Implementing subscriptions in Swift using StoreKit 2 is a straightforward process that allows developers to manage in-app purchases effectively. StoreKit 2 simplifies the creation and handling of subscription products, enabling a more seamless user experience.
// Import StoreKit
import StoreKit
// Define a class to handle subscriptions
class SubscriptionManager: ObservableObject {
@Published var products: [Product] = []
// Fetch subscription products
func fetchSubscriptions() async {
do {
let productIDs: Set = ["com.example.app.subscription"]
products = try await Product.products(for: productIDs)
} catch {
print("Failed to fetch products: \(error)")
}
}
// Purchase a subscription
func purchase(_ product: Product) async {
do {
let result = try await product.purchase()
switch result {
case .success(let verificationResult):
switch verificationResult {
case .verified(let purchased):
// Handle successful purchase
print("Purchase successful: \(purchased)")
case .unverified(_, let error):
// Handle unverified purchase
print("Purchase unverified: \(error)")
}
case .userCancelled:
print("Purchase cancelled by user.")
default:
print("Purchase failed.")
}
} catch {
print("Failed to purchase: \(error)")
}
}
}
