[Anonymous]

Вот код, который я использую для покупки продуктов с помощью StoreKit2. Куда мне звонить прослушиваниеimport StoreKit
import AmplitudeSwift

class PurchaseManager: ObservableObject {
// A published property to hold available products
@Published var products: [Product] = []
// A published property to track the status of transactions
@Published var transactionState: String = "Idle"

// A set of product identifiers
private let productIdentifiers: Set = [
PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID,
PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID_50_OFF,
PaymentHandler.sharedInstance.MONTHLY_PRODUCT_ID
]

// Shared instance to be used throughout the app
static let shared = PurchaseManager()

private init() {}

// MARK: - Fetch Products from App Store
func fetchProducts() async {
do {
let products = try await Product.products(for: productIdentifiers)
self.products = products
} catch {
print("Failed to fetch products: \(error.localizedDescription)")
}
}

// MARK: - Handle Purchase
func purchaseProduct(product: Product, source: String) async -> Bool {
do {
// Start the purchase
let result = try await product.purchase()

// Handle the result of the purchase
switch result {
case .success(let verificationResult):
switch verificationResult {
case .verified(let transaction):
self.transactionState = "Purchase Successful"
await transaction.finish()
return true
case .unverified(let transaction, let error):
self.transactionState = "Purchase Unverified: \(error.localizedDescription)"
await transaction.finish()
await showMessageWithTitle("Error!", "There was an error processing your purchase", .error)
return false
}
case .userCancelled:
self.transactionState = "User cancelled the purchase."

Amplitude.sharedInstance.track(
eventType: "payment_cancelled",
eventProperties: ["PlanId": product.id, "Source": source]
)

case .pending:
self.transactionState = "Purchase is pending."

await showMessageWithTitle("Error!", "There was an error processing your purchase", .error)
@unknown default:
self.transactionState = "Unknown purchase result."

await showMessageWithTitle("Error!", "There was an error processing your purchase", .error)

Amplitude.sharedInstance.track(
eventType: "payment_failed",
eventProperties: ["PlanId": product.id, "Source": source]
)

}
} catch {
self.transactionState = "Purchase failed: \(error.localizedDescription)"

await showMessageWithTitle("Error!", "There was an error processing your purchase", .error)

Amplitude.sharedInstance.track(
eventType: "payment_failed",
eventProperties: ["PlanId": product.id, "Source": source]
)

}
return false
}

// MARK: - Listen for Transaction Updates
func listenForTransactionUpdates() {
Task {
for await result in Transaction.updates {

}
}
}
}
