                        delay: 5, delegate: revenueFloDelegate)
                }

            Button("Show Offer") {
                // RevenueFlo.shared.showOffer()
            }
        }
        .padding()
    }
}

class RevenueFloDelegateHandler: NSObject, RevenueFloActionDelegate,
    ObservableObject
{
    func offerDidPresent(_ offer: String) {
        print("Offer presented: \(offer)")
    }

    func offerDidClose(_ offer: String) {
        print("Offer closed: \(offer)")
    }

    func offerPrimaryButtonDidClick(_ offer: String) {
        print("Primary button clicked for offer: \(offer)")
    }
}
Make sure you have at least one campaign active in RevenueFlo and test on a real device to experience your offer paywall exactly as your users will see it.
